Coating USES pt910/912 mixture crosslinking agent. Pt910/912 is a mixture of a mixture of glycolic acid and glycolate, which is developed by Huntsman.
Compared with TGIC, the mixture of the mixture has been used to eliminate its ecological toxicity, but it still has certain exposure toxicity and severe irritation. Because of the reduced level of energy, the reaction activity is lower than TGIC, which needs to be added as a promoter such as DT3126 (Jietonda SA316). The structure of the benzene ring and the triazine ring in the TGIC have declined compared with the triazine ring in the TGIC, so it has no superior performance and no TGIC superiority.
As we all know, trimellitic three glycidyl ester of formic acid is a kind of liquid epoxy resin, in order to make it into a solid and easy to use, Huntsman and its solid terephthalic acid two glycidyl ester compound to be "frozen" gained a solid solution.
But the "frozen" is the stability of the body, under external force such as extrusion or heat up to "flow" and resulting in a decline in the speed of the material viscosity caused out of difficulties, so need good extrusion equipment, sometimes need to repeatedly extrusion to conform to the requirements; Obvious is PT910 system, on the other hand, the storage stability of the powder coating will have a problem, so now mainly adopts a specially designed polyester resin (high Tg) to make things up.
Has been found that even with the extraordinary measures PT910 powder coating system is also difficult to extinction, there seems to be only with the method of dry mixing, so that its application is limited by the further.
As for PT912, Huntsman is new PT910 modified products, 60% 60% terephthalic acid is believed to be two glycidyl ester and trimellitic acid three glycidyl ester mixtures, the main purpose is to further improve the functionality and reactivity and developed.
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
Due to the system in the process of production, storage and application, there are some shortcomings, thus did not succeed in the global scope, but because the system of ecological toxicity is lower, it is only in Europe and North America, there are still some application, but the application has not been reported in China.
Modified polyethylene wax can improve the ability to resist chafing, but it is not recommended as a lubricant. Poly (fluorine compounds (ptfe) and polyethylene wax mixture can not only as a slip agent, according to the type of polyethylene at the same time also can improve the scratch resistance performance. The softer the polyethylene wax, the lower the inherent sliding, the better the anti-damage performance. Conversely, the higher the hardness of polyethylene wax, the higher the inherent sliding, but the lower the coefficient of friction, which means that the performance is not good.
Fischer - Tropsch wax, it is a kind of formula from C52H106 to C56H114 straight chain saturated hydrocarbons, is when the carbon monoxide hydrogenation, in content < 1% when also can improve the slip may just as well. When the solvent of the paint film is required, the mixture of Fischer Tropsch wax and ptfe can be used.
Fischer - Tropsch wax can be regarded as high melting point of paraffin wax, because of lower molecular weight, so compared with polyethylene (modified) has better lubricity, in demanding fingernails scratching sex strong resistance.
The low molecular weight of the silicone resin is sometimes used to improve the performance of the damage, which is usually at a maximum of 0.5%.
