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.

Storage and Transportation:

STORAGE: It is recommended to store in a dry and cool area with proper ventilation.
