Complete analysis of hydrophobic agents for water-based coatings

Introduction:Water based coating hydrophobic agent is a mixed compound that, after surface modification by scientific technology, disperses in water to form a stable dispersion. When added to the coating, it can form a special water-resistant structure on the film-forming surface of the coating (changing the contact angle), which has stronger hydrophobic, hydrophobic, and waterproof effects on the surface. At the same time, the hydrophobic agent of water-based coatings does not affect the breathability of the coating, which not only avoids the poor recoating performance of organic silicon hydrophobic materials, but also avoids the situation of poor breathability of other hydrophobic agents. 

characteristic:The hydrophobic agent of water-based coatings gives the coatings good properties such as double hydrophobicity, self-cleaning, hydrophobicity, waterproofness, stain resistance, and scrub resistance. This product is particularly suitable for water-based coatings.

Technical indicators: The technical indicators of hydrophobic agents for water-based coatings are shown in the following table: 

usage method: 

① It can be added to the coating in its original form or as a pre diluted substance;

② After grinding, add the product and dilute it;

③ Dilute with water; 

④ The recommended addition amount is 1% -6%, and the specific situation can be determined according to the needs.

Scope of application: 

Water based coating hydrophobic agents are suitable for various water-based coatings, water-soluble resins, water-based emulsion resins, water-based pigments, water-based inks, etc.

Storage: 

The hydrophobic agent of water-based coatings should be stored in a closed container below 40 ℃ to prevent freezing, and the effective shelf life is 6 months.
