Description

Ppg-12/Smdi Copolymer CAS NO 9042-82-4 is a specialized polyurethane prepolymer derived from polypropylene glycol and methylene diphenyl diisocyanate. This versatile copolymer is valued for its excellent film-forming properties, flexibility, and compatibility with a wide range of formulations. It is primarily utilized by manufacturers in the personal care, coatings, and adhesive industries seeking to enhance product performance and durability.

Application

• Hair Styling Products: Acts as a primary film-forming agent and fixative in hair sprays, gels, and mousses, providing strong hold with good flexibility and low tack.
• Skin Care & Sunscreen Formulations: Used as a water-resistant film former in day creams, sunscreen lotions, and BB creams, improving substantivity and skin feel.
• Nail Care: Serves as a key ingredient in nail polish and enamel formulations to enhance chip resistance, gloss, and adhesion.
• Industrial & Protective Coatings: Imparts flexibility, chemical resistance, and durability in coatings for textiles, plastics, and metals.
• Pressure-Sensitive Adhesives (PSAs): Modifies tack and peel strength in adhesive tapes and labels.
• Printing Inks: Used as a binder to improve adhesion and rub resistance on various substrates.

Quality Control

Our Ppg-12/Smdi Copolymer is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency in viscosity, solids content, isocyanate value, and other critical parameters. A Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications and relevant industry standards for cosmetic and industrial use.

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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture absorption, which can affect product performance.
