Description

Tall Oil/ Isophthalic Acid/ Glycerol Alkyd Resin is a specialized synthetic polymer designed for high-performance coating applications. This resin offers a superior balance of chemical resistance, durability, and excellent adhesion to various substrates. It is a critical raw material for formulators in the protective and industrial coatings sectors seeking to enhance product longevity and performance. The compound is identified by the CAS registry number 66071-17-8.

Application

This alkyd resin is engineered for demanding environments where standard coatings may fail. Its primary applications include:

• Protective Industrial Coatings: For machinery, structural steel, and chemical processing equipment requiring resistance to strong acids and organic solvents.
• Marine and Offshore Coatings: Providing excellent protection against saltwater corrosion and harsh weather conditions.
• Automotive and Transportation Finishes: Used in primers and topcoats for trucks, agricultural equipment, and railcars.
• Heavy-Duty Maintenance Paints: For bridges, storage tanks, and industrial flooring systems.
• Appliance and Metal Furniture Coatings: Delivering a hard, durable finish with good color retention.
• Specialty Inks and Adhesives: As a binder component for high-strength formulations.

Quality Control

Our Tall Oil/ Isophthalic Acid/ Glycerol Alkyd Resin is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as acid value, viscosity, solids content, and color to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Containers should be kept tightly sealed when not in use to prevent skinning and contamination.
