From elastic sealants to high-strength adhesives
Arcol® polyether polyols for nonsolvent adhesives and sealants
Polyurethane adhesives and sealants have many applications across several industries because their properties can be designed to suit each specific application. The choice of polyol, for instance, has a direct influence on the elasticity of polyurethane adhesives.
Polyether polyols have low viscosities combined with excellent resistance to hydrolysis and good physical stability.
We have developed extensive expertise in polyurethane technology since we first introduced polyurethanes to the market in the early 1940s, under the brand Bayer.
We have leveraged our knowledge of how different polyol structures impact polyurethane performance to develop Arcol® polyether polyols.
When combined with Desmodur® isocyanate crosslinkers, Arcol® polyethers are used to formulate soft, low modulus construction joint sealants and rigid high-strength flooring adhesives.
Products in the Arcol® portfolio include diols, triols and polymeric polyols. The molecular weights of Arcol® polyether polyols range from below 300 to as high as 6,000.
In addition to the formulation of nonsolvent adhesives and sealants, our Arcol® polyether polyols are effective in elastic and elastomeric coatings as well as molded and flexible foams.
