Q&A About Polyurethane
Researchers have identified a number of global trends that will have an impact on the adhesive business. One major trend is to use energy more efficiently—both to protect the environment by reducing carbon emissions and from a basic cost-of-energy standpoint.
We manufacture prepolymers with an isocyanate content of 15-20% NCO using a variety of diphenylmethane-based isocyanates and polyether polyols.
I am developing an adhesive for an application that requires heat resistance greater than 80°C. A formulation based on a waterborne polyurethane polymer currently provides the best adhesion to the substrate and is a fit for the application process. What approaches can be used to achieve the required level of elevated temperature performance?
I would like to achieve the high performance of a two-component polyurethane coating, but my application process is only able to handle a one-component system. Can any existing formulations help me make this performance leap?
Certain polymer-based adhesives are described as crystalline, while others are described as amorphous. How do these adhesive polymer types differ? What advantages could be expected from each type?
