Product description

Baydur PUL 4501 is a two-component liquid polyurethane system for use in composite manufacturing.

Applications

Baydur PUL 4501 is a two-component liquid polyurethane system for use in composite manufacturing. The isocyanate is a modified diphenylmethane diisocyanate (MDI), and the polyol component is a polyether polyol blend. The system has been specially designed for use in pultrusion and gives excellent composite properties, including superior elongation to failure, shear strength and impact resistance. As with any product, use of the Baydur PUL 4501 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.

Storage

Isocyanate Component - The MDI isocyanate must be stored in tightly closed containers and protected from moisture. Processability of this material can be adversely affected by contamination. It will react slowly with water to form polyureas and liberate carbon dioxide gas, which may cause sealed containers to expand and rupture. Recommended storage temperatures are 10° and 30°C (50° and 86°F). The shelf life is six months when stored in closed original containers and stored under the recommended conditions.Polyol Component - The blend will separate on standing and needs to be mixed before and during use. The polyol component is hygroscopic, and containers must be kept closed to prevent absorption of moisture, which can adversely affect processing. Recommended storage temperature is 10° - 32°C (50° and 90°F). Shelf life is 12 months when stored in closed, original containers at 25°C (77°F).
