Description

Fatty Acids, Tall-Oil Polymers With (T-4)-(Ethyl 3-Oxobutanoato-O1', O3)Bis(2-Propanolato)Aluminum, Isophthalic Acid, Pentaerythritol And Trimethylol Propane CAS NO 212397-89-2 is a specialized, high-performance polymeric complex designed for advanced material formulations. This product matters because it combines the versatility of tall-oil fatty acid polymers with the cross-linking and catalytic functionality of an aluminum alkoxide complex, offering unique rheological and curing properties. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability, adhesion, and chemical resistance.

Application

• High-Performance Industrial Coatings: Acts as a reactive modifier and cross-linking agent in alkyd, polyester, and epoxy resin systems for protective marine, automotive, and industrial maintenance coatings.
• Adhesives and Sealants: Used as a tackifier and curing agent to improve bond strength, flexibility, and environmental resistance in structural and assembly adhesives.
• Composite Materials: Serves as a compatibilizer and surface treatment agent in fiber-reinforced polymer (FRP) composites to enhance interfacial adhesion between fibers and resin matrices.
• Ink Formulations: Employed in specialty printing inks to improve pigment wetting, gloss, and adhesion to various substrates.
• Polymer Additive: Functions as a catalyst or co-catalyst in polymerization reactions and as a property enhancer in plastic and rubber compounds.

Quality Control

Our production of this advanced polymeric complex adheres to strict quality management systems. Each batch is characterized using analytical techniques such as Gel Permeation Chromatography (GPC), Fourier-Transform Infrared Spectroscopy (FTIR), and viscosity measurement to ensure consistent performance and batch-to-batch reproducibility. Comprehensive Certificates of Analysis (COA) detailing key parameters like acid value, hydroxyl value, metal content, and solids content 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/59-77°F). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture uptake and potential oxidation. Keep away from heat, sparks, and open flame.
