CATEGORY

Rosin pentaerythritol ester is a tackifying resin obtained by esterification of rosin and pentaerythritol, belonging to the category of rosin-modified products. As an important polymer additive, it overcomes the shortcomings of natural rosin, such as high acid value, easy crystallization, and poor weather resistance, and features light color, high heat resistance, excellent aging resistance, and good compatibility. This product is usually found in irregular transparent flakes or pale yellow granular solids, and is widely used in hot melt adhesives, pressure-sensitive adhesives, coatings, inks, and the rubber industry.

Function

It is widely used in hot melt adhesives (such as EVA hot melt adhesives and SIS hot melt adhesives) and solvent-based adhesives (such as SBS solvent adhesives). In hot melt pressure-sensitive adhesives (such as label adhesives and tape adhesives), it acts as a primary tackifying resin, imparting excellent initial tack and cohesive strength to the product.

Furthermore, it is also used in woodworking adhesives, binding adhesives, and structural adhesives to improve bond strength and aging resistance.

In the coatings and inks industry, pentaerythritol rosin is used as a modifier. It can improve the gloss, hardness, and chemical resistance of coatings, while also improving film adhesion.

In road marking paints, it increases the abrasion resistance and heat resistance of the film; in offset printing inks, it helps improve the rheological properties and drying speed of the ink.
