Enclosed water dispersible polyisocyanate coating crosslinking agent,Is to put the enclosed polyisocyanate crosslinking agent with hydrophilic modification, make this kind of product can disperse in water in the resin system. Under the condition of high temperature baking, blocking agent will unlock from system, release the isocyanate groups, isocyanate groups to react with hydroxyl groups.
Enclosed water dispersible polyisocyanate crosslinking agent is mainly used as high temperature baking system of crosslinking agent. The main purpose is in the car of the original paint coating, on the other hand, there is also a part of the application in waterborne industrial coatings. Enclosed water dispersible polyisocyanate crosslinking agent with melamine crosslinking agent with, with melamine crosslinking agent to reduce the cost, enclosed water dispersible polyisocyanate crosslinking agent to improve performance.
Polyisocyanate since the 1860 s began to be used for two-component polyurethane coatings and two-component polyurethane coating has become a mainstream technology in the field of many applications, such as car repair paint, large transport industrial paint, wood paint, plastic paint, etc. And along with the social attention to environmental protection, can reduce the emissions of volatile organic high-performance crosslinking agents such as water dispersible crosslinking agent and crosslinking agent, low viscosity will be the focus of future development.
Water-based resin based on water instead of organic solvent as a dispersion medium system of new type resin. Form solution, mixed with water, after waiting for water to evaporate, form the resin mold material. Not water-based resin with acrylic resin itself, but the water evaporated, membrane materials.
Water-based resin includes three categories: water-soluble polymer, high water absorption resin and coating, is developed since the 70 s, new field of polymer science. Since it has a series of unique irreplaceable function, with the continuous development of scientific research and production, the industrialization of the products, has been formed an independent industry, belong to the category of fine chemical industry. Due to water-based resin has a very wide range of USES, with extremely high value added, over the years has been listed as the key point of the development of the chemical industry.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine
English name: Benzenediamine, ar, ar-diethyl-ar-methyl-English aliases:Diethyltoluenediamine; ar, ar-Diethyl-ar-methylbenzenediamine;Diethylmethylbenzenediamine;

EINECS No. :270 -877-4
Molecular formula: C11H18N2
Molecular Weight: 178.28
Boiling point: 310 ℃
Refractive index: 1.581
Flash Point: > 140 ℃
Inchi: InChI = 1/C11H18N2/c1-4-8-6-7 (3) 10 (12) 11 (13) 9 (8) 5-2/h6H ,4-5,12-13H2 ,1-3H3 density : 1.022
Risk Codes: R10; R35
RIDADR: UN 3082
Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
Replace solvent-based products application in all fields. Waterborne polyurethane as a representative, can be widely used in coating, adhesive, textile coating and finishing agent, paper surface treatment agent, leather finishing agent and fiber surface treatment agent.
Architectural decoration. Including floor paint, elastic paint, building exterior wall paint, furniture wood coatings, water-based interior wall coating.
Industrial coatings. Including car paint, industrial paint, anti-corrosion paint, water-based paint, metal surface treatment (polishing); Plastic water-based paint (is applied extensively in the field of consumer electronics), etc.
Water-based paint do diluent water instead of organic solvent, therefore does not contain toxic chemicals. (before dispersing medium for organic solvent, organic solvent containing toxic substances, completely vaporize clean need at least several decades, for children and unborn baby has a great impact on the child's mental development is, in which "the free TDI" also has the risk of cancer.
Water-based paint film after features: high adhesion to substrate, after curing coating corrosion resistance and excellent chemical resistance, coating closed reduction, high hardness, good wear resistance, corrosion resistance, electrical insulation performance, etc.
Melamine, commonly known as melamine, protein powder, IUPAC named "1,3,5 - triazine - 2 minus 2 - three amine", is a kind of organic nitrogen heterocyclic triazine compounds, used as chemical raw materials. It is a white monoclinic crystal, almost tasteless, slightly soluble in water (3.1 g/L) at room temperature, soluble in methanol, formaldehyde, acetic acid, hot ethylene glycol, glycerin and pyridine, insoluble in acetone, ether.
Melamine formaldehyde condensation polymerization can be obtained with melamine resin, can be used in plastics and coating industry, also can make textile technology to fold, shrink proof treatment agent. The modified resin can be bright color, good durability, hardness metal coating. It can also be used for decorative sheet strong, heat-resisting, moistureproof paper and grey leather tanning agent, synthesis of fireproof layer board adhesive, waterproofing agent, fixing agent and curing agent. By melamine and formaldehyde, butyl alcohol as raw materials of 582 melamine resin. Used as a solvent polyurethane coating flow ping agent, the effect is very high.
