The crosslinking agent for the triglyceride of isocyanuric acid
The crosslinking agent is one of the most important crosslinking agents containing carboxyl group resin, especially the carboxylic acid polyester.
Three different melamine urea acid glycidyl ester crosslinking agent TGIC is the chemical structure of the following: its three epoxy functional groups provide plenty of activity, and the stability of the triazine ring ensures good heat resistance and weather resistance.
After more than 20 years of development, use it as the main crosslinker of outdoor weatherability powder coating system has developed quite mature, can provide variety is complete, a full range of high and low light, texture, super weather resistance and high and low temperature crosslinking varieties, such as this is unmatched by any other system.
To be sure, it was still the preferred crosslinking agent before it could completely replace the new TGIC, a triglycidyl triglycidyl.China is TGIC's largest provider and consumer.Primid due to its main substitute product can't meet like aluminum alloy construction profiles of strict requirements, combined with the United States still use TGIC, so for quite a long time it will not withdraw from the stage.
TGIC synthesis is in ammonium halide or halogenated phosphine, in the presence of catalyst by heating in a large amount of excess epichlorohydrin cyanuric acid, then by using alkaline catalyst halogenated alcohol to take off hydrogen halide generated TGIC products, at the same time distilled from excessive epichlorohydrin, and will get the crude product of purified by recrystallization method.
The theoretical epoxy equivalent of TGIC is 99, but due to some self-condensation and hydrolysis during storage, epoxides are high in value and are within the range of 105 to 110.Low epoxy-value is a very important characteristic of TGIC.
The low molecular weight raw materials in powder coatings can significantly reduce the vitrification temperature (Tg) of the system, which has a negative effect on the storage stability of coatings.The eu has decided that TGIC must use the symbol T label (with the skull and crossbones as a poisonous symbol) since May 1998 and attach relevant risks!In the words.

Functional groups are atoms or radicals that determine the chemical properties of organic compounds.Common functional group carbon-carbon double bond, carbon 3 bond, hydroxyl group, carboxyl group, ether bond, aldehyde group, carbonyl etc.Organic chemical reaction occurs mainly on the functional groups, decide on the nature of organic functional groups, -, - OH, X - CHO, - COOH, NO2 -, - SO3H, NH2, RCO, these functional groups determines the organic matter of halogenated hydrocarbon, alcohol or phenol, aldehyde and carboxylic acid, nitro compounds, or nitrous acid ester, acid, amine, organic matter the amide class chemical properties.

Learn the nature of the organic matter is, in fact, the nature of the functional groups, containing organic matter what functional groups should have the chemical properties of the functional groups, does not contain the functional groups of organic matter is chemical properties do not have this kind of functional groups, this is the study of organic chemistry, especially to recognize the point.
A carboxyl group is a group of hydroxyl groups, which are functional groups of carboxylic acids, which are carboxyl - COOH.
In simple terms, the carboxyl group is a compound composed of CHO.Exactly is a hydrogen atom sharing two oxygen atoms, because C and between two oxygen atoms form large Π key, so the role of the H 2 O are equivalent.
An atomic group consisting of a carbonyl group and a hydroxyl group called a carboxyl group.The carboxyl group is not a simple addition to the carbonyl and hydroxyl groups.For example, the carbonyl group in the carboxyl group becomes very inactive under the influence of hydroxyl group, and does not react with the nucleophilic reagents such as HCN and NaHSO3, and its hydroxyl group is easy to dissociated from the hydroxyl group, indicating weak acidity.In the carboxylate anion, because of the ionization of the electron, the average of the bonding occurs.So its two carbon bonds are actually exactly equal.
