Epoxy Adhesive

Description
Hysol 9430 is a modified epoxy adhesive that attains structural properties after room temperature cure. This two-part adhesive is formulated to give very high peel strength coupled with excellent shear strength. Bonds are permanently flexible and resist water, salt spray and many common industrial fluids.  The tough, flexible nature of this adhesive makes it useful for bonding dissimilar substrates and for assemblies requiring bondline thickness up to one-tenth inch.

Handling
Mixing : This product requires mixing two components together just prior to application to the parts to be bonded. Complete mixing is necessary.

Application
Mixing: Combine Part A and Part B in the correct ratio and mix thoroughly. THIS IS IMPORTANT! Heat buildup during or after mixing is normal. Do not mix quantities greater than ten pounds (10 lbs.), as excessive heat buildup can occur.  Mixing smaller quantities will minimize the heat buildup.

Applying: Bonding surfaces should be clean and dry and properly prepared. For optimum surface preparation, consult Dexter's Bulletin " Preparing the Surface for Adhesive Bonding". The bonded parts should be held in contact  until the adhesive is set. It is not necessary to maintain fixturing for the entire cure schedule, only until handling strength is achieved. Hyandling strength of 500 psi is achieved in 6-8 hours @ 77°F.

Curing: Hysol 9430 can be cured for 5 days at room temperature (77°F). Curing temperatures up to 180°F can also be used to reduce cure time. For example, 1 hour @ 180°F will give complete cure.

Cleanup: It is important to remove excess adhesive from the work area and application equipment before it hardens. Denatured alcohol and many common solvents are suitable for removing uncured adhesive. Consult with your supplier's information pertaining to the safe and proper use of solvents.
