BJB Polyurethane SP-200 A/B BJB Enterprises Polyurethane Thermoset Elastomer

Product Description

SP-200 A/B is a two component rigid polyurethane material designed to provide high strength, high impact, and good heat resistance for the fabrication of structural parts, composite type structures, and for coatings that serve many purposes.
During the spray application, coating thickness builds quickly due to the 97% solids composition of the system. Spray tests demonstrate that the SP-200 A/B will not foam or blister during or after application. SP-200 A/B bonds readily to itself during build-up and it shows excellent bonding results sprayed against other plastics, wood, and metals.
The SP-200 A/B has an extremely low V.O.C. content. The volatile organic compounds (V.O.C.) contained in the mixed A and B components total less than 40 grams per liter. This translates into a great advantage for compliance with health, safety, and environmental programs.
The SP-200 A/B has a set time (dry to the touch) of approximately 2 minutes. It demolds quickly, often within 10 to 15 minutes after sprayup is completed. Spraying SP-200 A/B requires two-component airless spray equipment that develops a high-pressure impingement mix/spray to obtain the best processing results. BJB offers the CPE-600 Spray System specifically set-up to spray this product.
