Methacrylate Adhesive
Description
Dexter Hysol H4000 is a non-sagging, two component, room temperature curing, 10:1 mix ratio, methacrylate adhesive system. H4000 is formulated to reach fixture time rapidly. This adhesive forms resilient bonds and maintains its strength over a wide range of temperatures. H4000 is suitable for bonding a variety of substrates with a minimum of surface preparation for the most demanding bonding applications.
Recommended Substrates: PVC, polycarbonate, acrylic, ABS, stainless steel, epoxy coated metal and FRP
Features

Handling and Application

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.  Once mixed, H4000 should achieve a uniform color.  This is important!  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 H4000, 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.  
Hysol H4000 is flammable.  Keep containers tightly closed after use.  Keep away from heat, sparks, and open
flames.
Storage
Hysol adhesives should be stored in a cool, dry place when not used for a long period of time. The shelf life for H4000 is one year from date of manufacture when stored at 40oF and six months when stored at room temperature or 77oF. Exposure above room temperature will reduce shelf life.
