Packaging, storage, safety instructions of Tylose MH 2000 YP2:
As with all organic powdered substances, cellulose ethers pose a dust explosion hazard. 
To avoid flammable dust-air mixtures, the risk of dust formation and accumulation must be minimized. 

Avoid fire sources such as open flames, hot surfaces, sparks, electrical disturbances. 
Tylose begins to decompose at around 200˚C. 
The flash point is greater than 360˚C. 

Tylose MH 2000 YP2 for use in construction
Restrictions on use : There is no information available on applications that are not advised

Tylose burns easily and the fire can spread.
Tylose can be stored for a long time if stored in a closed container or in Tylose MH 2000 YP2s original packaging, in a dry place at room temperature. 
For high-viscosity types, slight loss of viscosity may occur after long-term storage (more than 1 year). 
Tylose absorbs water from humid air. 
The opened container must be resealed.
