Fluorocarbon surfactant is YM - 313 by the Shanghai rain wood chemical industry co., LTD., independent development and production of coatings with special surfactants by domestic famous fluorine chemical experts as the leader of the research and development team can provide customers with high quality products and perfect technical service, at the same time the company also with domestic famous research institutes maintain close relations of cooperation, with a number of patents.
The product has high surface activity, high heat stability and Gao Huaxue stability and other characteristics, stable quality, performance than similar imported products. Highlight the advantages of this kind of fluorocarbon surfactants have high surface activity, is now known surface active agent in surface activity of the highest.
Wood chemical rain after a long period of experiment research and applied research, found that very small amounts of the product is added in the coating product, significantly higher coating product wettability of the substrate, pigment dispersion, more can make the fouling resistance of coatings.
The physical and chemical indicators:
Surface tension data:
The surface tension of water
1, minimal amount, the cost is low, only need to add 0.1% ~ 0.3% in the recipe that can reflect the good effect, can reduce more other wetting agents, the use of defoaming agent, effectively reduce the cost;
2, significantly improve wettability, greatly reduce the surface tension of the coating system, improve the wettability of coating to the substrate and flow property, especially suitable for water-based wood coatings, water-based plastic paint and other materials used in;
3, pigment dispersion, improve the dispersion effect of pigments in coating system, more to improve the storage stability of coatings;
4, compound with good sex: add in waterborne coatings, and most other additives can effectively dissolve, does not destroy the original coating system;
5, improve the fouling resistance: fluorine surfactant in the process of film forming gradually migrate to the film surface, latex particles form tight dry film package fillers, have migrated to the gap after the evaporation surface of fluorine surfactant, and closely and orderly arrangement, surface layer containing fluorine alkyl greatly reduces the surface tension of the dry paint film, give film hydrophobic, hate oily, improve the paint film bonding resistance, fight corrupt ability.
It is recommended to use methods
After the company long-term experiments and the joint research cooperation units, YM313 coating with special fluorocarbon surfactants in coating suggested use according to the following recommendations:
*, 0.1 0.3% of total amount of formula can be used to achieve the ideal effect;
* the process of production, it is recommended to use before and after grinding ratio of 7:3 is added;
* reduce other appropriate wetting dispersant dosage, prevent possible interference;
In use process if have other problems, please timely call Shanghai rain wood chemical industry co., LTD., our technical staff will promptly provide you with better advice.
