Elvacite® 4254
Elvacite® 4254 is a hydroxy-functional methacrylate copolymer resin used as an acrylic polyol in low-VOC, two-part polyurethane systems.
Elvacite® 4254 is a low–molecular weight solid bean resin that typically functions as an acrylic polyol component of low-VOC, two-part polyurethane systems. When reacted with an isocyanate, the Elvacite® 4254 copolymer forms polyurethane films with exceptional durability. Elvacite® 4254 provides outstanding abrasion and UV resistance as well as better optical properties due to excellent gloss and water-white transparency. This resin offers a favorable balance of flexibility and hardness in many coating applications. Since it has a low molecular weight, it also enables high-solids, low-VOC formulations to be made. Elvacite® 4254 can be used for creating protective topcoats and has low reactivity with pigments, making it ideal for formulating colored basecoats as well.
The hydroxyl functionality of Elvacite® 4254 makes it useful in reacting with other polymers to form other hybrid resin systems, such as polyester-acrylic or epoxy-acrylic systems.
Low–molecular weight resin provides good melt flow and enables formulation of high-solids coating systems Excellent dispersion and adhesion Good balance of flexibility and hardness Great durability, UV resistance, and chemical resistance High reactivity with other polymer and copolymer resins through hydroxyl functionality Good pigment wetting
Problems Solved
High-VOCs in solvent-based coating systems from use of high-molecular weight resins Yellowing and discoloration from prolonged UV exposure Low scuff resistance and durability Poor color strength
Elvacite® hydroxyl- and amine-functionalized acrylic resins are ideal for two-component coating and adhesive systems, where they increase durability, adhesion, and visual quality. Learn more here.
