### Since the reactivity of MOR

- FREE L 75

- 164 /C

- 411 Adhesive is high, the laminates can generally be further processed in as few as 6 hours, depending on the laminate construction. The chemical curing is generally comp leted within 3 days at 75°F (24 °C), depending on the laminate construction. As always, converters should verify appropriate cure times for their individual application.

The two components of the adhesive are recommended to be used at room temperature of 70 ° F (2 1 ° C) or higher to ensure ease of pumping and homogeneous mixing. The use of heated hoses from the metering pumps to the application point should also be considered

. If the adhesive and coreactant are stored at temperatures below 70 °F (2 1 °C) , each component should be staged in a warmer area and given sufficient time to warm to room temperature. See recommended storage conditions below.

The original viscosity of the mixture can be reduced by preheating the application rollers to a t ypical
t emperature of 120 °

- 1 40  F (50°

- 60  C) . Higher temperatures may be required depending on the line speed , machine configuration, and choice of substrates.

A relatively slow initial increase in viscosity is due to the exothermic reaction of the adhesive immediately after the mixing process and the mechanical influences in the application system.

For short trial runs we recommend preparation of no more adhesive than can be used within 5

- 10 minutes. A high speed stirrer suitable for a homogeneous mixing should be used. However, the use of a meter/mix/dispense device which continuously mixes the adhesive at the chosen ratio, controls the feeding of the application unit, and stops production automatically in case of machine failures, is indispensable for e xtended trials and normal production.

When processing Mor

- 164 / C

- 41 1, the safety rules for working with isocyanates must be observed. The adhesive contains monomeric MDI. See Material Safety Data Sheet for specific details.

Cleaning

The application unit should be cleaned before the adhesive becomes insoluble due to progressive curing, if the machine stops take more than 30 minutes. If the applicable unit and mixing device are combustion proof, they may be cleaned with esters or keton es such as ethyl acetate and MEK. Slower evaporating ester and ketone solvents may also be used.

Several commercially available solvents are safe and effective for flushing and cleaning Mor

- Free adhesive residues from solventless laminators and meter/mix/ dispensing equipment that do not have combustion proof ratings. We recommend contacting either Dynaloy, Inc. (800

- 669

- 5709; www.dynaloy.com ) or Danko Industries (630

- 882

- 6070 ) for cleaning solvent recommendations. Al ways consult the solvent supplier’s MSDS for safety information before use.

- 20  F (2 1 +/

- 10 ° C ) . Opened containers should be used as quickly as possible.

 Store in cool, dry, well ventilated area away from heat and ignition sources. Keep container tightly closed.

 Follow good manufacturing and handling practices.

 Wash thoroughly after handling. W ash contaminated goggles, face shield, and gloves. Professionally launder contaminated clothing before re

- use.

 ATTENTION! Container can be hazardous when empty. Follow label warnings even after container is empty. Do not reuse empty container without p rofessional cleaning.
