It provides a flexible, resilient, tough, monolithic membrane with water and chemical resistance.

Product Colours

It should be noted that DRAGONSHIELD-HT® ERC is an aromatic polyurea, therefore, as with all aromatics, color change as well as superficial oxidation will occur.

Aliphatic urethane, polyurea, and other suitable topcoats can be used when long-term aesthetics, and increased longevity in full sun exposure are of critical importance.
