Quality: white to almost white powder, almost odorless. 1% water suspension is heated to 54 ℃ -78 ℃, the following cooling to 40 ° C, can form a gel, this gel is then heated to 54 ℃ -78 ℃, is still soluble, then the heat reversible gel. Heated to above 80 ℃, to form a resilient gel, this gel to cool before heating (up to 130 ° C), and do not dissolve, as the thermal irreversibility. The glue heating temperature is higher, the longer the gel strength is also insoluble in water and organic solvents, soluble in the pH value of more than 12 lye, formic acid. 
 Purposes: curing agent, gelling agent, stabilizer, thickener
