Product Description

Vapor-phase silica
A200
Features and advantages:
A200 is a kind of vapor silica with a specific surface area of 200M2/g. Used for anti-settlement, thickening, anti-flow hanging additives; Rheological and thixotropic control of liquid systems, adhesives, polymers, etc. HCR-RTV-2K silicone rubber reinforcement; Used to regulate free flow and as an anti-caking agent to improve powder properties, hydrophilic silica vapor phase.
It is suitable for each paint layer (adhesive, coating, ink, powder coating) to improve the stability of pigment, improve the dispersion of pigment, improve the adhesion of paint film, anti-corrosion, waterproof, prevent bubbling; Especially silicone rubber, polyester resin, paint and ink thixotropic agent, coloring system of anti - sedimentation agent. For liquid system, rheological control, solid suspension, rheological protection and other effects can be obtained. For the solid system can improve the strengthening effect, for the powder system to provide good free flow and prevent caking effect; Can also be used in natural and synthetic rubber, medicine and cosmetics and other high active filler;
