Description

Thiourea, Polymer With Formaldehyde is a synthetic resin formed by the polycondensation of thiourea and formaldehyde. This thermosetting polymer is valued for its excellent chemical resistance, particularly to acids and solvents, and its ability to provide durable, cross-linked networks. It serves as a critical raw material for manufacturers in the coatings, adhesives, and plastics industries seeking to enhance product durability and performance under harsh conditions.

Application

• Industrial Coatings & Paints: Used as a cross-linking agent in acid-resistant and chemical-resistant coating formulations for metal, concrete, and industrial equipment.
• Adhesives & Sealants: Acts as a key resin component in high-performance adhesives, especially for bonding materials exposed to corrosive environments.
• Molding Compounds: Employed in the production of thermosetting molding powders for electrical components, knobs, and handles requiring dimensional stability and chemical inertness.
• Textile & Paper Treatment: Utilized in finishes to impart crease resistance, water repellency, and improved durability to fabrics and paper products.
• Flame Retardant Additives: Serves as a component in flame-retardant systems for plastics, textiles, and wood due to its nitrogen and sulfur content.
• Ion-Exchange Resins: Can be modified for use in specialty ion-exchange resins for selective metal recovery or water treatment applications.

Quality Control

Our Thiourea-Formaldehyde Polymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance, including analysis of key parameters such as resin content, viscosity, and curing properties. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment to guarantee compliance with your technical requirements.

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). Keep away from heat sources and open flame. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption and premature curing.
