Solid Phenoxy Resin – The Dominant Formulation Type
Solid phenoxy resin is the largest formulation type in the phenoxy resin market, commanding a significant share due to its robust chemical and thermal resistance, making it the preferred choice for paints, coatings, and adhesives. Solid phenoxy resins are typically supplied in pellet or flake form, offering excellent stability and superior performance in demanding applications.
Understanding Solid Phenoxy Resin
Solid phenoxy resin is a high molecular weight thermoplastic polymer that is typically supplied as translucent white pellets. It offers excellent stability and superior performance in demanding applications, including high-temperature environments and chemical exposure. PHENOXY™ PKHJ is a high-viscosity phenoxy resin known for its excellent thermal stability, adhesive strength, and vapor barrier properties. It has a molecular weight of 57,000 Da and is soluble in polar, aprotic solvents like MEK, cyclohexanone, and glycol ethers.
