C O NVE R T I NGAdcote L 49-158 February 2010 Page 2 of 2 Adhesive Application Adcote L 49-158 can be applied by gravure, smooth roll, or reverse roll techniques. The adhesive is generally applied to the less porous, more stable substrate.

Adhesive Weight Approximately 3.2–4.8 g/m 2 (2-3 pounds per ream) of dry adhesive will generally provide excellent results in laminations of light gauge substrates. Higher adhesive weights may be required in laminations of heavy gauge substrates, rough or absorbent surfaces and/or where high degrees of thermal or chemical resistance are required.

Drying Use sufficient temperature and air velocity to assure co mplete solvent removal. Oven temperatures in the range of 93-121°C (200-250°F) are generally suitable.

Laminating Combining Laminate to the second substrate using heated pressure-nip rollers at a temperature high enough to assure complete wetting of the secondary substrate. A minimum temperature of 70°C (150°F) is recommended; however, temperatures approaching 176°C (350°F) may be required to obtain optimum adhesive performance in laminations of heavy gauge substrat es or where adhesion is of prime importance.

Bond immediately off the laminator is fair. Slitting 4 to 8 hours after lamination is acceptable. Maximum thermal and chemical properties will develop within 7-14 days. For high performance applications post curing at elevated temperatures of 48-66°C (100-150°F) is recommended.

High molecular weight polyesters that are used in so lution adhesives like Adcote L 49-158 have 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 structuring is reversible if heat and shear is applied to the adhesive. We recommend placing the container of ad hesive in a steam cabinet, allowing venting of the container and heating to 110-140°F. After the adh esive reaches the proper temperature, mix the

adhesive 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 associated 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.
