BRB Siloen® SMA 283 is a 100% polyether modified siloxane developed to improve slip and mar resistance as well as anti-blocking properties of coatings at very low dosage. It helps flow, levelling and anti-crater. BRB Siloen® SMA 283 is suitable in water based polyurethane wood coatings and even UV curing polyurethane systems. It also brings excellent properties in solvent-based coating like nitrocellulosic wood varnishes.
