The result of experiments showed that when the proportion between collagen protein and chitosan was 9 : 1 , the amount of plasticizer and cross linking agent was 60 % and 20 % respectively , the properties of film could count to the requirements of using as medical wound dressing
2.
The elasticity polyurethane joint sealing material is one kind of joint sealing materials for concrete pavement joint which can use at normal temperature . it will solidify by chemic - reaction when commix the polyurethane preploymer , cross link agent , filling , plasticizer and catalyzer
3.
Separately , tma can be used as the cross linking agent to make the polyester resin and epoxy resin for the making of thermoset powder coatings , binding agent , and intermedium of dyestuff , medicine , and resin . moreover , tma can be used to make polyester imido coatings which care special insulated paints for motors
