A definition of “bio-based” is a good starting point for this discussion. The U.S. Department of Agriculture (USDA) defines bio-based products as those derived from plants and other renewable agricultural, marine, and forestry materials. Standardized tests have been developed (ASTM D 6866) to quantify the bio-based content of a product or a raw material.
Companies using adhesives are expected to be able to consistently produce an assembly―whether in the flexible packaging, furniture, automotive or construction industry―without differences in the quality of the product manufactured. This is the case for both high-performance structural bonds and applications with lower performance requirements.
I work in the technical department developing coatings based on various polymer backbones. I am familiar with typical polyurethane raw materials, but have recently become aware of polyaspartic coatings. Could you provide an overview of this technology?
I am an adhesives manufacturer and, as business is increasing, I have a need for a larger warehouse for the polyurethane and polychloroprene raw materials used. How should these raw materials be stored to optimize their shelf life?
I am familiar with formulating polyurethanes for adhesive applications, but would like to learn more about coatings raw materials in order to provide a broader product profile to my customers. Can you provide some general information?
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.
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?
