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.

Important product note

Product information on this page is provided for general informational purposes only. Performance depends on application, site, operating conditions, and compatibility with the rest of the system. If a Polinvent product is used together with third-party equipment, liners, resins, curing units, or other components, that combination requires written Polinvent approval. Otherwise, the customer must verify suitability and bears the integration and project-performance risk. Review the applicable SDS, TDS, and product manual where relevant. Binding specifications arise only from the Confirmed Order and the written technical documentation supplied by Polinvent.
