Paints: varnish can be made by petroleum resin mixed with various drying-oil and different coating can be formed by adding various resin/rosin and pigments. It also improves hardness of film, water proofing resistance to acid and alkali, and reduces the price.
Rubber: Petroleum resin is suitable as an additive to national and synthetic rubber making easily the molding operations and increasing hardness and elasticity. Owing to the hardness, strength and anti-ageing, it is specially used as softening agent of SBR rubber and for the production of hose, tape ad tire etc.
Adhesive: Petroleum resin has moderate adhesive property, being able to used as compounding agent of adhesive and adhesive tape. In order to improve waterproofing of water soluble adhesive,I also can be used as compounding agent for plywood ,wall paper and leather adhesives. Owing to solidification shrinking percentage is small , it can be used in foundry.
Printing Ink: Petroleum resin is water-proofing, wearability, weather fastness. So it can be used for making inks.
Others: Petroleum resin has excellent stability to heat ,weather fastness,so it can be used for making traffic paint and this resin has some unsaturation test so it can be used for making upper-coating-agent of paper and additive of plastic etc. Standard specification :Product name: Petroleum Resin | Products type: PR1------140 | |||
