ADCOTETM 842/CR 842D 

Laminating Adhesive

Description 

Adcote 842/CR 842D is a two component solvent-based, high performance adhesive system. Adcote 

842/CR 842D is recommended for use in high temperature applications such as autoclave, steam

sterilization, microwave, boil-in-bag and hot film packaging applications. This adhesive system has

excellent adhesion properties to aluminum foil, ceramic coated films and a variety of film substrates. The 

adhesive system has high initial bonds and offers excellent heat and chemical resistance properties. 

Application 

Adcote 842/CR 842D is suitable for the lamination of transparent film and aluminum foil containing 

structures. This adhesive system is used in applications requiring high temperature exposure and product 

resistance including autoclave, steam sterilization, and specific retort packaging applications where an 

aliphatic coreactant-based system is required. Adcote 842/CR 842D is especially recommended for

lamination of SiOx- and AlOx-coated barrier films. Adcote 842/CR 842D can be used in microwave 

packaging applications with films specified for this application. 

Adcote 842/CR 842D may react or interact with other components of laminations. Retained volatile 

components (such as solvents or water), slip additives, anitblock agents, and inks are some of the 

components that may cause property changes of the laminated structure. 

Our Technical Service is ready to supply all the relevant information regarding the correct use of our

adhesive.

food legislations, please contact our Technical Service for food contact status. 

The information provided relates to this specific product. We believe this information to be accurate and 

reliable as of this date. We recommend you make your own determination on the suitability of this product 

for your particular application. 

Safety Information 

Material Safety Data Sheets (MSDS) are available for all Rohm and Haas products. These sheets contain 

important information that you may need to protect your employees and customers against any known 

health and safety hazards associated with our products. We recommend that you obtain copies of our 

MSDS from your local Rohm and Haas technical representative before using our products in your 

facilities. We also suggest that you contact your suppliers of other materials recommended for use with 

our products for appropriate health and safety precautions before using them. 

Typical Processing Conditions 

Application Method: Direct or Reverse Gravure or Smooth Roller 

Application Cylinder: 130 lines per inch (Gravure) 

Application Solids: 30 – 40 % NVM. 35% - 37.5% NVM is recommended. Dilute with “urethane grade” 

ethyl acetate, acetone and MEK. 

Dry Adhesive Weight: 2.0 – 3.0 lb/ream (3000 square feet) 

Drying Web Temperature: 150 - 180oF 

Lamination Temperature: 140 – 200oF 

Cure Time: Must be post cured @ 115 - 130oF for 3 days for optimal heat resistance and end use 

properties. 

Pot-Life: Approximately 8 Hours at 35% NVM. Pot life is a function of environmental conditions of 

temperature and humidity. 

Safety, Handling and Storage 

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

closed. 

• Hot organic chemical vapors can suddenly and without warning combust 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 internal pressure. 

• Wash thoroughly after handling. Wash contaminated goggles, face shields, 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. 

CR 842D is moisture sensitive. Containers should not remain open for an extended period of time. Flush 

with nitrogen gas before resealing to prevent reaction with atmospheric moisture.
