Applications

Baytec SPR-085A is a two-component, 100%-solids spray system with a Shore A hardness of 85*. 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 and concrete. It also improves weather and abrasion resistance when applied to wood, plastic, and porous organic and inorganic materials. In-mold application is also possible. Typical uses are for the protection of pipes, tanks, fabrics, and wood, as well as protective surfaces for flexible, rigid, and structural foams. The system can be pigmented to almost any color. As with any product, use of the Baytec SPR-085A system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.

Storage

Isocyanate Component — Original containers must be kept tightly closed to prevent contamination with moisture and foreign materials, which can adversely affect processing. The isocyanate component will react slowly with water to form polyureas and liberate carbon dioxide gas, which may cause sealed containers to expand and rupture. Recommended storage temperature is between 15°C to 35°C (59°F to 95°F). Shelf life is six months after receipt of product by customer, when stored in closed, original containers at 25°C (77°F). Polyol Component — The polyol component is hygroscopic, and containers must be kept closed to prevent absorption of moisture, which can adversely affect processing. Storage should be maintained between 10°C to 45°C (50°F to 113°F). Shelf life is 6 months when stored in closed, original containers at 25°C (77°F).

Processing

Baytec SPR-085A system components can be processed and sprayed on both high- and low-pressure equipment. It is essential to have equipment that consistently delivers accurate amounts of both components to the mixed to achieve a high-performance elastomer * These items are provided as general information only.They are approximate values and are not part of the product specifications. ** Physical properties may vary, depending on spray equipment.
