Resin Type
RADOPOL T400PMC is a medium-reactive, medium-viscosity, pre-accelerated unsaturated polyester resin based on terephthalic acid, designed for the production of pipes and vessels by winding.
Areas of Application
The resin is formulated to be used, with the addition of reinforcement and inorganic fillers, by the winding process for the production of pipes, vessels, and pressure vessels. Production can be continuous or discontinuous, and the resin can be used as the base component in combination with HEMPROPOL I400MC as a liner, or with various types of vinylester resins, depending on the requirements for mechanical and chemical resistance.
