VP 5063 Water-soluble defoamer

5063 is a high-performance water-soluble defoamer, primarily composed of polyether-modified polysiloxane. It is engineered for aqueous systems where foam suppression and rapid de-aeration are critical. Unlike traditional oil-based antifoams, the 5063 variant exhibits exceptional solubility and stability in water, preventing common issues like oil spotting, “fish-eyes,” or surface defects in sensitive applications like textile dyeing or high-grade coatings. Its molecular architecture allows for low surface tension, enabling it to penetrate foam lamellae efficiently. It operates effectively across a wide pH range and remains stable under high-shear conditions or elevated temperatures. It is an ideal choice for complex industrial processes such as metalworking fluids, industrial cleaning, and textile auxiliaries. By maintaining low viscosity and high dispersibility, the 5063 defoamer ensures consistent performance without compromising the integrity of the final product. It represents a versatile solution for modern chemical processing requiring both high efficiency and ease of incorporation within various aqueous matrices.

Attributes

Key Features and Benefits
