Phenolic epoxy coatings crosslinking agent

Phenolic epoxy coatings crosslinking agent,Quick crosslinking phenolic epoxy paint, 100% solids, completely harmless. Can be used for coating of pipe repair, the pipeline's largest operating temperature as high as 200 ℃. Such a two-component, solvent-free epoxy coating layer can be easily reached 40 mil (1 mm) of the dry film thickness. This product provides a better viscosity and wear-resisting performance.

Application: circular weld, valve, device, curved and irregular shape repair pipeline, a new pipeline corrosion protection of metal base material or other need.

Material characteristics and advantages: 100% solids, phenolic epoxy resin; Do not contain volatile organic compounds, excluding isocyanate; Phenolic chemical - used in pipeline, operating temperature up to 200 ℃; Higher wear resistance; Can spray or manual operation; On the bare steel and epoxy powder material viscosity is better; Excellent performance of cathodic disbonding, viscosity and elasticity. Recommended thickness: wet film: 40 mil/layer of dry film: 40 mil/layer.

Phenolic epoxy phenolic epoxy resin is also called F type epoxy resin. In acidic medium phenol condensation polymerization with formaldehyde to linear phenolic resin, again with excess epoxy propane was prepared in the presence of sodium hydroxide polycondensation reaction. The epoxy group content is high, high viscosity, curing product after crosslinking density is high, the fiber reinforced plastic has good physical and mechanical properties. Heat resistance than E type epoxy resin. Mainly used for making various structures, electrical components, etc.

Phenolic epoxy resin (EPN) chemical name linear phenolic glycidyl ether, light yellow viscous liquid, is a kind of heat resistant epoxy resin.

Phenolic epoxy resin, based on linear phenolic resin (Novolac) and epichlorohydrin as raw materials, in the presence of NaOH, reaction. There are several commonly used phenolic epoxy resin.

(1) phenol type phenolic epoxy resin

(2) type o-cresol novolac epoxy resin

(3) bisphenol A type phenolic epoxy resin
Industry application


1. Copper clad in application:

To the production of copper clad, phenolic epoxy resin is generally not used alone, but add in bisphenol A type epoxy resin, cooperate to use. Use it to improve and improve the heat resistance and dimensional stability performance of the product. Phenolic epoxy resin content, generally for bisphenol A type epoxy resin of 20% 30%.

Add A polyfunctional epoxy resin system and the traditional system of bisphenol A type epoxy resin, compared to in order to make it in the process of gluing, hot pressing with similar process conditions, with polyfunctional, with the increase of adding amount of epoxy resin should be appropriately reduce the dosage of the curing catalyst.




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. Application of heat-resistant adhesives

Phenolic epoxy resin as the main body of the adhesive has good adhesive force to the metal substrate, and excellent mechanical properties, had long as structural adhesives used in the aerospace field. Phenolic epoxy resin modified with silicone resin, high temperature resistant performance of this kind of adhesives can be improved.

3. The phenolic epoxy vinyl resin application

4. Used in PCB ink

5. The application of phenolic epoxy coating

Phenolic epoxy groups of epoxy resin functionality is more than 2, ordinary bisphenol A epoxy groups of epoxy resin functionality to 2, therefore phenolic epoxy coating has greater than bisphenol A epoxy coating crosslinked density and stronger corrosion resistance. Phenolic epoxy coating curing with amine curing agent, cured coating has good corrosion resistance, chemical resistance, heat resistance (including heat electrolyte) and abrasion resistance, widely used in ocean petroleum platform of mud tank, sewage tank, storage tank wall, resistant to chemicals such as lining for chemical resistance and temperature tolerance requirements higher anti-corrosion system.
