Baking varnish composition

Abstract

The invention discloses a dissolvent type baking lacquer composition comprising polyester resin, amino article, polyester modified polydimethyl siloxane, silicon dioxde and dissolvent by a specific proportion. The composition can overcome the drawbacks of long hardening time of the conventional baking lacquer, it has high glossiness, high ductility, and can lower baking temperature and shorten curing time. íí

Description

technical field [0001] The invention relates to a solvent-type baking varnish composition, in particular to a solvent-type baking varnish composition for lowering the baking temperature and shortening the curing time. Background technique [0002] Baking paint has developed very rapidly in recent years, and many formulas have appeared. These formulas conform to a certain extent with the mechanical properties of the varnish solution on metals tested by national standards, such as stiffness, toughness and anti-aging performance. The disadvantages of amino compounds are: longer curing time and higher baking temperature, which will not only affect the adhesion, smoothness and mechanical properties of the stencil, but also consume a lot of energy. Thereby reducing production efficiency and increasing costs. Contents of the invention [0003] The purpose of the present invention is to provide a fast curing solvent-based baking varnish composition with high gloss, high adhesion...
