Description

Octadecanoic acid, monoester with 1,2,3-propanetriol, polymer with 1,3-diisocyanatomethylbenzene, 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid and 2,2'-(methylimino)bis[ethanol] is a specialized polymeric material designed for advanced industrial applications. This compound matters for its unique combination of properties derived from its stearate and polyurethane/ester-amide hybrid structure, offering versatility in formulation. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of specialty polymers and resin modifiers.

Application

• Resin Modifier and Plasticizer: Used to enhance flexibility, adhesion, and processing characteristics in polyurethane and polyester resin systems.
• Coating Formulations: Serves as a key component in high-performance industrial and protective coatings, improving film formation, durability, and chemical resistance.
• Adhesive and Sealant Production: Imparts tack, cohesion, and environmental stability to adhesive and sealant products.
• Elastomer Synthesis: Acts as a building block or additive in the manufacture of specialty elastomers with tailored mechanical properties.
• Ink and Pigment Dispersant: Functions as a grinding aid and dispersing agent for pigments in printing ink and colorant systems.
• Textile and Fiber Treatment: Utilized in coatings and finishes for textiles to provide water repellency, softness, or specific functional properties.

Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. While specifications vary by grade, our standard industrial-grade material is controlled for key parameters such as viscosity, acid value, hydroxyl value, and solid content. Certificates of Analysis (COA) documenting these and other relevant tests are available upon request to support your quality assurance protocols.

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). This material is moisture-sensitive (hygroscopic); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
