Product Description

Permabond MT3821 is a two-part, 2:1 modified epoxy adhesive for sealing and bonding plastics and metals. The system cures to a soft, flexible material, forming a flexible epoxy bond rather than a rigid joint. It bonds nylon, ABS, polycarbonate, and metals. The controlled two-component format uses a defined mixing ratio, while the flexible cured state supports joints that combine sealing with bonded attachment. Applications include plastic and metal assembly where a soft, flexible epoxy bond is required.
