Painting of molded plastic parts
On substrates that are difficult to paint, such as PP, PP/EPDM blends and GMT, the use of chemical primers leads to good adhesion results.
Our standard solvent-based products for this application are TRAPYLEN® 112 X, 130 X, 135 X, 137 X, 139 S and 920 X.
Standard aqueous products for coating molded parts are TRAPYLEN® 6600 W, 6700 W, 6800 W, 9600 W, 9350 W 30 and 9700 W
TRAPYLEN® can be applied directly from a polymer solution as a primer or processed with other binders and pigments as a pigmented primer.
