Synthesis and properties of hydroxy acrylic resin with high solid content

Abstract

Thermal conductivity and thermal boundary resistance of atomic layer deposited high-k dielectric aluminum oxide, hafnium oxide, and titanium oxide thin films on silicon APL Materials 6, 058302 (2018) Abstract. Manufacturers of automotive repair finishes are tending to reduce more and more the level of volatile organic compounds in their paints in order to comply with increasingly strict environmental legislation. A high solid hydroxy acrylic resin was synthesised using CARDURA E10 and a type of hydroxyacrylic acid resin, its' acid value, hydroxylvalue, viscosity, structure, morphology was measured and film-forming properties after curing were characterised. The results show that the addition of CARDURA E10 in the copolymer composition significantly reduced the viscosity of the polymer system, improved the solid content of the resin and the physical properties of the coating. The hydroxyl acrylate resin with solid content of 90% and excellent comprehensive performance were successfully prepared by controlling the initiator dosage, polymerization temperature and monomer ratio.

Preparation and Properties of Polyester Modified Waterborne High Hydroxyl Content and High Solid Content Polyacrylate Emulsion

“…This abnormal viscosity is usually reduced by adding a high boiling solvent to a prepolymer or by increasing the amount of the solvent or by directly reducing the content of the hydroxyl group. Therefore, at present, many products have some defects, such as low hydroxyl value, low solid content, high viscosity, high VOC content and insufficient crosslinking density, which leads to an unsatisfactory coating resistance [16]. Zhang [17] used 2-hydroxyethyl methacrylate as a monomer to provide a high content of hydroxyl group.…”
