Essential Polymers R4188

Essential Polymers R4188 is a high-solids aliphatic polyurethane dispersion designed to impart superior abrasion resistance. R4188 delivers a combination of film hardness, flexibility and toughness which makes it an ideal PUD for topcoat applications. R4188 is ideal for the formulation as a sealer or topcoat for masonry-type substrates to protect against the migration of soluble salts through these substrates. R4188 has shown to have excellent efflorescence resistance properties.
