ADCOTETM 545-80 

Laminating Adhesive

Description and Features

Adcote 545-80 is a solvent based two component polyurethane adhesive with high solid characteristics

excellent heat and chemical resistance. This polyester adhesive in conjunction with various isocyanate

terminated coreactants functions as a laminating adhesive for flexible packaging and industrial applications. 

Adcote 545-80 provides optical clarity and high bond strength. 

Adcote 545-80 adhesive adheres to a wide variety of substrates including cellophane, treated polyolefins,

polyester, polyamide, aluminum foil, paper, metalized and PVDC coated materials, and the treated side of

heat-sealable coextruded films. 

Typical Uses

Adcote 545-80 with Coreactant F is suitable for the lamination of transparent and aluminum-containing 

structures with and without sandwich printing. Principal uses are in flexible materials for food pouches,

vacuum or gas flushed luncheon meats and cheese, coffee pouches, condiment packaging, cable wrap 

laminations, liquid packaging, hygroscopic powders, chemicals and cosmetics.

PACKAGING AND

BUILDING MATERIALS 
Safety, Handling and Storage 

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

closed. 

• Hot organic chemical vapors can suddenly and without warning ignite when mixed with air. Ignition 

can occur at typical elevated temperature process conditions. Please evaluate such processes to 

assure safe handling conditions. 

• Support and ground containers before opening, dispensing, mixing, pouring or emptying. Open with 

non-sparking tools. If container is warm, open bung slowly to release the internal pressure. 

• Wash thoroughly after handling. Wash 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 use heat, sparks, open flames, torches or cigarettes on or near empty containers. 

Do not reuse empty container without professional cleaning. 

• Refer to Material Safety Data Sheet for more information. 

Alcohol and similar materials containing active hydrogen can react with the Adcote 545-80 and Coreactant F

causing inadequate cure. Adcote 545-80 with Coreactant F could potentially interact with other constituents

of the laminated structures. Retained solvents, printing inks, slip additives, film additives, antiblock agents, 

coatings, contaminated solvents as well as the packed product are some of the components that may cause

property changes of the film and/or adhesive. 

Recommended Operating Conditions

Application Method Direct gravure

Application Cylinder 165 - 200 line (65 - 80 line per cm) 

Application Solids 35 - 50% 

Pot Life Static 8 hours approximately 

 Dynamic 24 hours approximately 

Dry Adhesive Weight 1.1 - 2.5 lbs/ream (2 - 4.5 gsm) depending on structure

Drying Web Temperature 150 - 200°F (65 - 93°C) 

Lamination Temperature 125 - 180°F (52 - 82°C) 

Cure Time 5 - 10 days at 70°F (21°C) 

Slitting/Rewinding Time 4 - 8 hours at 70°F (21°C) 

Cleaning Solvent Methyl ethyl ketone, ethyl acetate or other suitable organic solvents. 

Initial bond immediately off the laminator is good. Within 48 hours the bond strength will be sufficient for 

further processing, such as slitting and rewinding. Maximum properties of heat and chemical resistance will 

develop within 5 - 10 days.
