Methacrylate Resins

Shieldcure

Shieldcure is a fire-resistant (self-extinguishing) methacrylate resin developed for UV-cured pipe rehabilitation processes. The resin is suitable for inversion lining repair and can be used as a matrix material for in-situ or pre-impregnated composites. Recommended work temperature range is from -41 °F to +104 °F.

Shieldcure

Application focus

Shieldcure is a fire-resistant (self-extinguishing) methacrylate resin developed for UV-cured pipe rehabilitation processes.

System type

Shieldcure resin is a methacrylate-based, one-component system that already contains the necessary UV initiator and is completely Styrene-free.

Viscosity
