Water-based epoxy top coatings special crosslinking agent

Water-based epoxy top coatings special crosslinking agent. Popular as environmentally friendly products, powder coating, waterborne epoxy resin coatings special crosslinking agent, crosslinking agent and one-component adhesives broad prospects.

For the direction of the crosslinking agent, the expert inside course of study also proposes to match specific modification technology, such as: fat amine modified, the modified epoxy resin incense amine especially m-phenylene diamine, between benzene dimethylamine modification, acid modification and liquid, the dicyandiamide modified and imidazole modification and liquid and liquid, etc.

The development direction of epoxy resin. In fact, innovation and development of epoxy resin is to make full use of the active epoxy group on the resin grafted, in order to realize the resins, such as interpenetrating network, such as chemical copolymerization method, especially the toughening method and the liquid crystal nanoparticles toughening method is the research hotspot in recent years.
As low carbon green environmental protection coating raw materials side, should have the initiative in the innovation of resin. There are a lot of can draw lessons from, or immature thinking whether can trigger an "exceptional" innovation.

Mentioned about restrictions on VOC content, someone can use out of place in the VOC solvent, such as "modified acetone" replace benzene thinner, need to avoid the disadvantage of volatile fast.

Used for anti-corrosion coatings and powder coatings type solid bisphenol F epoxy resin, viscosity, good impregnation, better corrosion resistance; For solvent-free coatings, adhesives and type of liquid bisphenol F epoxy resin.

Used for uv resistance weather resistance of the coating of alicyclic epoxy resin, as a result of alicyclic structure characteristic, give electrical coating surface resistance and leakage resistance mark, and help to coating color retention and durability; Preparation of high performance finish, uv crosslinking green coating; Used as a flame retardant coatings of bromine generation of epoxy resin.




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).


Used for denso coating of high-purity o-cresol novolac epoxy resin, etc. Such as optical instrument coatings, display tube explosion protection coatings and top floor coating epoxy resin colorless, transparent, flexible and should be wear resistant and easy to crosslinking, this would require the new system compatible with the epoxy resin coatings.

At present, the foreign production of pure epoxy coating showed a trend of decline, only 2.6%, and the epoxy/polyester powder coating has risen to 50%. In addition, a large amount of use and epoxy/acrylic powder coating.

Coating industry towards a low carbon environmental protection green coating; Unique functional coatings; High quality special coatings, etc. Accordingly, the epoxy resin/crosslinking agent should be towards a low carbon environmental greening, functionalization, specialty and fine direction of innovation and development. Completely abandon the traditional industrial chain top as the leading thought, according to the coating on the downstream market demand for continuous innovation. Only in this way, in the face of yao long weak economic situation, to play ZhuDongZhang, survival way.

Epoxy resin and epoxy resin adhesive is non-toxic, but due to the solvent is added in the preparation process and other toxic substances, so many "toxic" epoxy resin, domestic epoxy resin industry is through the modification and avoid to add water, keep the epoxy resin "toxic" true colors. Epoxy resin and additives commonly used at the same time, in order to obtain application value.

Additives according to different USES to select, commonly used additive has the following categories: (1) crosslinking agent; (2) modifier; (3) packing; (4) thinner; (5) other. Crosslinking agent is essential additives, both as adhesive, coating, castable to adding cross-linking agent, epoxy resin can't crosslinking. Due to the use performance requirements are different, the epoxy resins and crosslinking agent, modification agent, fillers, thinners and other additives are also have different requirements.
