1. ZC-1. P21 resin contains wax and does not contain accelerators and thixotropic additives.
2. When selecting heat-resistant and chemical-resistant anti-corrosion resin, the appropriate resin should be selected based on the actual medium and temperature of the product, and the company’s “Heat-resistant and chemical-resistant medium usage inquiry form” and confirmed through tests.
3. Post-curing of heat-resistant and corrosion-resistant FRP products is particularly important. The products should be used after they are fully cured.
