TYVcure UVM
Methacrylate Resins
TYVcure UVM has been developed for UV-cured pipe rehabilitation processes. The resin suits for relining and short-liner repair at the same time. The resin can be used as a matrix material for in-situ or for pre-impregnated composites.
TYVcure UVM resin is a methacrylate-based, one-component system that already contains the necessary UV initiator. The resin is completely Styrene-free. The viscosity of the resin can be modified with a thixotropic agent, the amount of which should be adjusted according to the specific application.
