Modified barium borate used in the coating industry, its outstanding characteristics have a variety of effects, modified barium borate in the coating with rust, mold,bacteria, pollution, powder resistance, prevent discoloration, flame retardant and other functions, is a multi-functional anti-rust pigment.
1. Rust prevention
Used in primer, it has excellent protective effect.
2. Anti-fog effect
The durability of the paint film and the decorations are attacked by mold and bacteria. There are many factors that affect the shedding of paint film, and the
polymerized paint film can be used as food by microorganisms. It has become more and more obvious that the paint base of the interface between the paint film
and the bottom layer is used by bacteria, which is an important factor of the paint film shedding, which occurs at the bottom layer interface.
Modified calcium metaborate is a kind of highly effective anti-mold agent which can control the growth of mold for a long time and prevent mold from multiplying.
This is due to the release of barium and metaborate ions by modified calcium metaborate, where barium ions can interfere with the passage of soluble nutrients
through the microporous film and prevent the reproduction of enzymes. Boron compounds block oxidizing enzymes because modified barium metaborate is a good buffer and can maintain water-based latex paint at alkaline pH, which is not conducive to mold and bacteria growth.
3. Resistance to pulverization
Due to the erosion of the paint base by bacteria, the destruction of ultraviolet light and the action of moisture, the destruction of the paint film makes it powder.
Barium metaborate is an effective anti-pulverizing agent in coating industry. Its degree of resistance to pulverization is proportional to the amount used in the
paint,
4. Flame retardant effect
The flame retardancy of borates was first used in textiles and other coatings. Because the modified metaborate has the characteristic of small water solubility, it
has a long retention time in textiles and coatings, so it has more advantages than other borates. The modified barium metaborate can effectively replace part of
antimony trioxide when combined with halogen-containing materials. Generally, it can be replaced by 50%, and a greater proportion of replacement is to use
modified barium metaborate in combination with other flame retardants. The modified barium metaborate has good thermal stability and higher decomposition
temperature than other flame retardants.
