phenolic resin (phenolic resin) is a phenolic or its derivatives and aldehydes polycondensation resin, the original is colorless or yellowish brown transparent, the market sales of products are often added with coloring agents and red, yellow, black, green, brown, blue and other colors, in particles or powder. It is divided into two categories of thermosetting and thermoplastic resins. The cured resin has high mechanical strength, good rigidity, heat resistance, flame resistance, ablation resistance, and good dielectric properties.

| physicochemical properties | Usually refers to the liquid or solid products obtained by the action of phenol or its homologs (such as cresol, xylenol) and formaldehyde. Depending on the type of raw materials used, the ratio of phenol to aldehyde, and the type of catalyst, two different types of thermoplastic and thermosetting resins can be prepared. Thermoplastic phenolic resin (novolac resin, novolak resin) only melts when heated and cannot become insoluble and infusible. However, after adding a curing agent (such as hexamethylenetetramine), it can be converted into thermosetting, with trifunctional or difunctional phenols as raw materials, and the amount of phenol (mol) exceeds the amount of aldehyde (mol) and acidic catalyst. Thermosetting phenolic resin (thermosetting phenolic resin) becomes insoluble and infusible when heated. Phenolic resin acid, alkali and heat resistance. |
| Product use | Used as a tackifying resin for chloroprene adhesives and a vulcanizing agent for butyl rubber. Store in a cool, ventilated warehouse, away from fire, heat source. |
Properties:
Phenolic resin has excellent heat resistance, chemical resistance, mechanical properties and insulation properties.
2, has good adhesion, can firmly bond a variety of materials.
3. It has excellent wear resistance and corrosion resistance.
Uses:
Used as an adhesive: widely used in the bonding of wood, paper, glass fiber and other materials, the preparation of plywood, synthetic wood, etc.
2, used as a coating: can be used as wear-resistant coatings, anti-corrosion coatings, etc.
3, used as plastic: can be used for the preparation of high temperature plastic, insulation materials, etc.
4, for the preparation of refractory materials, friction materials, insulation materials, etc.
Method:
Generally, phenolic resin is obtained by condensation of phenol and formaldehyde under alkaline conditions. The reaction process usually requires the addition of a catalyst, such as iron oxide, copper oxide, etc.
Safety information:
Phenolic resin is irritating to skin and eyes, and protective equipment is required during operation.
2, long-term exposure or inhalation of phenolic resin vapor may cause respiratory irritation and skin irritation.
3, should avoid the phenolic resin exposed to high temperature or open flame, in order to prevent its decomposition of harmful gases.
