Based on the background regarding acrylic matting resin selection, the resins currently on the market can be categorized in various ways to suit different application scenarios:
Classification by film-forming/curing system
UV-curing acrylic matting resins
These are primarily based on modified polyurethane acrylates-such as pure aliphatic polyurethane acrylate matting resins. They can achieve gloss levels below 5 units and offer excellent yellowing resistance and scratch resistance. They are widely used in UV wood coatings and UV soft-touch coating systems; some products provide an inherent velvety, smooth feel, enabling a refined matte finish without requiring large amounts of additional matting agents.
Thermosetting acrylic matting resins
This category includes types such as epoxy-functional acrylic matting resins, which are typically used in conjunction with curing agents like TGIC or HAA. They represent a mainstream type in the powder coating industry. By adjusting the epoxy equivalent weight, manufacturers can control the matting rate and cross-linking density. These resins offer excellent outdoor weatherability and chemical resistance, making them ideal for matte powder coating applications in sectors such as construction and automotive components.
Air-drying acrylic matting resins
These are based on modified thermoplastic acrylic resins. As single-component systems that air-dry at room temperature, they offer convenient application and easy recoating or rework. They are commonly used in plastic coatings and printing inks, with some specially modified grades offering high adhesion and resistance to alcohol wiping.
