H.B. Fuller FH7026

H.B. Fuller FH7026 is a two-part, room-temperature-curing acrylic adhesive. This material is designed to meet the requirements for structural bonding in electronic assemblies. It cures rapidly at room temperature, and the cure times can be reduced with the addition of mild heat to the bonded assemblies. This product also provides excellent adhesion and is flexible.

Applications & Uses

Compatible Substrates & Surfaces
Application Instructions

1. Bonding surface area should be clean and free of any fluxes, residues, dust or any other contaminants.
2. Use gloves to minimize skin contact.
3. Application to the substrates should be made as soon as possible. Larger quantities and / or higher temperatures will reduce the working time.
4. Keep assembled parts from moving during cure. The bond should be allowed to develop full strength before subjecting to any service load.
5. Remove uncured adhesive
