Imidazole epoxy coating crosslinking agent
2017-8-2 11:52:27
Imidazole epoxy coating crosslinking agent is widely used in epoxy resin adhesion, coating, pouring, encapsulation, composite material, powder coating, then agent, product layer, paint, insulating paint, etc.
Imidazole type epoxy crosslinking agent of high purity, fine granularity, narrow particle size distribution, while the unit price is high, but the adding quantity is little, the comprehensive use of low cost, general 2 ~ 5% can meet the requirements of crosslinking.
Imidazole epoxy crosslinking agent O C17Z series, A series of C11Z - mz - A and 2 A, 2 ma - OK OK series, is suitable for powder coating, the crosslinking temperature can be lowered to 90 degrees, needs 120 more than 2 ma - OK, applicable to some heat resistance lower base material; C17Z and c11z-a are relatively good adhesion to substrate due to long alkyl chains. Good flexibility and excellent electrical performance (can be used for insulating paint); With proper crosslinking temperature or crosslinking time, Tg can be 160 degrees. The coating PotLife is long and the storage stability is excellent (2MA - OK is the best, followed by 2mz-a, c11z-a, C17Z again); Yellowing is very light or not yellow.
The characteristics of each series are different, but they have the following common characteristics.
1, at low temperature (80 °) reaction heat resistance can be obtained better hardening material.
2. A small amount of catalytic dosage forms that can be completely hardened by adding can be used in the economy and can inhibit the initial viscosity increase of the mixture.
3. Lower toxicity than other amine species.
4. The product is complete, can cooperate with low temperature to harden to long service life of various needs.
5. It is a single compound, without the difference of molecular weight, and the stability of the characteristic can not significantly reduce the service life even if it exerts strong shear force.
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

Initiators and promoters are usually organic peroxides, such as benzoyl peroxide, diisopropyl benzene, isopropyl benzene peroxide, peroxide cyclohexanone, etc. Attention should be paid to the characteristics of high critical temperature, long half-life and stable room temperature. Stimulants generally have transition metal soap (such as naphthenic acid cobalt), tertiary amines (such as dimethylphenylaniline), organic sulfur compounds (e.g., yethyl-carbamide).
Promoter can be used alone can also use several kinds of common, joint should be chosen when using a promoter, relies on the rest of the promoter, the selection of initiator and accelerator, besides considering trigger crosslinking effect, should also pay attention to their strict effect on adhesive solution storage stability. 5.32 acrylic acid thinner for acrylic acid, the organic solvent such as acetone, toluene, dimethylformamide is clear.
Ancamine, 2384 & 2385 specialized and Ancarez, 2384 tie-in use toughening modified alicyclic amine crosslinking agent, color shallow, under low temperature - 10 degrees C can also show the excellent performance, 2385 for fast crosslinked specifications. And need to color light & flexibility at low temperature occasions match (2364)
Ancamine, 1922 a fatty amine modified crosslinking agent, color is very clear and transparent method (plus's 1), very low viscosity (CPS) 10, selling point for the use of 3:1 and similar to that of D - 230, but the crosslinking about five times as fast (150 g, 57 min), electric properties and shock resistance higher than D - 230. In the need to be better than a Jeffamine impact resistance and speed
Sunmide, 301 p high viscosity polyamide mixed amine, using a ratio of 100:60, hydrophobic properties, with 301 ak (hydrophilic) mixed ginseng can increase under the wet surface and the surface adhesion ability, also has a certain flexibility. Underwater repair with yacht ship industry.
