Hydrogenated carbon nine petroleum resin products are odorless and odorless, with excellent thermal stability, good weather resistance, and wide compatibility. Used in SBC series hot melt pressure sensitive adhesive, EVA series hot melt adhesive, pressure sensitive self-adhesive adhesive, PP film modifier and other products. It is also used as rubber tackifier and enhancer, dry oil modifier, paper sizing agent, ink color development agent and connecting material.
Carbon nine petroleum resin emulsion emulsified by solvent and emulsifier can be miscible with neoprene emulsion to make exterior paint with strong adhesion and weather resistance; anti-rust coating; mixed with emulsified asphalt to make waterproof coating; used as casting Binders can improve the casting yield.
Petroleum resin advantages:
Petroleum resin is a newly developed chemical product in recent years. Due to its advantages of low price, good miscibility, low melting point, water resistance, ethanol resistance and chemicals, it can be widely used in rubber, adhesives, coatings, paper, ink, etc. Multiple industries and fields.
The difference between petroleum resin and other thermosetting compounds is that it does not emit low-molecular compounds during the curing process, and it has a high degree of condensation in the liquid state. The curing time is through direct addition. For an unmodified system, the shrinkage is tiny. Generally, it is about 2%, which means that the volatility between the molecules is very small.
Petroleum resin was cast into a standard mold, the volume of the standard mold cavity and the volume of the sample after molding were measured, and the volume shrinkage of the sample was calculated.
Test method: Disassemble the mold and take out the resin sample after molding, and then use calipers to accurately measure the cavity size (including length, width, and height) of the mold frame of the mold, accurate to 0.01 mm. )Hang the resin sample on the balance with copper wire or hairline and weigh it in the air, then put the sample into 20 distilled water, weigh it in water, and weigh the accuracy to 0.001 g
