Temporary removable solvent based protective coating

摘要

This invention is for a composition of clear or pigmented coating that is temporary and removable. It is especially designed to protect the surface of an automobile from the damaging effects of the environment and also from damage caused by normal daily use. The coating is a composition of 40 to 80% of cellulose acetate butyrate ester, 15 to 60% of an acrylic polymer and 2 to 10% of a sucrose acetate isobutyrate. The remover is a combination of tetrahydrofurfuryl alcohol, dibasic ester, diacetone alcohol, ethyl 3 ethoxypropionate; 2,2,4 trimethyl-1,3 pentanoldiol monoisobutyrate, and white mineral oil.

1. A process for protecting a surface of a substrate, comprising
A) applying a formulation to the surface, wherein the formulation comprises the following ingredients in a solvent comprising at least one alcohol:
i) cellulose acetate butyrate ester at 40 to 80% dry weight of the total dry weight of the formulation;ii) at least one acrylic polymer at 15 to 60% dry weight of the total dry weight of the formulation; andiii) sucrose acetate isobutyrate at 2 to 10% dry weight of the total dry weight of the formulation; and B) drying the formulation to form a temporary removable dry coating on the surface, wherein the substrate is an automobile, vehicle capable of moving, marine or aeronautical craft, equipment or machinery, wherein the at least one acrylic polymer is a methyl methacrylate and n-butyl methacrylate copolymer.
