BYK 2616 is a specially prepared additive used in various formulations. It contains calcium oxide and stabilizing wetting agents. BYK 2616 is capable of removing moisture from systems efficiently. This prevents surface defects such as bubbles and cratering when processing materials using casting and rotational molding processes. BYK 2616 also removes moisture that may enter systems through other components. This enables uncomplicated processing of formulations that have been stored for long periods. BYK 2616 provides benefits such as preventing blistering when applying coatings to various substrates. It also removes residual moisture from certain grades of materials. The stable particle size distribution and simple dosage of the liquid additive simplify processes and minimize fluctuations in performance.
