Multiple amine coatings modified crosslinking agent

Multiple amine coatings modified crosslinking agent, because of its easy operation, all kinds of good performance and is widely used. But there is a volatile, smell and brittle big defects, such as to this, the researchers conducted a modification work.

With 2 kind of aliphatic diamine and 1 kind of alicyclic diamine was prepared with epoxy crosslinking agent, namely 2 - methyl amyl diamine (MPMD, trademark for DYTEK? A), 1, 3 - amyl diamine (DAMP, trademark for DYTEK? ER) and 1, 2 - ring hexamethylenediamine (DCH99).

This kind of crosslinking agent, low toxicity, low odor in the preparation of the coating with good resistance to chemical corrosion resistance, high hardness and good luster. The MPMD crosslinking fast, shallow; DCH99 low viscosity, crosslinking slower, adding acid catalyst after color deepened; DAMP the lowest viscosity, the most shallow color, the crosslinking speed between the former two.

Special crosslinking agent XZ92441.01 anticorrosive coatings can be used in the industry; D.E.H. 58 for mixed amine crosslinking agent, can quick drying at room temperature. European patent reported a low viscosity, and do not contain environmental harmful substances (e.g., phenol and solvent) crosslinking agent of epoxy resin, polyurethane compounds and crosslinking promoter, its composition can be low temperature crosslinking, and crosslinked film appearance and excellent performance.

Series of high performance epoxy crosslinking agent, modified multivariate amine, CX - 101 which have long-term anticorrosion sex; CX - 110 - b with low temperature crosslinking, used for heavy-duty and Marine coatings; X - 2282 and X - 110 - e USES weak solvent, the former can quickly crosslinking, all can be used in anticorrosive coatings; IM - 544, I - 90 s, NB - 90 - s and W - 100 are solvent-free products, all can used in anticorrosion and floor coating.

IM - 544, I - 90 s is low odor, weather resistance varieties; I - 90 s also has a wet leaching properties, can be used for the surface treatment requirement is not high situation; NB - 90 - s both weathering resistance and low temperature crosslinking; W - 100 with low temperature quick crosslinking, also can be used as a cross-linking promoter.

According to the report, hexamethylenediamine and aliphatic glycidyl ester and alkyl sheet after the reaction of glycidyl ether crosslinking agent, the crosslinking material has good storage stability, bending resistance, low temperature resistance and chemical resistance.

Modified hexamethylenediamine crosslinking agent C - 200 series, can be used alone, or with other spell with crosslinking agent, can eliminate the internal stress of crosslinking content, improve the flexibility and impact resistance.

CGF - 1 was synthesized using ldpe-g-nvp was modified amine type low viscosity resin toughening epoxy crosslinking agent, the ratio of raw materials, reaction time and reaction temperature on the performance of the product. This product can normal temperature crosslinking, coating flexibility is good, easy to bubble, good liquidity, chemical character. After the test, the physical and mechanical properties of crosslinked far better than that of the commercial products.

Also, dimethylamine with benzene as the basic raw materials, such as acrylonitrile and epoxy compound as the modifier, with 79-3 modified amine epoxy crosslinking agent. 79-3 crosslinking agent easy to use, low toxicity, crosslinking reaction, crosslinking product has excellent electric properties, moistureproof performance and mechanical performance, especially prominent impact strength.

In DACH amino cyclohexane (1, 2, 2) alicyclic amine crosslinking agent based on modified, to market a kind of high performance epoxy crosslinking agent. The crosslinked product has good chemical resistance and high glass transition temperature, shore hardness of up to 90, and in the humid environment can keep the high gloss.

Gong Yunjin using hexamethylenediamine epoxy resin with hydroxyl alkylation and cyanide ethylation reaction were prepared with acrylonitrile TG301 crosslinking agent at room temperature, the low melting point, low toxicity and low brittleness of comprehensive effect.

Multiple amine is not belong to a polyol, but it in polyurethane synthesis with polyol up effect similar to that of strictly speaking the polymer obtained cannot be named pu, shall be referred to as poly (amino formamide or polyurea, however, as a people will usually polyurethane class discussion.
