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

DOLPHON CB-1114-A 5 kg is component A (resin) of a two-part epoxy potting system for electrical protection and impregnation. It is intended for producing durable, self-extinguishing protective castings and for protecting assemblies where good electrical properties, low shrinkage and thermal-cycle resistance are required. DOLPHON CB-1114-A is used together with a compatible system hardener to achieve the required mixed-system performance.

Advantages and unique features

• Two-part epoxy potting system (component A: resin)
• Excellent resistance to thermal cycles and good water resistance
• Good electrical properties
• Low shrinkage after curing
• 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 0.8 W/m·K after curing)
• EN 45545-2 certified (HL levels depending on R22/R23)

Properties and applications

• Potting and casting: for stators, electrical magnets, transformers, electrical brakes, coils and capacitors
• Impregnation and protection: for windings and electrical components requiring good resin penetration
• Environmental resistance: designed for water resistance and thermal-cycle performance
• After curing: hardness Shore D 80–90 and shrinkage approx. 0.3%
• Process notes: cures at room temperature; properties can be reached faster by gelling at room temperature and then curing at 70°C for 3 h (process-dependent)

Technical parameters

Storage recommendations

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

FAQ

1) Is DOLPHON CB-1114-A ready to use on its own?
No. It is component A of a 2K 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/casting stators, transformers, coils and capacitors, and for impregnating windings and electrical components.

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

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

5) Does the system meet flammability requirements?
Yes, the system is self-extinguishing and UL94 V-0 is stated for 4 mm thickness.
