Hysol ® 9433 
You may print this page for your file
Epoxy Adhesive 

Description 
Dexter Hysol 9433 is a fast cure, medium viscosity toughened epoxy resin formulation recommended for industrial
adhesive, small potting and laminating applications where excellent structural, mechanical and electrical properties are
required. This two-part adhesive exhibits good wetting, cures at room temperature and develops strong, low shrinkage
bonds to most materials including optical fibers, glass, ceramics, most metals and many rigid plastics. It has excellent
stability over a wide temperature range. Fully cured Hysol 9433 is a durable electrical insulator with good physical
properties, plus resistance to water, weather, ozone and oxygen, petroleum solvents, lubricating oils, jet fuels, gasoline,
alcohol, salt solutions, mild acids and alkalis and many other organic and in organic compounds. 

Recommended Substrates: Composites, metals, glass, ceramics, thermoset polyester, many plastics and wood products.

Color White Light Yellow Cream 
Viscosity, poise 1240 -2240 650 - 1650 - 

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. 
Part A Part B

By Volume 2 1 

Pot Life @77°F ( 20 grams): 25 – 30 minutes 

Application 
Mixing - Bulk : Combine Part A and Part B in the correct ratio and mix thoroughly. THIS IS IMPORTANT! Mixing the
adhesive just prior to use is recommended. Heat buildup during or after mixing is normal. Do not mix quantities
greater than one pound (1lb) as dangerous heat buildup can occur. Mixing smaller quantities will minimize the heat
buildup. 

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

Application: Bonding surfaces should be clean and dry. For optimum surface preparation, consult Dexter Hysol'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 room temperature (77°F). Hysol 9433 will achieve handling strength
after ten (10) minutes at 140°F. (Note: this can vary with different bond configurations). Hysol 9433 can also be fully
cured in 30 minutes at 180°F. Other times and temperatures (250°F is a suggested maximum) can be used depending on
the application. 

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.
