Water-clear aliphatic polyurethane pultrusion formulations and processes |
摘要 |
Clear polyurethane fiber reinforced composites are produced by a pultrusion process with a polyurethane-forming system that includes: (a) a clear, aliphatic polyisocyanate having a viscosity at 25°C of no more than 1000 centipoise, (b) a colorless polyol component comprising an amine-initiated polyol having a molecular weight of from about 150 to about 400 and an OH functionality greater than or equal to 3, and (c) a catalyst. These fiber-reinforced composites are characterized by both excellent weathering characteristics and excellent physical properties. |
