Henkel Hysol EA 9395 High Temperature Epoxy Paste Adhesive - Quart

Mixing:
Combine Part A and Part B in the correct ratio and mix thoroughly. IMPORTANT: Heat buildup during or after mixing is normal. Do not mix quantities greater than 450 grams as dangerous heat buildup can occur causing uncontrolled decomposition of the mixed adhesive. TOXIC FUMES CAN OCCUR, RESULTING IN PERSONAL INJURY. Mixing smaller quantities will minimize the heat build-up.

Applying:
Bonding surfaces should be clean, dry and properly prepared. For optimum surface preparation, consult the Hysol Surface Preparation Guide. The bonded parts should be held in contact until the adhesive is set. Handling strength for this adhesive will occur in 24 hours @ 77°F/25°C, after which the support tooling or pressure used during cure may be removed. Since full bond strength has not yet been attained, load application should be small at this time.

Curing:
This adhesive may be cured for 5 days @ 77°F/25°C or 1 hour @ 150°F/66°C to achieve normal performance.

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

This material will normally be shipped at ambient conditions, which will not alter our standard warranty, provided that the material is placed into its intended storage upon receipt. Premium shipment is available upon request.

Handling

Mixing:

This product requires mixing two components together just prior to application to the parts to be bonded. Complete mixing is necessary. The temperature of the separate components prior to mixing is not critical, but should be close to room temperature (77°F/25°C).

Mix Ratio by Weight: 100 (Part A) : 17 (Part B)

Note: Volume measurement is not recommended for structural applications unless special precautions are taken to assure proper ratios.

Pot Life:

(450 g mass) 95 - 100 minutes @ 77°F/25°C. Method - ASTM D2471 in water bath.
