摘要： Aqueous polyurethane dispersions and coatings and heat-activatable adhesives made from the dispersions are disclosed. The dispersions include a polyurethane reaction product of a polyester polyol and a polyisocyanate. The polyester polyol comprises recurring units of at least one C2-C6 aliphatic diol, at least one aliphatic or cycloaliphatic C4-C10 dicarboxylic acid, and an aromatic diacid source, which can be recycled PET. The dispersion is formulated using 1 to 3 moles of an acid-functional diol per mole of polyester polyol. Dispersions for the adhesives are produced at NCO/OH molar ratios within the range of 0.90 to 0.98. The adhesives successfully bond a wide range of plastic and metal materials, often demonstrating substrate failure, even with steel. This contrasts with commercial adhesives such as EVA that exhibit only adhesive failure with the same substrates.

摘要： Disclosed a no-added formaldehyde composite wood product binder, a no-added formaldehyde composite wood product manufactured by same, and a preparation method for the composite wood product. The no-added formaldehyde composite wood product binder comprises an agent A and an agent B. The agent A is an isocyanate-based binder, and the agent B is an aqueous dispersion of polyester based aliphatic polyurethane and/or a modified polyester-based aliphatic polyurethane. The no-added formaldehyde composite wood product is formed under hot-pressing after a wooden and/or straw material is mixed with the no-added formaldehyde composite wood product binder. The composite wood product manufactured by the no-added formaldehyde composite wood product binder has excellent water-proof and mechanical properties and a good saw cutting performance, and the amount of isocyanate used is also reduced, thereby reducing costs.
