Non-crytallizing ester of rosin

Non-crytallizing ester of rosin is a modified ester of rosin which offers an excellent combination of oxidation and crystallization resistance. This product functions as a tackifier for SBR, natural rubber, butyl rubber, ethylene-vinyl acetate and other polymers. It can be delivered in flaked and solid forms. Formulated in solvent-based and water-based adhesives, it exhibits no tendency to crystallize. It meets the requirements of the Code of Federal Regulations, Title 21, under the following section: 175.105 Adhesives; 176.210 Defoaming Agents Used in the Manufacture of Paper and Paperboard; 177.2600 Rubber Articles Intended for Repeated Use.



1.Soluble in Aromatic and aliphatic hydrocarbon solvents and chlorinated solven ts. Soluble at 50% or higher solids in ethanol, n-propanol and isopropanol. Insoluble in ethylene glycol, propylene glycol and water.

2.Compatible with SBR, natural rubber, butyl rubber, chlorinated rubber, neoprene, EVA, EEA, SIS and SBS copolymers, polyethylene, polypropylene, acrylic polymers, phthalate and polyester plasticizers, alkyds and hydrocarbon resins.


Water-based adhesives, flooring adhesive.

Pressure sensitive, sealant, hot melt and rubber compounding applications.

Welding aids and cleaning agents,

Film coating adhesives,

Alcohol soluble printing inks and paints.


Solvent based construction adhesives including carpeting, flooring, framing and tile applications where good tack and stability are required.


1. Flaked forms in multiwall bags, 25kgs net. Depending on storage and climatic conditions, Fintac2331 is subject to remassing, but is readily broken up. Remassing is not considered a basis for rejection of the flaked product.

2. Solid form in galvanized steel rosin drums, 225 kg net, or molten in bulk.

Although flaked Fintac2331 provides excellent shelf stability compared with other flaked resins, prolonged storage should be avoided due to potential effect on performance.
