COMPOSITION FOR THE APPLICATION OF A PROTECTIVE LAYER TO A SUBSTRATE AND METHOD FOR THE APPLICATION THEREOF

摘要

The present invention relates to a composition comprising: (a) about 5 wt. % to about 30 wt. % of an amorphous polymer, said amorphous polymer having a glass transition temperature of lower than about −20° C., (b) about 15 wt. % to about 60 wt. % of a filler, and (c) about 10 wt. % to about 80 wt. % of a solvent, wherein the amounts of (a), (b) and (c) are calculated on the total weight of the composition. The present invention also relates to a process for the application of a protective layer to a substrate, the process comprising application of a layer of the composition to the surface of the substrate or a part thereof. The present invention further relates to a container comprising the composition and a propellant.

1. A composition comprising:
(a) about 5 wt. % to about 30 wt. % of an amorphous polymer, said amorphous polymer having a glass transition temperature of lower than about −20° C., (b) about 15 wt. % to about 60 wt. % of a filler, and (c) about 10 wt. % to about 80 wt. % of a solvent, wherein the amorphous polymer is selected from the group consisting of: (i) a polymer comprising about 50.0% to about 98% by weight of isobutene and about 2% to about 50.0% of a C2-C12 alkene other than isobutene, a C4-C12 alkadiene, or a mixture thereof, based on the total weight of the polymer; (ii) a polymer comprising more than 98% to about 100% by weight of isobutene, based on the total weight of the polymer; and (iii) a mixture of (i) and (ii), and wherein the amounts of (a), (b) and (c) are calculated on the total weight of the composition.
