Formulating guidelines
- NeoRez R-986 is a very compatible polyurethane dispersion and even suitable for pigment grinding
- Small additions (1-2%) of Crosslinker CX-100 will improve chemical resistance and mechanical properties
- NeoRez R-986 is somewhat softer compared to NeoRez R-985 and the best choice when curing conditions are at ambient temperature
- See our guide formulations for specific information
