information. Adcote 49

- 164 resin can react or interact with other components of the structure. Retained solvents, slip additives, antiblock agents and contaminated solvents are some of the components that may

cause prope rty changes of the substrates and/or Adcote 49

- 164 resin.

General Information

The initia l color and clarity of Adcote 49

- 164 resin will remain unchanged after outdoor e xposure. In addition, Adcote 49

- 164 resin is resistant to attack by dilute acid and al kali solutions. When mixed with coreactant, the tensile strength and resistance to chemical plasticizers, solvents and water are noticeably improved. The melting temperature range will also increase. With some substrates, the addition of a

coreactant ma y improve adhesion.

High molecular weight po lyester adhesives like Adcote 49

- 164 have a tendency to form a reversible structure in solution with time. This structuring is accelerated when the adhesive is exposed to temperatures below 50°F. The structuri ng is reversible if heat and shear are applied to the adhesive. We recommend placing the container of adhesive in a steam cabinet, allowing venting of the container and heating to 110

- 140°F. After the adhesive reaches the proper temperature, mix the adhe sive in the

container for 1

- 3 hours under moderate shear. Use of a disperser or “Cowles” type blade will shorten the

time needed.

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

review MSDS for hazards asso ciated with the adhesive.

Attempting to redisperse without heat may reduce the apparent viscosity, but not result in a homogeneous mix. Before using the adhesive, check, to make sure that all resin has returned to a true solution and no gels remain.

Dir ections For Use Apply Adcote 49

- 164 resin by any of the conventional methods, including gravure coater, reverse roll coater, knife and spraying. Dilution may be necessary. Apply enough wet coating to deposit

0.1

- 0.3 dry mils (or approximately 2

– 6 dry l b per 3000 square feet) and completely remove the solvents. Laminate with heated nip rolls to provide a minimum glue line temperature of 140°F.

The preferred method for bonding is to coat the more stable substrate, heat the glue to a temperature above

140 °F, and laminate. A heated press can be used for general purpose bonding by employing enough pressure to insure intimate contact between the adhesive and both surfaces, and holding this pressure until the glue line reaches 140°F.

When using Coreactant, u se the amount shown in the Suggested Curatives 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 without. Curing begins after sol vent removal and continues slowly at room temperature. Approximately 7

– 14 days are necessary to complete the cure at room temperature, but a post cure at elevated temperatures can reduce this time.Adcote 49

Pot Life

It i s best not to mix more Adcote 49

- 164 resin and coreactant than will be used in 8 hours. Any mixed solution that is left over should be stored in tightly closed containers and should be used within 3 days. When reusing, we recommend that you combine the old mixed solution with newly mixed solution in the ratio of 25% old and 75% new, and mixed thoroughly.

Safety Precautions

Adcote 49

- 164 resin contains somewhat toxic and/or flammable solvents and suitable handling precautions should be observed. Do not inhale the fumes. Avoid prolonged and repea ted contact with the skin. Eye contact must be prevented. Synthetic gloves, face shields and aprons impermeable to these solvents should be worn when there is possible skin contact. Use NIOSH approved respirators to avoid fumes.
