Coating crosslinking agent is divided into foreign agent and internal crosslinking agent

Coating crosslinking agent is divided into foreign agent and internal crosslinking agent

1, the diplomatic agent

The so-called diplomatic coupler is to join before using, and then react at room temperature, heat or irradiation. Additional crosslinking agents are divided into the following categories: isoisocyanates (jq-1, jq-1e, jq-2e, jq-3e, jq-4, jq-5, jq-6, PAPI, emulsified MDI, and tetrisocyanate). It is a multivariate amine (propylenediamine, MOCA).

The polyethylene glycol (polyethylene glycol, polypropylene glycol, trihydroxymethyl propane).

It's a diglycidyl ether.

The "inorganic" (zinc oxide, aluminum chloride, aluminum sulfate, sulphur yellow, boric acid, borax, chromium nitrate).

Organic compounds (styrene, a-methyl styrene, acrylonitrile, acrylic, methacrylate, glyoxal, nitrile).

Organic silicon (orthosilicate, methyl silicate, trimethoxysilane).

Sulfonic acid (toluene sulfonate, toluene sulfonyl chloride).

Urea acrylate (diacrylate, dimethyl methacrylate, dimethyl methacrylate, TAC, acrylate, HEA, HPA, HEMA, HPMA, MMA).

It is organic peroxide (diisopropyl benzene, peroxide, 2, 4, 2, 4, 2, chlorobenyl).

The metal organic compound (isopropyl aluminium, zinc acetate, acetyl-acetone titanium).

⑿ nitrogen organism class c

Multi-functional polycarbonized diylamine crosslinking agent.

In the case of the case closed crosslinking agent

The isocyanate cross-linking agent




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).


2, stated

Agent means as a kind of monomer on the so-called stated in aggregate into the molecular chain structure of National People's Congress, or as a component added to the adhesive, can stable storage, only when heated to a certain temperature or radiation condition that crosslinking reaction to happen. Agent on common stated alkene monomers, such as hydroxyl ethyl acrylate, acrylic acid, hydroxypropyl acrylate, methyl acrylic acid and hydroxy ethyl methacrylate, methyl hydroxypropyl acrylate, divinyl benzene and N - methylol acrylamide, diacetone acrylamide.

choose

In the case of different adhesives, the crosslinking agent should be chosen for its use, and the crosslinking agent has the following requirements:

The active group of the crosslinking agent can form the crosslinking structure with the component reaction in the adhesive.

The efficiency of the exchange is high, and the stable crosslinking structure can be obtained by adding a small amount.

The speed is appropriate, too fast and too slow.

A combination of several crosslinking agents can be used for optimal synthesis.

The crosslinking agent is stable during processing and storage, without harmful reaction and condensation. No poison, no irritant, no pollution environment.

Special elastomer can be cross-linked by cold &heat curing system based on metal oxide, silanol, resin and amine.
