DOLPHON CB-1114-A 25 kg, epoxy potting resin component A for impregnation and electrical protection, 2-part filled system, self-extinguishing UL94 V-0, 180°C thermal class

DOLPHON CB-1114-A 25 kg is component A (resin) of a two-part, filled epoxy potting system for impregnating and protecting electrical parts. When mixed with a compatible hardener, it forms a self-extinguishing protective casting with good electrical properties, low shrinkage and excellent thermal-cycle resistance. DOLPHON CB-1114-A is used for potting and impregnating windings, transformers, coils, capacitors and other electrical components.

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 (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 components requiring good penetrating behavior
• Mix ratio: 100 : 13 by weight and 100 : 22 by volume (resin : hardener)
• Pot life: depends on the hardener (e.g., 80–110 min at 25°C with hardener C(a)-1114-B, 100 g sample)
• Process guidance: pre-heat the unit (110–120°C for 3 h), cool down to 40–50°C, then pour slowly to help minimize trapped air
• 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 resin and hardener components 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.

FAQ

1) Can DOLPHON CB-1114-A be used on its own?
No. It is component A of a 2-part system and must be mixed with a compatible hardener to cure and reach final properties.

2) What is the DOLPHON C(a)-1114 system used for?
For potting and impregnating windings, transformers, coils, capacitors and other electrical components.

3) What mixing ratio is recommended?
100 : 13 by weight and 100 : 22 by volume (resin : hardener).

4) What is the pot life after mixing?
It depends on the hardener; for hardener C(a)-1114-B, 80–110 minutes at 25°C is stated (100 g sample).

5) Is the system self-extinguishing?
Yes, UL94 V-0 is stated for 4 mm thickness.
