Waterborne coatings enable both the paint manufacturer and user to comply internationally with low VOC legislation and health and safety regulations. In addition to providing effective matting/flatting, the silica must not interfere with the good optical properties needed in clear coatings, and have little effect on the chemical and stain resistance of the final film. Furthermore, the silica must be both compatible with and easily dispersible in the system, to minimise any risk of foaming or pigment shock. There are products within the Gasil range which meet the requirements of these systems.
