Description

Araldite M CAS NO 3101-60-8 is a high-performance, light-sensitive epoxy resin hardener, specifically a modified aromatic amine. This compound is critical for formulating advanced thermosetting epoxy systems that require excellent mechanical strength, thermal stability, and chemical resistance. It is essential for manufacturers and formulators in the composites, adhesives, and electrical insulation industries seeking reliable curing agents for demanding applications.

Application

• Composite Manufacturing: Curing agent for high-strength epoxy matrices in aerospace, automotive, and wind turbine components.
• Structural Adhesives: Key component in high-performance industrial and construction adhesives requiring durable, heat-resistant bonds.
• Electrical & Electronic Encapsulation: Used in potting and encapsulation compounds to protect sensitive components from moisture and thermal shock.
• Tooling and Molding: Formulation of durable epoxy tooling masters, patterns, and molds for composite lay-up and casting.
• Protective Coatings: Basis for chemical- and abrasion-resistant industrial floorings, tank linings, and marine coatings.
• Civil Engineering: Modifier for epoxy-based grouts, repair mortars, and concrete bonding agents in infrastructure projects.
