Covestro Baydur® PUL 4501 Liquid Polyurethane
Categories: Fluid

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

Properties / 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.
