Rosin glycerides G-90

Rosin glycerides are glycerol esterifications of stabilized rosin, which have good stability and polymer solubility, and are widely used in pressure-sensitive adhesives and adhesive industries.

Technical indicators: color number (Gardner) ≤4, acid value mgKOH/g≤10, softening point (R&B global method), °C 90-95 °C

Rosin pentaerythritol ester P-100

Rosin pentaerythritol ester is made of rosin esterified pentaerythritol, which has the characteristics of light color, excellent heat resistance and weather resistance. It is used in adhesive and rubber industries.

Technical indicators: color number (Gardner) ≤4, acid value mgKOH/g≤20, softening point (R&B global method), °C 98-102 °C

Malinic Acid M-130

Marinic acid resin is a light yellow transparent solid obtained by using resin as raw material, adding with maleic anhydride, and esterifying with glycerol or pentaerythritol. This kind of resin is mainly used in the paint and coating industry, and can be applied to phenolic paints by thermal polymerization with vegetable oil, and can be added to polyester, nitro and polyurethane paints to improve the hardness, brightness and sandability of paint wax.

Technical indicators: color number (Gardner) ≤4, acid value mgKOH/g≤25, softening point (R&B global method), °C 125-130 °C
