Description

Ammonia, Urea, Formaldehyde Polymer CAS NO 27967-29-9 is a synthetic thermosetting resin belonging to the class of amino resins. This polymer is valued for its excellent adhesive properties, water resistance, and ability to form durable, cross-linked networks upon curing. It is a critical industrial material primarily required by manufacturers in the woodworking, construction, and coatings industries for producing high-performance composite materials and surface finishes.

Application

• Wood Adhesives: Primary binder in the production of plywood, particleboard, medium-density fiberboard (MDF), and laminated veneer lumber (LVL).
• Surface Coatings: Key component in industrial and automotive paints, lacquers, and varnishes to enhance hardness, chemical resistance, and gloss.
• Foundry Sand Binders: Used as a binding agent in core and mold-making processes within the metal casting industry.
• Textile Finishing: Employed to impart wrinkle resistance, shrinkage control, and durable-press properties to fabrics.
• Paper Saturation: Improves wet strength, stiffness, and grease resistance in specialty papers and paperboard.
• Friction Materials: Acts as a resin binder in brake linings and clutch facings for the automotive sector.

Quality Control

Our Ammonia, Urea, Formaldehyde Polymer is manufactured under strict process controls to ensure batch-to-batch consistency and performance. Quality is verified against key parameters including viscosity, solids content, gel time, and free formaldehyde content. Certificates of Analysis (COA) documenting these specifications are available for every shipment 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 ambient temperature (15-25°C). Avoid exposure to extreme heat or freezing conditions to prevent changes in viscosity or premature curing. Keep away from strong acids and bases.
