Description

Fatty Acids, Tall-Oil, Polymers With Glycerol, Phthalic Anhydride And Styrene is a synthetic resin derived from the polycondensation of tall oil fatty acids, glycerol, phthalic anhydride, and styrene. This versatile alkyd-type polymer is engineered to provide excellent film-forming properties, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and ink industries seeking to enhance product durability and performance. The CAS number for this compound is 68915-15-1.

Application

This specialized polymer resin is designed for high-performance applications where robust film properties are essential. Its primary uses include:

• Industrial and Protective Coatings: As a key binder in air-drying and baking enamels for machinery, agricultural equipment, and metal structures, offering excellent weather and corrosion resistance.
• Printing Inks: Used in the formulation of overprint varnishes and specialty inks that require high gloss, rub resistance, and fast drying times.
• Adhesives and Sealants: As a tackifying and reinforcing resin to improve adhesion strength and flexibility in construction and automotive sealants.
• Wood Finishes: A component in varnishes and stains for furniture and flooring, providing a durable, clear protective film.
• Modifier for Other Polymers: Used to plasticize or improve the compatibility and processing of other polymer systems.

Quality Control

Our production of this polymer resin adheres to stringent quality management protocols. Each batch is characterized for critical parameters including acid value, viscosity, solids content, and color to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We operate in compliance with ISO 9001 standards, and our quality system is designed to meet the specific requirements of the coatings and chemical manufacturing industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong alkalis and incompatible organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent skinning or changes in viscosity.
