DOLPHON CY-1114-A 5 kg, yellow epoxy potting resin component A for electrical impregnation and protection, 2-part system, UL94 V-0, 180°C thermal class

DOLPHON CY-1114-A 5 kg is component A (resin) of a two-part, filled epoxy potting and impregnation system for electrical components. The resin offers good penetration behavior, low shrinkage after curing, and is designed for thermal-cycle and water resistance. DOLPHON CY-1114-A must be used together with a compatible system hardener to achieve the required final performance.

Advantages and unique features

• Component A of a 2-part potting/impregnation system (filled, halogen-free epoxy resin)
• Excellent resistance to thermal cycles and good water resistance
• Good electrical properties of the cured system
• Low shrinkage after curing (approx. 0.3%)
• Self-extinguishing system: UL94 V-0 (4 mm), file E317428
• Suitable up to class H applications; thermal class (20,000 h): 180°C
• Good heat dissipation (thermal conductivity after curing: 0.8 W/m·K)
• EN 45545-2 certified (HL levels depending on R22/R23 requirements)

Properties and applications

• Potting and casting: for stators, electrical magnets, transformers, electrical brakes, coils and capacitors
• Impregnation: for windings and electrical components
• Unit preparation (to reduce bubbles): pre-heat the unit at 110–120°C for 3 h, cool down to 40–50°C, then pour slowly
• Mixing: if sedimentation occurs, stir the resin to homogenize; mix with hardener slowly to avoid air entrapment (scrape vessel walls and bottom)
• Mix ratio: 100 : 13 by weight and 100 : 22 by volume (resin : hardener)
• Curing: cures at room temperature; final properties can be reached faster by gelling at room temperature and then curing at 70°C for 3 h

Technical parameters

Storage recommendations

Store the resin (component A) for up to 12 months in original sealed packaging, at a maximum of 30°C, protected from direct sunlight and heat sources. Component A may show crystallization; if so, gently warm the product to about 40°C and homogenize it thoroughly to restore initial properties.
