Varnish resins are a type of resin used in the production of varnishes, which are protective coatings that provide a glossy finish and protect surfaces from damage. ELEMIS is an acronym for Ethylene-vinyl acetate copolymer, a type of thermoplastic polymer used in the production of varnish resins. LACS stands for Linseed Alkyd Copolymerized System, a type of alkyd resin used in the production of varnish resins. Both ELEMIS and LACS are important components of varnish resins, which are used to create durable and attractive finishes on a variety of surfaces.
