Description

Ancamine 350A is a high-performance, modified aliphatic amine curing agent widely used in epoxy resin systems. Its primary value lies in providing excellent low-temperature cure characteristics, good flexibility, and enhanced chemical resistance to the final polymer. This product is essential for formulators and manufacturers in the coatings, adhesives, sealants, and composites industries seeking to optimize the physical properties and processing of their epoxy-based products.

Application

• As a curing agent for epoxy resins in high-performance industrial and marine protective coatings.
• Formulating flexible adhesives and sealants for construction, automotive, and aerospace applications.
• Production of composite materials, including laminates and tooling, where good mechanical properties are required.
• Flooring and civil engineering applications, such as self-leveling floors and grouts.
• Electrical potting and encapsulation compounds due to good electrical insulation properties.
• Modifier in other amine-based curing agent systems to improve toughness and low-temperature performance.

Quality Control

Our Ancamine 350A is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including amine value, viscosity, and color to meet our rigorous internal specifications. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee product integrity for your formulation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance. Keep away from heat, sparks, and open flame.
