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

considered part of a product specification. 

Typical Uses

Laminations that require a high order of bond strength, age stability, thermal resistance and chemical

resistance. Typical laminations for which it is suited are: 

 Polyester Film/Polyester Film

 Polyester Film/Aluminum Foil 

Mixing for Use

Combine 100 parts Adcote 76R67 with 4 parts Coreactant F or 3.2 parts of Coreactant CT just prior to use.

Dilute as desired with the recommended urethane grade solvents. 

Coating

Apply compounded adhesive to the less porous, more stable film, such as the polyester, nylon or foil. 

Gravure, roll coat or reverse roll coat techniques are suitable. 

Apply 3.5-4.0 pounds dry solids per ream (3,000 square feet) for thinner films. The coating weight must be

adjusted accordingly for increases in film thickness to obtain maximum flame retardancy.

Drying

Use temperatures and air velocities needed for complete solvent removal. An exit web temperature of

150-180°F normally is sufficient.

PACKAGING AND

BUILDING MATERIALS 
Combining

Combine with second web using heated pressure nip rollers at 175-250°F for light weight webs. For thicker 

films combining temperatures of 300-350°F. 

Bond immediately off the laminator is fair. Within 24 hours the lamination will cure to a good machinable

bond. Maximum chemical and thermal properties will develop within 7-14 days. For high performance 

applications post curing at elevated temperatures of 120-150°F is recommended.
