Safety, Handling and Storage 

• Store in cool, dry, well ventilated area. 

• 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. 

Other components of, and in, the substrates can react with Mor-Ester 49002-PS. This can result in changes 

of the Mor-Ester 49002-PS as well as the substrates and other components of the structure. It is 

recommended to test the suitability of the Mor-Ester 49002-PS for a particular application before large-scale 

use is undertaken.
