POLYSHIELD HT- SL™ is a fast-set, high-performance, spray- applied, plural-component, pure polyurea elastomer. This system is based on amine-terminated polyether resins, amine chain extenders and prepolymers. It provides a flexible, tough, resilient monolithic membrane with good water and chemical resistance.
100% solids. No solvents. No VOCs.
Fast-set:Handle in one minute or less.
Hydrophobic,and therefore affected very little by damp,cool surfaces during application.
High temperature stability to 250°F(121°C)with intermittent temperatures to 300° F (148 °C).
High abrasion resistance.
High elongation for crack bridging.
Excellent encapsulation characteristics.
Compliant with FDA/USDA for incidental food contact.
Coating for steel or other substrate exposed to corrosion.
Liner for concrete tanks, concrete floors, ponds, lagoons, reservoirs, dikes, irrigation ditches, tunnels, barges, etc.
Replace or repair failed existing sheet membrane liners.
Steel tanks, silos, and pipes.
Rock shield for pipelines.
Planter box liner.
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.
Concrete parking decks.
Wood deck coating.
POLYSHIELD HT- SL™ is available in SPI standard colors (Sand, Medium Grey and Black). Custom colors available upon request. It should be noted that POLYSHIELD HT- SL™ is an aromatic polyurea; therefore, as with all aromatics over a period of time color change and superficial oxidation will occur.
POLYSHIELD HT- SL™ is available in a high-pigment, UV inhibited formulation for stand-alone applications, such as roofs and containment liners.
Aliphatic urethane, and other suitable aliphatic topcoats can be used where long-term aesthetics are of critical importance.
