Proper Use of Sodium Hexametaphosphate in Coatings

Since 2018, well-known coating companies have adjusted their strategies and implemented price hikes both at home and abroad. This wave of price hikes is driven by cost, but it is also an opportunity for manufacturers of sodium hexametaphosphate used in coating additive. Sodium hexametaphosphate can play a very good dispersing role in coating. Complexing metal ions such as calcium and magnesium in coating makes coating color and dripping performance better.

With the increase of sodium hexametaphosphate content, the effect on besmear brushability is more obvious. When the content of sodium hexametaphosphate is 2%, the coating is relatively thin, with good fluidity but serious flow. After coating, the coating has obvious flow marks and poor effect. When the content of sodium hexametaphosphate in the coating increases to about 6%, the coating can be saturated with the coating, and the brushing is brisk and smooth. Moreover, after coating, the coating will automatically level for a period of time without leaving any traces, while the viscosity is restored. At the same time, the coating with this content has very low dripping property, and the coating after coating can maintain its inherent appearance under the action of gravity, reaching the degree of mutual balance with dripping property.

yucai chemical specialized production: phosphate series production such as sodium hexametaphosphate, sodium pyrophosphate, sodium tripolyphosphate, disodium hydrogen phosphate, industrial phosphoric acid, trisodium phosphate, aluminum dihydrogen phosphate, solid aluminum dihydrogen phosphate, liquid aluminum dihydrogen phosphate, sodium dihydrogen phosphate, etc. have gone through more than 30 years of continuous pursuit and development. thanks to skilled chemical technology and product development, equipment renewal and the establishment of good cooperation and sharing relations with many universities, Yucai phosphate has developed a brand in the chemical industry!
