Description

Tdi/ Linseed Oil/ Pentaerythritol/ Glycerol Polymer CAS NO 68015-31-6 is a specialized alkyd resin polymer synthesized from toluene diisocyanate (TDI), linseed oil, pentaerythritol, and glycerol. This formulation is engineered to deliver a unique balance of flexibility, adhesion, and chemical resistance, making it a critical component in high-performance coating systems. It is primarily required by manufacturers in the industrial coatings, adhesives, and specialty chemical sectors seeking to enhance the durability and protective qualities of their products.

Application

• Primary binder in high-durability industrial and marine protective coatings.
• Key component in corrosion-resistant primers and topcoats for metal substrates.
• Formulation base for high-gloss, weather-resistant architectural paints.
• Resin component in specialty adhesives and sealants requiring flexibility.
• Modifier for printing inks to improve adhesion and film properties.
• Base for wood finishes and varnishes that require enhanced water resistance.

Quality Control

Our Tdi/ Linseed Oil/ Pentaerythritol/ Glycerol Polymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including viscosity, solids content, acid value, and color to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) documenting full specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent moisture absorption and potential property changes. Keep away from heat sources and open flame.
