Types and characteristics of main extinction agents Types Features Organic matting agent (synthetic wax) It can not only extinction, but also increase the surface smoothness, enhanced hand feeling and anti-settling property of the coating film. However, such matting agents often affect the transparency of the coating film and even affect the interlayer adhesion of the coating film. Inorganic matti...

There are four common waterborne polyurethane thickeners: ①Inorganic thickeners, such as flake silicates, fumed silica, etc.; ②Natural organic thickeners, such as cellulose ethers; ③Synthetic organic thickeners, such as polyacrylates, polyvinylpyrrolidone; ④associative thickener. This paper mainly introduces the associated emulsion thickener. Associative emulsion thickeners are non-ionic synthetic...

How to Master Molecular Weight Control in Acrylic Resin Synthesis
- 2026-04-11 16:19:47

Acrylic resin synthesis is fundamentally a free-radical polymerization process, consisting of chain initiation, chain propagation, and chain termination, often accompanied by chain transfer throughout the reaction. For thermoplastic acrylic resins, controlling molecular weight and molecular weight distribution is critical. While increasing molecular weight improves the mechanical properties o...
