Description

Fatty Acids, Tall-Oil, Polymers With Glycerol, Isophthalic Acid And Pentaerythritol is a synthetic resin derived from tall oil fatty acids, a renewable resource, polymerized with polyols and isophthalic acid. This compound is valued for its excellent film-forming properties, chemical resistance, and versatility as a binder or modifying resin. It is primarily needed by manufacturers in the coatings, adhesives, and ink industries seeking high-performance, sustainable raw materials. The product is supplied under CAS No. 68188-66-9.

Application

• Alkyd Resin Modifier: Used to enhance flexibility, drying time, and durability in industrial and architectural alkyd coatings.
• Protective Coatings: Serves as a key binder in corrosion-resistant primers and finishes for metal substrates.
• Adhesive Formulations: Imparts tack and adhesion strength in pressure-sensitive and structural adhesives.
• Printing Inks: Acts as a resinous component to improve gloss, rub resistance, and pigment wetting.
• Overprint Varnishes: Provides a protective, glossy topcoat for packaging and printed materials.
• Industrial Maintenance Paints: Used in heavy-duty coatings for machinery, equipment, and structural steel.

Quality Control

Our production of this polymer resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. A Certificate of Analysis (COA) detailing these specifications is provided with each shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep away from heat sources and open flame. For long-term storage, consider blanketing with an inert gas such as nitrogen.
