Trapylen® 777 is a modified, low chlorinated polypropylene with reactive groups in order to crosslink e.g. with Desmodur N 3390, Z 4370 or other polyisocyanates. The polymer is dissolved in a mixture of toluene, cyclohexane and butylacetate (ratio: 70+20+10). Main merit is its good adhesion strength on polyolefinic plastics. Adhesion and film flexibility of TRAPYLEN® 777 can be increased when adding maleic modified CPO's like TRAPYLEN® 130 X.
