NCO retention (23℃) in mixed with polyol
Schematic of water-dispersed configuration
WB40-100 NCO retention (%) in water dispersion：
Test method: WB40-100/water ratio of 10/90 (NV=10%) mixed and agitated 10 min. at 600rpm;
NCO content of WB40-100 measured after agitation and at indicated time (t) thereafter.
NCO retention (%)=[(NCO% at time t)/(NCO% after agitation)]×100.
