Description

Amines, Rosin (CAS 61790-47-4) are a specialized class of amine derivatives derived from rosin, a natural resin obtained from pine trees. These compounds are valued for their unique combination of the adhesive and film-forming properties of rosin with the reactivity and basicity of amines. They serve as critical intermediates and performance additives in several high-value industrial sectors. Key industries that utilize these materials include adhesives, printing inks, coatings, and paper sizing, where they enhance product performance and stability.

Application

• Adhesive Formulations: Act as tackifiers and curing agents in hot-melt, pressure-sensitive, and epoxy adhesives, improving bond strength and thermal stability.
• Printing Inks: Used as grinding aids and dispersants in pigment preparations for inks, improving color development and print quality.
• Protective Coatings: Function as corrosion inhibitors and adhesion promoters in industrial and marine coatings.
• Paper Sizing Agents: Key components in alkaline paper sizing to improve water resistance and printability of paper and paperboard.
• Asphalt Modification: Employed as adhesion promoters and anti-stripping agents in asphalt pavements and roofing materials.
• Foundry Resins: Serve as core binders and hardeners in sand casting processes for metal fabrication.
• Surfactants and Emulsifiers: Act as intermediates in the synthesis of specialty surfactants for various industrial applications.
