MOR-FREETM ELM 415A Adhesive/CR 88-101 

ELM Low Monomer Adhesive System

Description and Features

Mor-Free ELM 415A + CR 88-101 is a solventless, two component, polyurethane adhesive system which is

uniquely suitable for laminating metallized film or aluminum to flexible substrates, as well as for laminating

polyester, polyethylene, and other packaging substrates, unprinted or reverse printed. Preheating the

adhesives is not required for most applications. This adhesive system contains less than 0.1% of monomeric 

TDI.

Mor-Free ELM 415A + CR 88-101 may react or interact with other components of laminations. Retained

volatiles (solvents or water), slip additives, antiblock agents and inks are some of the components that may 

cause property changes of the laminated structure. If Mor-Free ELM 415A + CR 88-101 is used on high slip

films (COF < 0.2) or with high slip LDPE/LDPE laminations, then the user must verify that potential film

property changes due to the lamination process and materials, are acceptable for the end use performance

requirements.

Processing

Mor-Free ELM 415A + CR 88-101 must be used on machines which have been specially designed for

solventless laminations. Such equipment allows the adhesive to be fed through a meter/mix/dispense device

and provides web tension controls designed for adhesives with low initial tack. 

As the reactivity of Mor-Free ELM 415A + CR 88-101 is high, the laminates can generally be further

processed after 24 hours. The chemical curing is generally completed within 3 days at ambient temperature.

We recommend the application roll be set at 122° - 140°F (50° - 60°C) or higher, depending on machine 

design and line speed desired. The Mor-Free ELM 415A can be pre-heated to 122o

F (50oC) not to exceed

176o

F (80oC).

PACKAGING AND

BUILDING MATERIALS 

ADHESIVES AND SEALANTS 

Mor
A relatively slow initial increase in viscosity is due to the exothermic reaction of the adhesive 

immediately after the mixing process and the mechanical influences in the application system. 

For short trial runs the adhesive can be batch mixed. We recommend preparation of no more 

adhesive than can be used within 5-10 minutes. A high speed stirrer suitable for a homogeneous 

mixing should be used. However, the use of a meter/mix/dispense device which continuously mixes 

the adhesive at the chosen ratio, controls the feeding of the application unit, and stops production 

automatically in case of machine failures, is indispensable for extended trials and normal production. 

When processing Mor-Free ELM 415A + CR 88-101, the safety rules for working with isocyanates 

must be observed. The adhesive contains less than 0.1% of monomeric TDI. See Material Safety 

Data Sheet for specific details. 

Cleaning 

The application unit should be cleaned before the adhesive becomes insoluble by progressive curing, 

if the machine stops take more than 30 minutes. Where a non-flammable solvent is required to flush 

the mixing and metering units, please consult with your Rohm and Haas representative. If the 

application unit and mixing device are combustion proof, they may be cleaned with esters or ketones 

such as ethyl acetate and MEK. Consult the Material Safety Data Sheet of the solvent supplier for 

safe handling and precautions. 

Several commercially available solvents are safe and effective for flushing and cleaning Mor-Free 

adhesive residues from solventless laminators and meter/mix/dispensing equipment that do not have 

combustion proof ratings. We recommend contacting either Dynaloy, Inc. (800-669-5709; 

www.dynaloy.com), or Danko Industries (630-882-6070) for cleaning solvent recommendations. 

Always consult the solvent supplier’s MSDS for safety information before use. 

Safety, Handling and Storage 

Mor-Free ELM 415A and CR 88-101 can be stored for 360 days in airtight, closed, original containers 

in dry rooms at temperatures of 70° ± 15°F. Opened containers should be used as quickly as 

possible. 

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

tightly closed. 

• Follow good manufacturing and handling practices. 

• 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 reuse empty container without professional cleaning.

• Refer to Material Safety Data Sheet for more information.
