Elvacite® 2028 is a low–molecular weight methacrylate resin that is highly soluble and compatible. It is an ideal binder for flexographic inks, lacquers, and metal coatings.
Elvacite® 2028 is a thermoplastic methyl methacrylate acrylic resin with a low molecular weight. It is a solid-bead acrylic resin with low intrinsic viscosity that is soluble in alcohols, ketones, toluene, and glycol ethers. Owing to its low molecular weight, this acrylic resin carries unique properties amongst Elvacite® resins by having broad solubility and forming films with a high degree of flexibility. As such, Elvacite® 2028 is an ideal binder for flexographic inks, where it is also highly compatible with most pigments and additives used in printing inks.
When used as a film former, Elvacite® 2028 acrylic resin produces durable films resistant to heat, chemicals, UV degradation, and weather. These films have fast solvent release and are often the basis for pigmented lacquers and metal coatings. Elvacite® 2028 is an excellent binding resin for coil coatings that require durability, gloss, and cost-effectiveness. Coil coatings formulated with Elvacite® 2028 offer outstanding protection from moisture, corrosion, and abrasion, in addition to best-in-class clarity and gloss.
