DRAGONSHIELD-HT® ERC is a state-of-the-art, high-performance, sprayed, plural-component pure polyurea elastomer. This system is based on amine-terminated polyether resins, amine chain extenders and MDI prepolymers. It provides a flexible, resilient, tough, monolithic membrane with water and chemical resistance.
100% solids. No solvents. No VOCs.
Fast-set: Handle in two minutes or less. Hydrophobic, therefore unaffected by damp, cool surfaces during application
Extended tack time to allow deep surface penetration
High dry temperature stability to 250o F (121o C) with intermittent temperatures to 300o F (148o C)
High abrasion resistance
ASTM E84-97a and complies with NFPA and UBC Class 1 Fire Rating
Coating for steel or other substrate exposed to corrosion
Liner for concrete tanks, ponds, lagoons, reservoirs, dikes, irrigation ditches, tunnels, barges, etc.
Replace or repair failed existing sheet membrane liners
Steel tanks, silos, and pipes
Encapsulation material for EPS or other types of flotation materials
Encapsulation material for asbestos, lead paint, or other dry hazardous materials (Consult SPI)
Earthen containment used with or without geotextile
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.
