D2800 Secondary Diamine Polyether Polyurea Resin
D2800 Secondary Diamine Polyester that includes Ionogen Group with adhesion on molecular chain. Same performance as D-2000.
D2800 Secondary Diamine Polyether Can quick react with MDI Prepolymer or Semi-Prepolymer with -NCO Ionogen group, creates polyurea elastomer. Apply in R component of SPUA(Spreaing Polyurea Elastomer) as main resin.
As D2800 molecular includes Ionogen Group, can increase adhesion on concrete, metal surface, epoxy primer, also can improve adhesion between polyurea coat film(Polyurea film to polyurea film).
Increase gel time.
Quick reaction with -NCO, no affected by water and wet weather.
Increase adhesion of spraying polyurea coat to substrate or coat.
Good weather resistance.
