Purpose
Dispercoll® S 5005 is an additive for waterborne neoprene adhesives based on Dispercoll® C.
In specific applications, the appropriate viscosity can be obtained by adding nanoscale ZnO to the formulation. The addition of Dispercoll® S 5005 can improve the moisture resistance and heat resistance of water-based neoprene.
