Isocyanuric acid triglyceride paint crosslinking agent[TGIC, Triglycidyl isocyanurate]
Three for TGIC (2, 3 - epoxy propane) - both triazine - 2 minus 2 (1 h, 3 h, 5 h) three ketone, chemical structural formula is as follows: it has to do with bisphenol A epoxy resin have bigger difference. First, it has a small molecular weight, and it has three groups that can respond to it, so it has a high density when crosslinking. Second, the rigid urea ring structure of the molecular skeleton, which makes the membrane hardness of the crosslinking, and has a strong light stability; In addition, the nitrogen content of the other molecules is up to 14%, so there is a certain amount of flame retardation and self-extinguishing.
TGIC is actually one of the earliest crosslinking agent for outdoor powder, it not only provide good weather resistance, excellent resistance to bake yellow degeneration, but also has other comprehensive satisfactory performance.
Can provide variety is complete, a full range of high and low light, texture, super weather resistance and high and low temperature crosslinking and other varieties, so widely used in powder coating. But TGIC to human skin, eyes, etc excitant is well known, in recent years further study also shows that TGIC can make the mutagenicity of animal cells, changing some structures of the group, and this change also has transmissibility.
As a result, the proportion of Europe's use of TGIC has fallen sharply in recent years, and the powder that is made from TGIC must be stamped with toxic labels. Today the crosslinking agent to European outdoor powder has been turned to give priority to with beta hydroxy alkyl amide structure, occupied large proportion of TGIC is still in the Asia Pacific region, but turned to the trend of TGIC is increasingly obvious. So the development and utilization of non-tgic outdoor systems has become inevitable.
The role of surface scratch resistance and increase slip agent is to improve the smoothness, scratch resistance, abrasion resistance and the adhesion performance, thereby reducing the processing and mechanical damage when using the coating products.
Because there is some ambiguity in the literature, Verkholantsev offers the following definition: slippage is a low surface friction resistance; An anti-surface injury or injury is the ability to resist the damage of a sharp or hard object. Anti-friction is the damage that can withstand rough or hard objects. Resistance to adhesion is the ability to prevent surface adhesion.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.
Density 1.022
Viscosity (20 ℃) ??mPa·ss290±10
Pour Point ℃-9
Boiling point of310°C
Flash Point°C161.1°C
Verkholantsev USES the following explanation to improve the definition: the ability to resist scratches depends on the hardness, as in some elastomer, the ability to resist scratches. The resistance to abrasion implies resistance to scratches, but it also means anti-fouling. The ability to prevent adhesion is to prevent two surfaces from sticking to each other even under pressure.
Smooth surface is refers to the low friction coefficient, and scratch resistance capability, to some extent, they can be improved by adding appropriate additives, its mechanism is as a lubricant. The lubricant can form a lubricating oil film on the surface and fill in the rough surface caused by the slight bulge of the bridge.
This allows the object to slip through the surface without causing mechanical damage. Liquid lubricant refers to a typical low melting wax or silicone. And the additives that can form solid protective membranes on the surface have better protection against bruises, scratches and stickability.
All of these additives and binders only partially soluble and insoluble or are incompatible, when they are on the crosslinking migration to coating surface to form a continuous or sometimes is a continuous coating.
The most common type of polyethylene wax, modified polypropylene wax, a mixture of PTFE and polyethylene powder (also called "poly fluorine compound") or a special silicon resin. Types of low density polyethylene and high density polyethylene wax than more tough, can provide a better abrasion resistance, but high density polyethylene powder has good slip may just as well.
