Product Description
Loctite® Speedbonder® H3300 is a highly thixotropic, two component, room temperature curing, 1:1 mix ratio, methacrylate adhesive system. H3300 is formulated to provide fixturing strength within 6 - 12 minutes. This adhesive forms resilient bonds and maintains its strength over a wide range of temperatures. H3300 is suitable for bonding a variety of substrates with a minimum of surface preparation.
Recommended Substrates:
- PVC
- Polycarbonate
- Acrylic
- ABS
- Stainless Steel
- FRB
Directions for Use:
-
Mixing: It is highly recommended that either meter mix equipment or cartridges with static mix nozzles be used to properly ratio and dispense the adhesive.
- For hand mixing, combine Part A and Part B in the correct ratio and mix thoroughly. Mix less than 100 grams at a time!
- Once mixed, H3300 should achieve a uniform color. Heat buildup during and after mixing is normal.
To reduce the likelihood of exothermic reaction or excessive heat buildup, mix less than 100 grams at a time. Mixing smaller amounts will minimize heat buildup.
- Applying: Bonding surfaces should be clean, dry, and free of contamination.
- Extensive surface preparation is not required for H3300, and good bonds can be formed on most substrates after a solvent wipe.
- To assure maximum bond strength, surfaces must be mated within the adhesive's open time.
- Use enough material to completely fill the joint when parts are clamped.
- Curing: Parts should remain undisturbed during the interval of time between the material’s open time and fixture time. After the fixture time is achieved the material has reached handling strength. Temperature below 55°F will slow the cure; above 85°F will accelerate cure rate.
- Clean Up: It is important to clean up excess adhesive from the work area and application equipment before it cures. Denatured alcohol and many common industrial solvents are suitable for removing uncured adhesive.
- Speedbonder H3300 is flammable. Keep containers tightly closed after use. Keep away from heat, sparks, and open flames.
