Cold-polymerized 9# petroleum resin

Cold-polymerized 9# petroleum resin, as an excellent synthetic resin, has a wide range of applications. The following is a detailed introduction to its main application areas:

1.Coating industry

In the coating industry, cold-polymerized 9# petroleum resin can be used as a promoter, regulator, and modifier. When combined with other resins, it can completely or partially replace expensive resins, thereby reducing costs, improving product gloss, hardness, water resistance, stability, and chemical resistance. For example:
In the formulation of phenolic varnish, replacing rosin modified phenolic resin and rosin calcium grease with equal amounts of C9 petroleum resin still meets the standards of phenolic varnish and phenolic enamel, and can greatly reduce costs.

Adding cycloaliphatic petroleum resin to epoxy resin and polyurethane blend paint can improve the hardness, flexural test, water resistance, weather resistance and other indicators of the product.

2.Adhesive industry

In the adhesive industry, cold-polymerized 9# petroleum resin mainly plays a role in providing adhesion, which can improve the adhesive stability, creep resistance, heat resistance and other properties of the adhesive. For example:

Cold polymerized 9 # petroleum resin can replace traditional modified rosin and terpene resins, with low acid value, good miscibility, water resistance, chemical resistance and other characteristics. Adding petroleum resin to adhesives and pressure-sensitive tapes can improve their adhesion, acid resistance, alkali resistance, and water resistance, and effectively reduce production costs.

3.Rubber industry

In the rubber industry, cold-polymerized 9# petroleum resin is mainly used as a rubber softening additive. For example:
Styrene butadiene rubber itself lacks viscosity and hardness. After adding C9 petroleum resin, the molecular chains of styrene butadiene rubber can be segmented, resulting in good viscosity and softening of the product.
C9 petroleum resin can reduce the amount of natural rubber or synthetic rubber used, significantly reducing production costs without changing the quality of rubber products.

The use of petroleum resin can save one raw rubber refining process, shorten the production cycle, and improve economic benefits.

4.Ink industry

In ink manufacturing, cold-polymerized 9# petroleum resin is mainly used as a connecting material, which can accelerate the drying speed of the coating, improve glossiness and fastness, enhance the color development and drying resistance of the ink. Petroleum resin has good compatibility with many components in ink, and for various specifications of printing ink, there are corresponding petroleum resins to meet the requirements of various indicators such as wetting speed, drying speed, solvent release, water and alkali resistance. After petroleum resin is processed into ink, it can maintain a stable dispersed state of the pigment for a long time.

5.Other areas

Cold polymerized 9 # petroleum resin can also be used to make road sign paint, anti rust paint, and is widely used in ship paint and alkyd paint. In addition, it is also used in fields such as plastics, electronic materials, medical materials, etc., exhibiting excellent physical and mechanical properties and chemical stability. In plastics, cold-polymerized 9# petroleum resin can be used as plasticizer, filler and lubricant to improve the heat resistance, light resistance, wear resistance and aging resistance of plastics.
In summary, cold-polymerized 9# petroleum resin has a wide range of application fields and significant performance advantages, and is a very important chemical raw material.
