For more than two years, GCP Applied Technologies has donated their self-adhered weather resistive barrier, Vycor® enV-S™, to the Weitz Construction Academy in Loxahatchee, Florida. The collaboration to build homes for Habitat for Humanity of Palm Beach County.

Vycor® enV-S™ provides an advanced alternative to house wraps and is the latest in residential building science to create an air-tight, yet breathable home. It is a highly durable membrane that directly adheres to the sheathing, avoiding the tears and costly reworks commonly associated with traditional house wraps. The wall is protected from water damage and the job site looks neat, sealed and attractive even during construction.

"We have a great relationship with GCP," said David Porter, Weitz Construction Academy volunteer architect and project manager. "Not only have they donated a lot of product, GCP has sent a representative to the school to teach the students how to install their products."

Vycor passes the hurricane test

"(GCP's) Vycor® enV-S™ weather resistive barrier is a standout product, even passing our highway wind test every time," Porter said. "Before installing siding on the module home, we transport the home from the school workshop to the Habitat job site. The truck drivers put Vycor® enV-S™ to the test by hitting the highway at 70mph during the trip. We call it our 'Category 1 hurricane test' and it has survived nicely without a hint of peeling away. Prior to discovering Vycor® enV-S™ and working with GCP, our use of standard building wraps ended up with most of it pulling away from the sheathing, like sails in the wind!"

"Our partnership with the Weitz Construction Academy has been a great experience and opportunity for GCP," said GCP Applied Technologies’ Marketing Director Sonya Santos. "The program provides weather-protected and affordable homes for hardworking families in Palm Beach County. Hundreds of students have benefited from the opportunity to learn important career skills, training the next generation of construction professionals. The academy’s unique mission is inspiring young students and teaching them the latest construction techniques in all trades, while giving back to the community."

GCP expert will present study on manufactured sand in concrete at Thai conference

 

GCP expert will present study on manufactured sand at Thai conference, centered on innovative concrete solutions for the future

More and more, GCP Applied Technologies' scientists and technical experts have observed the use of manufactured sand over natural sand, as a fine aggregate in ready-mixed concrete.

THE PRIMARY REASON: Environmental concerns have made what remains of available natural sand resources an economically unviable option for the concrete producer.

It's important to note, however, that crushed stone fines and quarry dust alternatives are more abundant, but lack quality. GCP has, therefore, published a paper entitled, "Issues with, and Admixture Solutions, for the Use of Manufactured Sand in Concrete," to study the introduction of GCP concrete admixtures into mixes to achieve a higher quality concrete with manufactured sand.

GCP tech expert Dr. Jiabiao Jiang will present the study at the Thai Concrete Association conference, in Bangkok, Feb. 15-17, 2017. The conference's theme is "Innovative Concrete for the Future of Construction Material."

An excerpt from the paper reads: "The key idea is to develop admixtures with enhanced water reduction capacity to compensate for the increase in water demand and rheology modification to improve the pumpability and finishability of concrete mixes with manufactured sand so that they work just as well as concrete with natural sand."

"We are proud to work with the This Old House crew on another unique home project," said Sonya Santos, Director of Marketing for GCP’s Residential Building Materials business. "It is one of our greatest honors to have our Ice & Water Shield®, which has been trusted for nearly 40 years, used by such a highly trusted brand and team of respected home renovation experts."

The new This Old House® episodes feature the renovation of an Arts & Crafts home in Arlington, Massachusetts. Original Ice & Water Shield®, was used on the roof of the Arlington home to protect it from extreme weather such as wind-driven rain and ice dams. The underlayment seals around the fasteners used to attach the shingles, which helps prevent water build up from leaking into the house. Ice & Water Shield® also sticks to the roof deck so that water may not travel under the underlayment and enter the house via a vulnerable roof deck joint. The episode that includes Ice & Water Shield® is titled “To Paint or Not to Paint, number 1507/3607 and airs on PBS beginning November 10, 2016.

"The This Old House crew also selected our advanced weather barrier, Vycor® enV-S™, an advanced alternative to house wrap. This weather resistive barrier represents the latest in residential building science to create an air-tight, yet breathable home, and achieve the highest product performance available," Santos said.

The well-respected Oak Ridge National Lab tested and evaluated the annual savings potential of Vycor® enV-S™ membrane compared to traditional house wrap. Vycor® enV-S™ weather resistive barrier boasts an air leakage rate seven times lower than the leading house wrap brand. The Oak Ridge Lab also found that using this new and advanced membrane can provide significant energy savings for homeowners in all regions of the United States.

PVC-free Daraform® has touched every champagne bottle in the world

 

The use of PVC-free closure sealants during the champagne maturation process began more than 20 years ago, with Darex®.

PVC-free closure sealants replace cork sealants for less organoleptic variability and constant gas exchange. This avoids the irregular exchange that can occur with the cork.

During champagne maturation, Daraform® PVC-free crown liners are applied to the temporary seal.

Darex® plays a key role in champagne maturation

After crown capping, champagne bottles embark on a long period of maturation on lees—residual sediment that settles in the wine bottle during maturation. Bottles are stored at a downward angle in a cellar kept at a constant temperature of 12°C (54°F).

The crowns are then removed during the disgorgement phase. This is a critical point in the life of champagne, that takes anywhere from many months to years of peaceful maturation on lees.

The purpose of disgorgement is to eliminate the deposit that has collected in the neck of the bottle, while maturing. During disgorgement, the bottleneck is plunged into a refrigerating solution at -27°C (-16°F). The sediment (in the form of a frozen plug) ejects under pressure when the bottle is opened, with minimum loss of wine and pressure.

Finally, the cork is forced into the neck of the bottle, covered with a protective metal capsule, then held in place with a ‘muselet,' or wire cage, to form an airtight seal.

From there, the champagne is ready to usher in a new year, celebrate a wedding or other momentus occasion, or christen a ship ready to berth into the mighty ocean. All of this was possible thanks, in part, to Darex®'s PVC-free closure sealant Daraform®.

GCP's first Australian concrete patent dates back to 1935

 

​GCP Applied Technologies may appear brand new, but the construction materials and packaging solutions producer hails from decades of innovation.

Since the early 20th century, the GCP lineage has filed nearly 900 patents. And here's the first in concrete admixtures


Download the patent in PDF

In 1935, Dewey & Almy applied for a patent in new admixture technology, based on a Lignin derivative. The compound was an effective dispersion agent to produce concrete with lower cost or better strength.

The major cost in producing concrete is cement. And water is needed to mix with the cement so that it becomes pliable, more plastic, making it easy to form, manipulate and to catalyze cement hydration. The more water, the more workable the cement becomes, as well as more hydrated.

The tradeoff, however, is that excess water weakens the concrete. Yet, producers needed to add excess water to achieve the desired cement workability, sacrificing strength or cost.

The Lignin derivate concrete admixture solved for this. The water-reducing agent dispersed cement particles efficiently to grant the desired workability, without having to add excess water.

And voila!

Due to Dewey & Almy's innovative admixture, we have a concrete produced with workable cement, that maintains strength or lowers cost of production.      

Grace Construction & Packaging (the future GCP) would acquire Dewey & Almy in 1954.

DAREX® cover, drum and pail compounds
bottles on belt

 

Metallic drums and pails are often used as packaging for transporting industrial goods and food products. DAREX® drum and pail compounds are used to seal the seam channels of double- or triple-seam steel drums and pails. Many drums and pails are also constructed with an open-top or lid, not seamed, but crimped onto the package. DAREX® Cover Compounds are used to form a seal with the crimped open-top or closing-ring of metal, plastic drum and pail packages.

The Importance of the Sealing Compounds

The hermetic seal performs the following functions:

  • Keeps micro-organisms out of the package, probably its most important function;
  • Prevents seepage of the pack from the drum or pail;
  • Prevents leakage of liquids or vapors into or out of the drums or pails;
  • Maintains the desired vacuum or pressure inside

DAREX® sealing compounds meet the needs of the pack

Sealing compounds of high quality must be used after consideration of the requirements of the pack. The proper type, amount and placement of the compounds are required to obtain maximum sealing efficiency, and resistance to leakage caused by abuse of the body and the end in the double or triple seam area.

Optimal Sealants for Different Sealing Technologies

Double or triple seam applications

DAREX® Drum and Pail Compounds are latex dispersions delivered in a liquid form for application. They are typically dried or cured prior to seaming. In some cases, the product may also be applied wet during the seaming operation. The gasket must be properly compressed during the seaming operation. The compressive force results in controlled movement of the gasket, filling the voids resulting from double or triple seam construction. Compound placement in the seam provides robustness and abuse resistance during container transportation.

Cover applications

DAREX® Cover Compounds utilize two different technologies: Latex dispersion for water-based compounds or PVC dispersions for plastisol compounds; both of them are used for open-top metal covers. DAREX® water-based cover compounds utilize a two component system to create a "puffed" gasket with cell structure to fill large channels in some covers and lids. DAREX® Plastisol Cover Compounds utilize a single component, PVC-resin-based technology. Both water-based and PVC cover compound technologies rely upon proper compression of the gasket during the crimping operation to fill the voids in the cover assembly. DAREX® Cover Compounds are delivered in a liquid form for application and in most segments are cured prior to crimping.

Compound Characteristics

DAREX® products are specially formulated to have good chemical resistance to a wide variety of aggressive packs. The excellent performance of DAREX® compounds in contact with different oils or solvents is largely due to the tendency of the compounds to swell slightly in the presence of these packs, providing additional assurance that any leakage path is filled. DAREX® products do not become brittle when dried. They retain their rubbery, elastic characteristic providing abuse resistance and sealing integrity to the package during handling and transportation of the drum or pail.

In order to get the optimum sealing properties, several considerations have to be taken. The first criteria is to match the selection of the compound with the product that is being packed. Then proper storage and compound conditioning prior to application are important. Compound application (placement, volume, film weight and appearance) and correct drying and curing with the right compression of the gasket will provide the best hermetic seal.
