Baytec SPR-066A is a two-component, 100%-solids spray system with a Shore hardness of 66A. The isocyanate component is a modified diphenylmethane diisocyanate (MDI) prepolymer, and the polyol component is a polyether polyol blend. The system has added UV stabilizers and is used in spray applications to improve the corrosion, weather, and abrasion resistance of metal, concrete, wood, plastic, PVC, and porous organic and inorganic materials. In-mold spray application is also possible. Typical applications are liners for dump bodies, garbage trucks, pipes, and tanks, as well as protective layers for flexible foam, wood, and industrial surfaces. This system is also available as a grey/black-pigmented system, Baytec SPR-166A (product code U832). As with any product, use of Baytec SPR-066A in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
