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. 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. SP-200 A/B can be sprayed with conventional plural component high pressure spray equipment or with BJB's CPE-25 and CPE-40 pneumatic hand held spay guns.

Product Highlights:

Provides very rapid production of parts, composite structures, and molds

Provides excellent surface finishes built on polyurethane rigid foam and styrofoam

Superior adhesion to a wide variety of substrates, most notably rigid foams and wood

Excellent impact resistance coupled with high flexural strength

Provides very fine detail reproduction

Convenient 1:1 by volume mix ratio

Note: Physical properties obtained from test specimens post cured per recommended procedure.After demolding, allow parts to further cure at room temperature for 2 to 4 hours. It is recommended that parts be post-cured at 120-130°F (49-54°C) for 2 - 4 hours, followed by 4 - 6 hours at 180 ± 10°F (82 °C). Support may be needed for certain configurations during this process.
