Some coumarone resins are viscous liquids, and some are solid, with a light yellow to black color. The relative density is 1.05-1.15; the relative density of the liquid is 1.05-1.07. The softening point is 75~135℃. The glass transition temperature is 56°C. The refractive index is 1.60~1.65. The iodine value is generally 23~39 g I2/100g. It looks like rosin, soluble in organic solvents such as chlorinated hydrocarbons, esters, ketones, ethers, hydrocarbons, most resin oils, nitrobenzene, anilines, etc., insoluble in water and lower alcohols; excellent acid and alkali resistance, water resistance ; Good electrical insulation, aging resistance, and heat resistance; thermoplastic and corrosion resistance; poor light resistance, flammable, and non-toxic. The solid coumarone resin is hard and brittle, looks like rosin, and has thermoplasticity.

use
Mainly used to replace natural resin or esterified rosin, configure insulating coatings and anti-rust coatings, etc., and can also be used in rubber, tires, triangle belts, conveyor belts, paints, inks, waterproofing, hoses and other industries, ceramic adhesives, plastics Plasticizers, etc. Whether it is a solid resin or a liquid resin, the rubber alone has no adhesion; after compounding, the rubber can have good adhesion, including pressure sensitivity or hot melt. Coumarone resin added to rubber can play a role in softening, strengthening, thickening, dispersing, etc., thereby improving the processing performance of the rubber.

In rubber application method: Coumarone resin has good compatibility with rubber and is a solvent-based tackifier, plasticizer and softener. Liquid products are good tackifiers with slightly lower reinforcement; solid products, especially high softening point products, are better reinforcing agents, which can improve the mechanical and physical properties and aging resistance of the rubber compound, but the viscosity is not as good as the liquid fragrance. Bean ketone resin. Dosage of 3-6 parts can dissolve sulfur, help disperse sulfur and carbon black, and prevent scorching. Liquid products are used as tackifiers and plasticizers for natural rubber and synthetic rubber (except butyl rubber), and can also be used as regenerating agents for reclaimed rubber. Solid products can be used as organic reinforcing agents for styrene butadiene rubber, nitrile rubber and neoprene
