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.

Oxygen scavenger compounds for closures
bottles on belt

 

GCP Applied Technologies supplies a complete range of thermoplastic-elastomer and PVC-free closure sealants to meet the sealing requirements of the closure industry. PVC-free closure sealants provide a sealing gasket for crowns, twist-off crowns, roll-on aluminum closures or plastic caps. They also seal bottles and jars for beverages, like beer, champagne, carbonated soft drinks, fruit juice, mineral water, etc.

For humans, oxygen is life, but it's death for beverages

PROBLEM FROM OXYGEN IN BEER

Flavor deterioration
Color Change
Nutrient depletion
Haze formation

SOURCES OF OXYGEN IN BEER

Dissolved in beer
Included air during fill
Permeation through package

Beer. Juice. Tea. Sports drinks. Once they’re bottled, they’re ready to be delivered fresh to the consumer, right?

Not exactly.

Oxygen goes right to work, destroying the freshness and taste of the beverage, from the minute the cap is sealed. Oxygen can get trapped in a bottle’s headspace, dissolve into the beverage itself, or enter through the packaging. Even low levels of oxidation can result in stale beer, sour juice or spoiled tea. All of this leads to returned bottles, unhappy customers and a negative perception of the beverage product.

Freshness vs. oxidation: Make sure freshness wins

It’s a fact. Oxidation will occur unless you take steps to prevent it. Barrier bottles and sealants alone won’t work. The oxygen-scavenging Celox® closure sealant keeps oxygen-sensitive beverages fresh, preserves their taste, reduces returns and protects the beverage brand.

We're on TV: "This Old House"
This Old House

 

Don't miss GCP Applied Technologies' Ice & Water Shield® self-adhered roofing underlayment and latest residential building envelope innovation, Vycor® enV-S™ self-adhered weather resistive barrier, on the renovation of the This Old House® Arts & Crafts project airing Thursday, Nov. 10 (check local listings).

"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 of 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.

VIDEO: Water drips

Ice & Water Shield®: Water drips from GCP Applied Technologies on Vimeo.

 

Water drips.

Water not only drips; it downpours.

Water freezes.

When water forms icicles on a roof, that's usually an indication of an ice dam, where liquid water collects behind an ice wall. Warmer water from higher up on the roof feeds this ice dam as it melts down to the lower, colder section. From here, the liquid water can find cracks and openings in the exterior roof.

Water drips in, unless the roof is equipped with original Ice & Water Shield®, invented by GCP Applied Technologies in 1978. Forming a direct adhesion to the roof deck and itself, Grace Ice & Water Shield® protects the roof from damage caused by Mother Nature.

When #MotherNatureIs an ice dam, rest assured the roof is safe with Grace Ice & Water Shield®.

VIDEO: STRUX® macro fibers provide superior post-crack control

 

The need for synthetic macro fibers in concrete reinforcement came from customers, GCP Applied Technologies Director of Concrete Research Dr. Alex Reider said. Customers wanted the toughness of steel fibers, but without any of the disadvantages like corrosion.

Advantages to STRUX® macro fibers:

  • Faster and safer construction
  • Lightweight reinforcement
  • Superior crack control
  • Non-corroding
  • Enhanced durability

Post-cracking capacity

"The main weakness of concrete is its brittlenesss," Dr. Reider said. "It's very strong in compression, but once it cracks, you've lost everything. Concrete's like glass—very strong until the point of fracture. Then, you have two pieces."

Not so when STRUX® are added to the mix. After concrete cracks, the structure maintains because the macro fibers bridge that crack.

STRUX® lightweight macro fibers, which are more durable and more efficient than steel alternatives, provide superior post-crack control. Even after a fracture, the concrete structure can still bear some load.

STRUX® macro synthetic fibers are a key component of the TYTRO® Shotcrete System.
