Afcona -3581

Afcona -3581 by Afcona Additives is organically modified polysiloxane. Acts as a leveling and anti-crater agent. Offers improved anti-crater behavior, better substrate wetting, no intercoat adhesion properties as well as little or no foam stabilization. The slip performance, due to the small molecules, is less. Afcona -3581 is used in electroplating and electro deposition coating to avoid crater formation as well as giving a smooth, good leveling and good appearance coating. Addition and dosage: 0.1 - 1.0% on total formulation. In general, under normal conditions, the dosage is 0.1 – 0.3% based on total formulation.
