Description

Resorcinol-Formaldehyde Resin is a synthetic thermosetting phenolic resin produced by the condensation reaction of resorcinol and formaldehyde. This compound is valued for its excellent adhesion, high-temperature resistance, and superior water resistance compared to other phenolic resins. It is a critical raw material for manufacturers in the rubber, adhesive, and composite industries seeking to enhance product durability and performance under demanding conditions.

Application

As a bonding agent and tackifier in rubber compounding, particularly for tire cord adhesion and belt skim compounds.
As a cross-linking co-agent in wood adhesives and laminates, providing waterproof bonds.
As an impregnating resin for fiberglass and carbon fiber reinforcements in high-performance composites.
In the formulation of foundry sand binders for metal casting applications.
As a modifying resin in abrasive products and friction materials like brake pads.
For the production of flame-retardant coatings and insulating materials.

Quality Control

Our Resorcinol-Formaldehyde Resin is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance characteristics such as gel time, viscosity, and solid content. Certificates of Analysis (COA) detailing batch-specific results 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 product is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture which may affect performance.
