Q1: What is the primary application of EPIKURE 3115A?
A: EPIKURE 3115A is a polyamide-based curing agent designed for use with epoxy resins in high-performance protective coatings, industrial maintenance systems, and corrosion-resistant linings—particularly where flexibility, adhesion to damp or marginally prepared substrates, and chemical resistance are required.
Q2: How does EPIKURE 3115A compare to conventional aliphatic polyamine curing agents?
A: Unlike fast-reacting aliphatic amines, EPIKURE 3115A offers extended pot life and lower exotherm, enabling easier application in thicker films and improved tolerance to ambient humidity. It also provides enhanced flexibility and impact resistance in the cured film without sacrificing adhesion or barrier properties.
Q3: Is EPIKURE 3115A suitable for use in food-contact or potable water applications?
A: EPIKURE 3115A is not pre-qualified for direct food-contact or potable water applications. Formulators must conduct full regulatory evaluation—including extraction testing and compliance verification against applicable regional requirements—before using it in such end uses.
Q4: What are the recommended storage conditions for EPIKURE 3115A?
A: Store in original unopened containers in a cool, dry place away from direct sunlight and sources of heat or moisture. Prolonged exposure to elevated temperatures or humidity may affect viscosity and reactivity. Once opened, ensure containers are tightly sealed to prevent absorption of atmospheric moisture.
