### This two component solventless adhesive system is virtually independent of the need for moisture for curing.

The original viscosity of the mixture can be reduced by preheating the application rollers to a t ypical temperature 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 a nd 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 extended trials and normal production.

When processing Mor

- 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 t he adhesive becomes insoluble by 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 ketones such as ethyl acetate and MEK.

Several commerci ally 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. Always consult the solvent supplier’s MSDS for safety information before use.
