Essential Polymers R4370

CASE Ingredients Features: Chemical ResistanceExcellent AdhesionHigh GlossImproved FlexibilityImproved HardnessLow VOCMar Resistance
Chemical Family: Acrylics & Acrylates

Essential Polymers R4370 is a urethane/acrylic hybrid, is solvent-free; allowing for coatings to be formulated to <100 g/l while still offering a balance of hardness and flexibility. For improved resistance, Essential R4370 can be cross-linked with either a polyaziridine or a trimer. These 2K systems exhibit excellent gloss and exceptional chemical and mar resistance. Essential R4370 has shown excellent adhesion to various substrates; in particular, wood, concrete and cold-rolled steel.
