Petroleum resin is suitable for the heat capacity of road marking paint. It can enhance the toughness, hardness and adhesion of coatings, and form a smooth finish, and by adding additives, the resin is always in a state of stability in the four seasons, and rosin resins miscibility good. In the high-grade paint compound, can make the paint film forming water, UV resistant, chemical resistant properties, and the appearance of the brightness and drying are improved obviously.
Road marking paint made of amyl petroleum resin has the prominent characteristic:
Light color; good fluidity; high abrasion; filler dispersion, not uniform settlement of
Strong weather resistance; the drying speed is fast; stain resistance and
2 adhesive of
In the adhesives and sealants industry, C5 petroleum resin as tackifier resin has occupied an important position. Which is the largest amount of hot melt adhesive and pressure-sensitive adhesive, I produced the C5 petroleum resin is suitable for petroleum resin hot melt adhesive and pressure-sensitive adhesive. They are SIS, SBS, SEBS and SEPS etc., styrene polymer, natural rubber, synthetic rubber and EVA has good compatibility with tackifying resin, natural (terpenes, rosin and its derivatives) compatibility is good, the performance of the adhesive have different degrees of improvement. In recent years, C5 petroleum resin by the peeling high adhesive strength, good viscosity, fast adhesion performance is stable, moderate melting viscosity, good heat resistance, good compatibility with polymer matrix, and low prices, began to gradually replace the natural resin tackifier (resin and terpene resin) and took a significant position.
Characteristics of C5 petroleum resin in hot melt adhesive:
Good fluidity, can improve the wettability of
the main material Good sticky, with prominent initial adhesion properties of
Excellent resistance to aging of
Light color
Transparent, low odor, low volatile
In hot melt adhesive can be used alone, PRS? -A series as tackifying resin, but also with other tackifying resin mixed use, to enhance certain properties of hot melt adhesive.

3 tire rubber I produced the C5 petroleum resin is a kind of widely used in tire and rubber mixing aliphatic petroleum resin, and the natural rubber (NR), synthetic rubber, polyethylene, SIS, SEBS, EVA has good compatibility with tackifying resin, natural (such as: terpenes, rosin and its derivatives) compatibility also good. In the rubber mixing can be made: the tackifier, reinforcing agent, softening agent, filler, etc..
In the rubber mixing properties of
With excellent viscosity
Can play a softening, reinforcing effect in the process of processing, improve the stretching and spalling resistance of
Significantly improve the students stick, but does not affect the curing time and curing of
To avoid the adhesion of
fill material Color depth is moderate

Thiourea dioxide is insurance powder substitute products, with strong reduction, good thermal stability, storage characteristics of convenient transportation. The product can be used as a reducing agent, bleaching bleaching agent, plastic stabilizer, organic synthesis and antioxidant effects of photographic materials agent etc.. In the printing and dyeing, papermaking and other industries has been widely used. No pollution in the process of use.

-1,4- is a cis polybutadiene rubber abbreviation, its molecular formula is (C4H6) n. Polybutadiene rubber is synthetic rubber regular structure formed by the polymerization of butadiene, the CIS structure content above 95%. According to the different catalysts, can be divided into nickel, cobalt, titanium and rare earth (nd) of polybutadiene rubber. Polybutadiene rubber is the second largest synthetic rubber after styrene butadiene rubber. Compared with the natural rubber and styrene butadiene rubber, vulcanized after its cold resistance, abrasion resistance and flexibility is particularly excellent dynamic load, less heat, aging resistance is good, easy and natural rubber, neoprene or nitrile rubber and. Polybutadiene rubber is especially suitable for the manufacture of automobile tires and cold products, but also can create the buffer material and all kinds of rubber overshoes, adhesive tape, adhesive tape and sponge rubber etc.
