We only sell top of the line, 100% solids, epoxy resin blends to ensure the highest quality installations while still protecting the environment. Epoxy resins are inherently free of odors, HAP, and volatile VOC emissions. They also provide superior adhesion and are virtually shrink free compared to styrene making them the best choice for CIPP applications. HammerHead® epoxy resins have a proven track record in conjunction with felt, woven or fiberglass liner materials.
HammerHead® epoxy is a single resin system with multiple choices of 4:1 (by volume) curing agent hardeners. HammerHead Epoxy resin is tinted transparent blue, and the hardeners are transparent yellow. When the resins are properly mixed, a uniform aqua green color is achieved.
With a working time of 30–35 minutes (@77° F), our standard hardener provides a good balance between working time and set time (1–3 hours with heat curing). (4:1 resin to hardener by volume).
A longer working time (50–60 minutes at (@77° F) is useful when used in hot weather or for long or large diameter pipe runs. Also provides a higher temperature resistance which allows it to be used for projects in high temperature applications (up to 240°F). Set time of 1.5–3 hours with heat curing (4:1 resin to hardener by volume).
This blend provides 12–15 minute working time, useful for winter and short run applications requiring a fast return to service. (4:1 resin to hardener by volume).
The extended blend is formulated for longer working times useful in long runs, larger diameter pipe or higher temperature working conditions. Working time is extended to three hours (@77° F) while still keeping a fast set time range of one to four hours with hot water or steam cure. (100:30 resin to hardener).
Our ambient resin system is specially designed for ambient curing, even at temperatures as low as 35º F. It has a consistent working time of 25–30 minutes (@77° F) with a set time of only 1.5–2 hours. (2:1 resin to hardener by volume).
