Acrylic emulsion coating crosslinking agent
CoatOSil * MP 200 silane is used in the formulation in the same way as monomer silane. In emulsion applications, it can be added to the emulsion after the polymer is produced. In this way, we can perform A performance comparison with the same phenopropyl emulsion processed by Silquest * A - 1871 with the same phenylene acrylic emulsion treated with CoatOSil * MP 200.
To achieve accurate comparison, the actual weight percentage of each additive was adjusted to ensure that the active content reached the same level. These coatings and standard phenyl acryl emulsion were tested with gel content, stain resistance and konig hardness.
One of the most important requirements for coating formulas is the crosslinking degree in the formulation system, because many features derive from this feature. The gel content is a good indicator of the crosslinking degree in the formula.
The addition of two silane has a significant effect on the gel content. This indicates that the crosslinking density of the two additives in the reaction is high, but CoatOSil * MP 200 silane is slightly higher. The results also showed that despite the six months of aging, the two formulas remained responsive and stable, suggesting that the two products were resistant to storage.
The high gel content in the formula can help improve the chemical resistance of cured coatings, which can be verified by the anti-contamination test. CoatOSil * MP 200 silane is added to phenyl emulsion to improve the corrosion resistance of ammonia to paint, while maintaining the superior performance of anti-fouling.
Another benefit of using the CoatOSil * MP 200 silane in the emulsion formulation is in the results. This test records the variation of coating hardness over time. It is obvious that the emulsion treated with ESO is faster than the contrast solution (no additive) or Silquest * a-1871 silane processing formula.
In addition, the hardness of this formula is greater than the hardness of the other two formulations, which indicates that ESO CoatOSil * MP 200 silane is relatively efficient.
CoatOSil * MP 200 show a higher silane in anionic emulsion crosslinking efficiency and faster curing speed, which not only improves the chemical resistance and stain resistance, also keep the hardness of coatings.

Also, with fewer additions, the VOC release is relatively low: the ESO is 70% lower than the VOC for monomer silane. These results can be extended to many areas of the coating industry. Solvent-free ESO can also be used in solvent or solvent-free formulations that have been used with monomer silane.
Surface modifiers of metal particles. In an alternative approach to assessing ESO's application in a water-based system, we examined the ability of CoatOSil * MP 200 silane to disperse metallic pigments in water. Coatings and inks that contain metallic pigments are commonly referred to as metallic paint and metallic ink in paint and printing ink industries.
Their applications in the coating industry include other mechanical coatings such as motor vehicles. In printing ink industry applications, metallic paint is extremely difficult to disperse in water because of the reaction between metal elements and water. Metals and water react to corrosive products such as metal oxide and large quantities of hydrogen. This phenomenon is known as the dehydrogenation, which is more rapid in the anion emulsion, and the pH of the aqueous solution is usually alkaline.
Aluminum and zinc particles are very fragmented in these systems. A three-component system containing metallic pigment or particle, epoxy resin and amine curing agent/hardener. Can also be added in the formulation of special additives to alleviate the problem of hydrogen evolution, but they are usually very expensive or difficult to add, to achieve effect may need other special additives.
The use of the new ESO to solve the problem of metal pigments being unable to disperse in water. We use CoatOSil * MP 200 silane to make a water-based epoxy rich zinc primer, commonly used as a protective coating. As described above, silane can be used as a surface modifier for glass and metal. The purpose of this particular application is to improve the surface properties of the metal particles by using the ESO reaction to inhibit the production of hydrogen. The processed metal particles are more easily dispersed in the formulation, reducing the production of hydrogen in the container.
