Silicone de-aerator for casting materials 20ml bubble remover

This highly effective silicone defoamer (bubble remover) is an additive designed to eliminate air bubbles and micro-cavities in liquid casting materials. A special chemical composition based on modified silicone polymers effectively reduces the surface tension of the casting mixture, which significantly accelerates and facilitates the natural rise and bursting of trapped air bubbles on the surface before the curing process begins. The product is ideal for use with two-component silicones, casting resins (epoxy, polyurethane), plaster and other mineral materials, ensuring a perfectly homogenous internal structure and a smooth cast surface without small craters or defects. Due to its high concentration, the additive is dispensed in very small quantities (only a few drops) directly into the mixed liquid mixture before pouring into the mould and should be thoroughly blended in. The bottle is equipped with a precision dropper for controlled dosing and a safety cap.
