When recoloring plastic an adhesion promoter should be used prior to applying color. But, before you jump in to using any adhesion promoter, you first must know if you have ABS plastic or not. So how do you find out what kind of plastic you have?
- Place a drop of acetone on the back of your plastic and rub with a gloved finger.
- If acetone makes the plastic smear/melt it is ABS plastic.
- If nothing happens to the plastic after the acetone is applied, then you do not have ABS plastic.
So, after you determine the type of plastic you have you can now pick your adhesion promoter.
- ABS Plastic - Sand Free
- Non ABS Plastic - Plastic Adhesion Promoter or XXX Adhesion Promoter
You are then ready to apply your adhesion promoter then your color.
