3M 7000028567 Epoxy Potting Compound 270 Clear Part B

Product Description

The 3M 7000028567 is the Base (Part B) component of the Scotch-Weld Epoxy Potting Compound 270 system, a rigid two-part epoxy formulated for potting, sealing, and encapsulation of electrical components. It is mixed at a 1:1 ratio with its corresponding Part A hardener. Once mixed, the compound provides a working life of 70 minutes, giving technicians adequate open time for filling assemblies and enclosures. Handling strength is reached in approximately 3 hours. This 5-gallon container is suited for production or field service operations where volume application is required. Licensed electricians and electronics assembly technicians are the primary installers of this material.

Epoxy Potting Compound 270 is used in residential, commercial, and industrial electrical applications where components must be protected from vibration, moisture, and mechanical stress. Typical use cases include encapsulating circuit boards, transformers, sensors, and junction connections inside control boxes and enclosures. The rigid cure profile makes it well suited for applications where dimensional stability and electrical isolation are required after cure.

Key Features

• 70-minute working life after mixing provides adequate open time for complex pours
• Handling strength achieved in approximately 3 hours after mixing
• Clear cure color allows visual inspection of encapsulated components
• Formulated for potting, sealing, and encapsulation of electrical assemblies
• 5-gallon container volume supports production-scale or high-volume service work

Compatibility

This is the Base (Part B) component of the Scotch-Weld Epoxy Potting Compound 270 two-part system. It must be used with the corresponding Part A hardener. It is designed for potting and encapsulation of electrical components in control assemblies and similar applications.

Installation Notes

This compound should be applied by a qualified technician following standard epoxy handling procedures. Ensure the work area is adequately ventilated and that personal protective equipment including gloves and eye protection is worn during mixing and dispensing. Power down and de-energize all electrical components before potting or encapsulating. Do not exceed the stated working life after mixing, as material beginning to gel will not flow or bond properly.
