Adherant adhesion promotors
Provides good adhesion to PP substrates
PP substrate primers
· It is well-known that surface of PP is very difficult to adhere. Though PP can be surface pretreated with flame or corona, these treatments are limited due to their high cost of equipments or complicated operations.
· These difficulties can be overcome by simply using Adherant PPB as primer or incorporating Adherant PPB into paint to promote adhesion to PP, PP/EPDM substrates. The water, gasoline and heat resistance of dried film are also improved.
