Caution must be taken because of the flammability of the solvents used in the adhesive. Please

review MSDS for hazards associated with the adhesive.

Attempting to redisperse without heat may reduce the apparent viscosity, but not result in a

homogeneou s mix. Before using the adhesive, check, to make sure that all resin has returned to a true

solution and no gels remain

Directions For Use

Apply Adcote 1640 E resin using any of the conventional methods, including gravure coater, reverse roll

coater, knif e and spraying. Dilution may be necessary. Apply enough wet coating to deposit

0.15

- 0.25 dry m ils (or approximately 2

- 6 lb /3000 sq. ft.) and completely remove the solvents.

The preferred method for bonding is to 1.) coat the more stable substrate, 2) heat so the glue line is 325  F

minimum, and 3.) bond. A heated press can be used for general purpose bonding by employing enough

pressure to ensure intimate contact between the adhesive and both surfaces, and holding this pressure until

the glue line reaches 325°

- 375  F.

When usin g Coreactant F, use the amount shown in the Typical Properties section as a guide. The

optimum level of coreactant should be determined experimentally for each particular end use. Coating with

coreactant is handled in the same manner as coating without c oreactant. Curing begins after solvent

removal and continues slowly at room temperature. Approximately 7

- 14 days are needed to complete the

cure at room temperature, but a post cure at elevated temperatures can reduce this time.

Pot Life

Do not mix more Adcote 1640 E resin and coreactant that will be needed in 8 hours. Any mixed solution that

is left over should be stored in tightly closed containers and used within 3 days. When reusing, we

recommend combining the old mixed solution with the newly mixed solution at a ratio of 25% old/75% new.

Mix thoroughly.

Safety Precautions

Adcote 1640 E resin contains somewhat toxic and/or flammable solvents, and suitable handling precautions

should be observed. Do not inhale the fumes. Avoid prolonged and repeated skin contact. Eye contact

must be prevented. Wear synthetic gloves, face shields and aprons impermeable to these solvents

whenever there is a possibility of skin contact. Use NIOSH approved respirators to avoid fumes.
