POLYOLEFIN-BASED COATING COMPOSITION
Abstract:
The present invention provides a paint formulation that has good storage stability and weather resistance, and that is capable of forming a paint film having excellent water resistance, chemical resistance such as gasohol resistance and fuel resistance, and adhesion. The paint formulation comprises an acid-modified polyolefin (A) and a tackifier (B), and satisfies the following (a) and (b): (a) the acid-modified polyolefin (A) has crystallinity; and (b) the tackifier (B) has a double-bond equivalent of 40 or more, as defined by the formula: double-bond equivalent=weight average molecular weight/number of double bonds in a molecule, or contains no double bond.
