Elvacite® 2041 is a high–molecular weight poly methyl methacrylate (PMMA) resin used in coating applications requiring abrasion resistance and slip characteristics.
Elvacite® 2041 is an acrylic resin based on poly methyl methacrylate (PMMA). It has a very high molecular weight that provides the films it produces with outstanding abrasion resistance, blocking resistance, and slip characteristics. Elvacite® 2041 is ideal for creating highly durable films for low-solids coatings, such as spray lacquers. Elvacite® 2041 is soluble in solvents such as esters, chlorohydrocarbons, and some ketones. Films formed with Elvacite® 2041 have relatively slow solvent release.
Due to its exceptional hardness, Elvacite® 2041 should be used in coatings and adhesives for rigid substrates, such as wood, metal, and vinyl. Elvacite® 2041 forms films with excellent resistance to chemicals and weathering. Thus, one of its most ideal applications is as an acrylic resin in topcoats. Elvacite® 2041 is a nonreactive resin, making it useful for altering and controlling the viscosity of reactive systems.
