Epoxy Adhesive 

 Description
HYSOL® 609 is an exceptional epoxy formulation recommended for lower temperature or wet industrial bonding applications where fast curing is required.  This ultra clear, two part, low viscosity system mixes easily at room temperature.  It is suitable for high performance structural bonding applications requiring a combination of very fast room temperature cure, low shrinkage, excellent mechanical properties.  Fully cured Hysol 609 is an excellent electrical insulator and provides superior resistance to vapors and gases, water, galvanic action, petroleum fuels, salt solution and many other organic and inorganic compounds.

Recommended Substrates: metals, phenolic plastics, polyester, glass and glass fabrics, hardboards and forestry products, ceramics, rubber, masonry materials and other construction materials.

Handling
Mixing:  This product requires mixing two components together just prior to application.  Complete mixing is necessary.  The temperature of the separate components prior to mixing is not critical, but they should be close to room temperature.

Application
Mixing - Bulk: Combine Part A (resin) and Part B (hardener) in the correct ratio (1:1) and mix thoroughly until the color and consistency are uniform.  Ratios given above can be used for measuring larger amounts.  Mixing the adhesive just prior to use is recommended.  Heat buildup during or after mixing is normal.  Do not mix quantities greater than 1/2 pound as dangerous heat buildup can occur causing uncontrolled decomposition of the mixed adhesive.  Mixing smaller quantities will minimize the heat buildup.

Mixing - Cartridges: Place cartridge in proper dispenser.  To begin using a new cartridge, remove the cap and dispense a small amount of adhesive, making sure both parts A  B are extruding.  Attach nozzle and dispense approximately 1-2" before applying onto the part to be bonded.  Partially used cartridges should be stored with the mixing nozzle attached.  To reuse, remove and discard the old nozzle, attach the new nozzle, and begin dispensing.

Application:  Bonding surfaces should be clean and dry. For optimum surface preparation, consult Dexter's Bulletin  Preparing the Surface for Adhesive Bonding.  Once the adhesive is applied, the bonded parts should be held in contact until the part has developed handling strength.  It is not necessary to clamp the parts unless movement during cure is likely.

Cure:  Complete cure is obtained after 24 hours at 77°F.  HYSOL 609 will achieve handling strength after 10 minutes at 77°F (note: this can vary with different bond configurations).

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