THS-515 special silica sol product for coating and paper making
THS-515 is an alkaline series of small particle size silica sol specially made by WELL-T. The pH is generally maintained at 10.8-11.5. Due to the characteristics of particle size ≤5nm and relatively large specific surface area, it is specially used in coatings, papermaking and other industries.
Application in coatings: THS-515 small particle size colloidal silica. Because its colloidal particles and contact points increase more rapidly than other silica sols of the same amount, it has strong cohesion and can improve the strength and spreadability of the coating film. , It is widely used in high-grade and special coatings.
Application in papermaking: THS-515 ultra-small particle size colloidal silica, due to its large specific surface area and strong reactivity, can form chemical bonds with cationic surfactants and pulp fibers, and is an important component; the "wet part of papermaking" "It plays a role in retention and drainage, increases the retention rate of cellulose fibers, and improves drainage performance; small particle size colloidal silica can be used as an additive to be coated on the white board to prevent it from infiltrating into water.
WELL-T THS-515 products have been widely used in coatings and papermaking industries; in coatings, it can improve the strength and spreadability of the coating film; it plays a role in retention and drainage in the papermaking industry and improves the performance of cellulose fibers. Retention rate improves drainage performance. As a mature customized silica sol product, THS-515 has been verified by large-scale use by coating and paper companies. It has excellent comprehensive performance, good use effect, and stable quality. It is well received and praised by users.
