Protective coating with crosslinking agent
2017-4-5 11:06:30
Protective coating with crosslinking agent,Coating formula of one of the most important requirement is the crosslinking degree formula system, because many of the features are derived from this feature. Gel content determination of the crosslinking degree can well reflect the formula.
Two kinds of silane added for gel content has great influence. This means that two kinds of additives in the crosslinking density of reaction is very big, but CoatOSil * MP 200 silane gel content is slightly higher. The results also indicate that although after six months of ageing, the two formulations are still maintain its reactivity and stability, shows the two products are resistant to storage products.
Formula of high gel content helps to improve chemical resistance of cured coatings, which can be obtained by the fouling resistance test validation. CoatOSil * MP 200 silane is added to the styrene acrylic emulsion to improve ammonia corrosion resistance of coating, at the same time maintain the superior performance of stain resistance.
Used in the emulsion formulation CoatOSil * MP 200 silane another benefits can be seen in the results. This test record is the coating hardness change process with time.
After treated ESO emulsion than reference solution (do not add any additives) or Silquest * A - 1871 silane treatment formula of curing speed faster. In addition, the formula of hardness hardness is bigger than the other two's formula, which means that the ESO CoatOSil * MP 200 silane crosslinking efficiency is higher.
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. In addition, due to the amount less, have relatively low VOC emissions: ESO 70% lower than the silane monomers of VOC. These results can be extended to many areas of coating industry. Solvent-free ESO can also be used for used silane monomers of solvent or solvent-free formulation.
When using another method to assess ESO application in the water system, we surveyed the CoatOSil * MP 200 silane scatter metallic pigment in water.
Paint and ink containing metallic pigment in the paint and printing ink industry is often referred to as metallic paint and metallic ink. Their applications in coatings industry, including motor vehicles and other machinery coating. In printing ink industry applications, due to the reaction between metallic element and water, metallic paint extremely difficult to disperse in water.

Metal elements and water corrosion products such as metal oxide generated in the reaction and the amount of hydrogen gas. This phenomenon is known as the hydrogen evolution, higher rate of hydrogen evolution in the anionic emulsion, as a result of the aqueous solution pH value is usually characterized by alkaline. Aluminum and zinc particles in the dispersion of the system is very poor.
So should be used contain metallic pigment or particles, and the amine curing agent of epoxy resin/hardener three components of the system. 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.
Using a new type of ESO to solve the problem of metallic pigment cannot disperse in water. Prepared with CoatOSil * MP 200 silane to water-based epoxy zinc-rich primer, generally used as a protective coating. As mentioned earlier, silane can be used for glass and metal surface modification agent. Through reaction with ESO is the purpose of this special application to improve the properties of metal particles surface inhibit the generation of hydrogen. After processing of metal particles are more likely to spread in the formula, to reduce the hydrogen produced in the container.
To introduce the silane as a primer in method has two kinds: 1) the scattered metals to silane hydrolyzate, slurry or paste dispersed in the resin; 2) hydrolyzed to metal particles dispersed onto a silane/resin in the mixture, then hydrolyzed silane dispersed in the resin. In the two methods, silane must be fully hydrolysis,
silane crosslinking reaction. Using ESO CoatOSil * silane and monomer MP 200 general hydrolysis of the silane Silquest * A - 187 program to see the contents of the methods and materials section.
