DRD96240-300254 Self-Curing Encapsulant Epoxy Resin, H-C Grade Heat-Resistant Electrical Insulation Component
Key Features
Heat resistance rating is H-C class
Product Introduction
Excellent heat resistance, high resin system viscosity with no sagging, excellent adhesion, superior hardness, extended workability time, and minimal shrinkage upon curing.
Performance parameters
96240-300254 is an epoxy extrusion-type potting compound manufactured using advanced processing technology, based on high-molecular-weight epoxy resin and a curing agent. This product is widely suitable for encapsulating indoor medium- and high-voltage electrical insulation components—including applications like securing motor rotor necks and winding slots, sealing automotive motor solder joints, bonding transformers, insulating column-type insulators, covering terminal bushings, encasing switch components, and encapsulating current and voltage transformers—through manual extrusion or vacuum-assisted extrusion methods, as well as conventional pouring techniques.

Operating Procedures
Encapsulation with Epoxy Process
Epoxy resin exhibits strong adhesive properties and thixotropic behavior, eliminating the need for baffle slots in rotor windings.
Traditional Atmospheric Pressure Potting and Casting
For manufacturing insulating components—such as encapsulating motor rotor necks or potting wire channels—pressure-free, squeeze-type dispensing can be used. First, weigh Component A and Component B in a ratio of 100:16, then thoroughly mix them until uniform (mixing time depends on the weight; ensure complete blending). Once mixed, the material can either be applied directly or transferred into a dedicated squeeze bottle for later use. After dispensing, move the product to an appropriate rack or oven and allow it to gel and cure under standard atmospheric pressure.
Curing conditions
Curing conditions: Surface dry at 32°C for 12 hours, reach initial hardness after 24 hours, and achieve full curing within 7 days.
Activation Period: Use the mixture within 1 hour after mixing. Prepare only the amount of adhesive you need based on your actual requirements.
Packaging format
Storage Conditions
Component A: 5 kg
Component B: 0.8 kg
Use safely
When stored under dry conditions at room temperature, the unopened A and B components have shelf lives of 3 months each.
Important Notes
Unhardened materials must not come into contact with food or food utensils, and precautions should also be taken to prevent direct skin contact, as some individuals with sensitive skin may experience adverse reactions. It is generally recommended to wear impermeable rubber or plastic gloves, along with appropriate eye protection. After each work session, thoroughly wash your skin with soap and warm water—avoid using solvents. Ensure the workplace is well-ventilated, and refer to the product’s Material Safety Data Sheet for specific safety guidelines.
