Laminating Adhesive - Preliminary TDS

Description Adcote L76-178 is the isocyanate-terminated polyester urethane component of a two-component adhesive system that requires the use of coreactant CR-384 to achieve full properties.

Adcote L76-178/CR-384 adhesive provides high bond strength and a high level of heat and chemical resistance. The adhesive system is used in multi-layer structures that require extended shelf life for packaging aggressive foodstuffs.

The cure rate of laminations made with Adcote L76-178 adhesive is dependent on the temperature and relative humidity of the storage or holding area. The adhesive does not require hot room storage although elevated temperatures accelerate the cure time and improves process throughput.

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 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 the internal pressure.

 Wash thoroughly after handling. Wash contaminated goggles, faceshield, 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.
