　　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
