preparation example Construction

[0045] In the preparation of the resin composition according to the present invention, the first monomer is necessary. As described above, the inventors have surprisingly found that by introducing a first monomer, an ethylenically unsaturated monomer containing a poly(oxyalkylene) moiety during the preparation of the resin composition, it is possible to maintain the resin composition The high solids content while significantly reducing its viscosity allows the resin composition to formulate solvent-based coating compositions with VOC emissions not exceeding 420 g / L without the need for additional diluents.

[0046] Accordingly, the present invention also relates to the use of the above-mentioned ethylenically unsaturated monomers containing poly(oxyalkylene) segments for the preparation of high solids and low viscosity resin compositions comprising acrylic copolymers according to the present invention.

[0047] Preferably, the components used to prepare the resin compositions ...

Abstract

The present invention relates to a high-solids, low-viscosity resin composition comprising an acrylic copolymer, wherein the resin composition has a solids content of at least about 80 wt % based on the weight of the acrylic copolymer and is utilized at 25° C. The BROOKFIELD viscometer measures a viscosity of 130,000 mPa.s or less, and the acrylic copolymer has pendant poly(oxyalkylene) segments in its backbone.

Description

technical field [0001] The present invention relates to a high-solid and low-viscosity resin composition, in particular to a resin composition comprising an acrylic copolymer. The present invention also relates to a solvent-based coating composition comprising the resin composition. Background technique [0002] In recent years, with environmental concerns, many countries have enacted environmental laws and require further reductions in the amount of VOCs allowed to be released into the air by coating compositions, especially solvent-borne coating compositions. For example, in China, since February 2015, solvent-based coating compositions with a VOC content of more than 420g / L will be subject to an additional consumption tax of up to 4%, which will greatly increase the cost of coating companies. Accordingly, the demand for high solids, low viscosity resin compositions for formulating solvent-borne coating compositions with a VOC content of not more than 420 g / L has increase...
