IOTA-4100 non-foaming defoaming wetting agent

IOTA-4100 non-foaming defoaming wetting agent



This product is a specially modified polysiloxane copolymer. It is a substrate wetting and anti-cratering additive, which can not only wet the substrate, but also prevent cratering, and can also promote flow and defoaming properties. Its unique non-foaming and super-wetting properties can be applied to spraying processes or high-speed rolling processes or difficult-to-wet surfaces/substrates. Suitable for water-based polyurethane, water-based acrylate, and water-based epoxy systems. A very comprehensive product.
