For decades, formulators have trusted the Proven Power of Polyurethane Coatings, Adhesives and Sealants Built on Bayer Technology. They know that polyurethane and polychloroprene raw materials and technical expertise from Bayer MaterialScience enable them to develop leading edge coatings, adhesives and sealants that meet the most challenging performance requirements.

The products listed in the CASE Product Index offer you formulating flexibility for a wide range of coatings - from anti graffiti coatings for walls to high gloss, hard wearing custom coatings for wood furniture and flooring, as well as for concrete and metal surfaces. Bayer products also enable you to formulate tenacious adhesives - special adhesives that bond tricky flexible packaging substrates or strong adhesives that tightly bind dissimilar surfaces in tough construction and transportation applications. Bayer raw materials lend formulating flexibility to a wide range of sealants, too. Choose from 100% solids or waterborne resins.

Bayer has long history with polychloroprene rubber for adhesive applications. Polychloroprene latices have been sold under the Dispercoll® C trade name for adhesive applications for over 25 years. Dispercoll C latices provide a safe and environmental friendly alternative to solvent based adhesives. Dispercoll C latices have been found to be an excellent alternative to solvent based adhesives that used non-flammable solvents. Dispercoll C latices can be used to formulate adhesives which meet many of the VOC regulations and also greatly reduce fire hazards that have been associated with flammable solvents. The advantages of using water borne systems have pushed their growth rate above solvent based polychloroprene adhesives.

Los policloroprenos se han utilizado desde la década del 50 como polímero base para cementos de contacto base de solvente. Su fácil uso y buen rendimiento en gran cantidad de sustancias les ha generado un amplio mercado. Bayer suministra policloropreno para aplicaciones adhesivas resistentes al solvente bajo el nombre comercial de Baypren® y Dispercoll® C para los sistemas a base de agua. Los látex Dispercoll C proporcionan una alternativa segura y no perjudicial para el medio ambiente para los adhesivos a base de solventes. El uso de los látex Dispercoll C ayuda a eliminar la emisión de solventes orgánicos a la atmósfera y reduce ampliamente los peligros de incendio relacionados con los solventes.

Las dispersiones adhesivas a base de Dispercoll® U ofrecen una variedad de aplicaciones posibles en uniones activadas por calor debido a sus destacadas propiedades adhesivas. Éstas comprenden desde laminados 3-D para decoración de muebles en la industria del mueble y laminados al calor para revestimientos interiores de automóviles, hasta la comúnmente muy complicada fabricación del calzado de moda. Dispercoll® U brinda resultados sorprendentes en todas estas aplicaciones debido a su gran fuerza de unión inicial y final para pegar una gran cantidad de materiales naturales y sintéticos. El agregado de un reticulante emulsionable como el Desmodur® DN aumenta considerablemente la resistencia al calor y garantiza una mayor resistencia a la degradación química.
