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, 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.

Adcote 522 is moisture sensitive. Containers should not remain open for an extended period of time.
