Epoxy potting compounds for potting and encapsulation
Potting compounds are at the frontline of electronics assembly, delivering effective protection in challenging environmental conditions while improving mechanical strength and offering high electric insulation.
Epoxy potting compounds are designed to work in temperatures of less than 180 degrees and offer the highest mechanical strength. Our range of applications includes protection from acids, alkalis, gasoline and solvents.
At Veeyor Polymers, we have special compounding techniques that allow the use of halogen-free and ROHS compliant pre-polymers to achieve UL94 V-0 flame retardancy properties.
Transformers are exposed to hot temperatures and high voltage. To function properly, they need component protection. Veeyor polymers manufacture a full line of formulated epoxy resin used in transformers and transformer components

Filling an electronic assembly with an epoxy potting compound can be challenging Especially, selecting the wrong epoxy mixture can lead to a dangerous exothermic reaction. An exothermic reaction can produce enough heat to damage the components that the epoxy was intended to protect. Excess shrinkage can create stress on components or create cracks in the epoxy when cured. VEEFILL 303 F / H 160 system is a cold curing epoxy system, it is mainly used in electronic potting applications where low exotherm in required
Key Features
- Anti-settling properties
- Class B insulation
- Low exothermic reaction
- Long potlife and superior performance
