AFCONA-3580 Short-Chain Polysiloxane Leveling Agent

Product Description AFCONA-3580 is a solvent-free short-chain polysiloxane additive designed for strong anti-crater performance. A key characteristic is its short-chain structure, which helps maintain intercoat adhesion and supports recoating in many systems. It is suitable for electrodeposition coatings and a wide range of water-based coating systems. Note: this product may have a mild foam-stabilizing tendency and should be evaluated with an appropriate defoamer.
