Silicone defoamer is basically made up of different materials. They will use different technologies to process, and present a decentralized mode. All raw materials and links are all without poison. They have the characteristics of relatively fast dispersion and fast consumption, and inhibit foam growth for a relatively long time. Layer characteristics.
