Description

Anhydride And Tall Oil is a versatile chemical intermediate derived from tall oil, a by-product of the kraft pulping process. This product matters for its role as a reactive building block in the synthesis of resins, polymers, and other high-value industrial materials. It is primarily needed by manufacturers in the coatings, adhesives, and plasticizer industries seeking sustainable and cost-effective raw materials.

Application

• As a key reactant in the production of alkyd resins for surface coatings and paints.
• In the formulation of adhesives and sealants, contributing to improved flexibility and adhesion.
• As a modifier and intermediate in the synthesis of plasticizers for PVC and other polymers.
• In the manufacturing of corrosion inhibitors and lubricant additives.
• As a raw material for epoxy curing agents and other thermosetting polymers.
• In the production of printing inks and overprint varnishes.

Quality Control

Our Anhydride And Tall Oil is produced under strict quality management protocols to ensure batch-to-batch consistency and performance. The product undergoes rigorous testing for key parameters such as acid value, viscosity, and color. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) after opening to maintain stability and prevent degradation. Keep away from heat, sparks, and open flame.
