Elvacite® 4348 is a methyl methacrylate-based resin that is designed for use as a film former in concrete and masonry coatings.It is similar to Elvacite® 2016 but it shows improved adhesion and performance in high humidity environments like around pools.Elvacite® 4348 is available as a non-dusting solid bead that is soluble in aromatics, ketones, esters, and glycol ethers.Solutions of Elvacite® 4348 will form clear films that adhere well to damp concrete and have exceptional gloss and abrasion resistance.An added benefit of Elvacite® 4348 in concrete coatings is that it shows less whitening when exposed to moisture than standard acrylic resins.
