Description

Formaldehyde, Polymer With 1,3-Benzenediol, Sodium Salt is a synthetic phenolic resin, specifically a sodium salt of a resorcinol-formaldehyde condensate. This specialty polymer is valued for its strong adhesive and binding properties, as well as its reactivity in cross-linking applications. It serves as a critical intermediate and functional additive in industries requiring high-performance resins, such as tire manufacturing, wood bonding, and friction material production.

Application

• As a tackifying resin and reinforcing agent in the formulation of rubber compounds for tire cord adhesion and industrial rubber goods.
• As a key resin component in the production of high-performance wood adhesives, such as those used in laminated veneer lumber (LVL) and finger-jointing.
• As a binding agent in the manufacture of friction materials for automotive brake pads and clutch facings.
• As a modifier and cross-linking agent in foundry sand binders and other thermosetting resin systems.
• In the formulation of specialty coatings and sealants requiring enhanced chemical resistance and durability.
• As an intermediate in the synthesis of other advanced phenolic resins for composite materials.
