THE ROLE OF THE ADDITIVES IN THE HI-RATIO WATER-BASED INORGANIC ZINC-RICH COATING

摘要

The role of the additives in the formulation of tailor- made coatings for specific applications is very important. By increasing the ratio of silica to alkali ,sometimes is not enough to assure the desired water resistance. Use of an external or internal hardener is required to increase the cohesive strength, temperature resistance, welding properties, etc. of high-ratio, water- based, Inorganic zinc-rich coatings.
