SP SEAL COAT HT is a single-component hybrid resin, water-based coating using specific ceramic loads for application directly over HPC to seal and face up to 500°F (260°C). It was designed to provide a seal for HPC to block water/moisture absorption and seal the surface. HPC offers a ‘green’, non-flammable, non-toxic formula for surface applications. SP SEAL COAT HT is easily applied and can be applied direct to HPC. It will give additional protection for CUI development.
