*These items are provided for general information only. They are approximate values and are not

considered part of a product specification. 

Typical Uses

Adcote 123 plus Coreactant F is recommended for use in laminations requiring high degrees of bond 

strength, age stability, thermal resistance and chemical resistance. Where ultraviolet resistance is of prime 

concern, Adcote 123 plus Coreactant 9L10 would be preferred.

Some typical laminations using Adcote 123 are: 

- Polyester film/polyester film

- Polyester film/metallized polyester film

- Polyester film/treated polyolefin films

- Polyester film/polyvinyl chloride films

- Polyester film/aluminum foil

- Aluminum foil/treated polyolefin films

- Aluminum foil/polyvinyl chloride film

Caution

Laminations containing plasticized PVC films should be evaluated thoroughly to determine the resistance of

the adhesive to plasticizer migration.

Mixing for Use 

Adcote 123 should be mechanically agitated in the drum prior to catalyzing or diluting. Combine 100 parts of

Adcote 123 with 7.0 parts Coreactant F or 5.6 parts Coreactant 9L10 just prior to use. Dilute as desired with

the desired urethane grade solvents and mix thoroughly.

PACKAGING AND

BUILDING MATERIALS 
Adhesive Application

Adcote 123 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 grams of dry adhesive per square meter will generally provide excellent results in

laminations of light gauge substrates. Higher adhesive weights may be required in laminations of heavy 

gauge substrates and/or where high degrees of thermal or chemical resistance are required. 

Drying

Use sufficient temperature and air velocity to assure complete 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 substrates 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 solution adhesives like Adcote 123 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 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 

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.
