DE NEEF® Denepox I-40
Two Component Epoxy
DE NEEF® Denepox I-40 is an ultra low viscosity, 100% solids, two component, moisture insensitive epoxy injection resin system designed specifically for gravity feeding or pressure injection of cracks. Its ultra low viscosity allows for gravity feeding of even hairline cracks on horizontal surfaces. DE NEEF® Denepox I-40 is moisture insensitive and can be applied in damp to dry (not wet) conditions. This product may be injected with multi-ratio pump or due to its long pot life, it may be “hot potted” with a single component pump.

Packaging & Handling
Approximately 1 gallon units
(92 fl oz. “PART A” & 32 fl oz. “PART B”)
Shelf Life: A minimum of 1 year in original, unopened container.
Storage: Store in a dry area, between 40°F and 95°F. Protect from direct sunlight.
Surface of application should be clean and sound. The surface must be free of dust, oil, grease, laitance, curing compounds, or any other contaminants. It may be dry to damp, but must be free of standing water. The very best results are obtained on dry concrete. Do NOT apply on surfaces, which have been sealed with a permanent type of form oil, curing compound or release agent. Remove these substances before application. The surface temperature must be 40°F and rising. Refer to DE NEEF® Surface Preparation Guidelines for more details.
Mixing Procedure: Stir each component separately. Mix 2.85 parts A with 1 part B by volume into a clean mixing container. Mix the epoxy with a slow speed drill with a mixing paddle attachment. Carefully scrape the sides and bottom of the pail during mixing with a paint stirring stick. Blend for 3 minutes. Mix only the amount of materials that can be used within the pot life.
Please note: Large batches of epoxy will cure much faster than small batches. Mixed epoxy will cure much faster in hot weather than in cold weather.
Application: For gravity feeding: mix appropriate amount of epoxy, 2.85 parts A to 1 part B by volume and pour onto properly dammed or widened crack to keep epoxy from spreading. As an injection epoxy: Mix and metering equipment is recommended. Please contact DE NEEF® Construction Chemicals or your local representative for detailed instructions.
Clean-Up: Remove uncured DE NEEF® Denepox I-40 from tools and equipment with a suitable solvent such as xylene or toluene immediately after use. Cured material may only be removed mechanically.
