Product Details

Compared with the traditional cement mortar, gypsum mortar has the advantages of fire prevention, heat insulation, sound insulation, flame retardant, light weight, humidity adjustment, no hollowing and cracking, etc. In recent years, gypsum mortar has developed rapidly. Mellutel cellulose ether endows gypsum mortar with the following characteristics:

The hydroxypropyl methyl cellulose ether hpmc is the essential condition for thin bed technology for tile adhesive.

Can be used as retarder, water retention agent, thickener and binder.

Characteristics of ceramic tile adhesive

1. improve the plasticity and water retention of pressed ceramic tile mortar, improve the adhesive force of ceramic tiles, and prevent pulverization.

2. it is easy to mix, operate and spread without sticking the knife.

3. good anti hanging effect; Good initial adhesion.

4. long opening time, good wettability and long adjustable time.
