Tile adhesive open time

The Influence of Cellulose Ether on

the Open Time of C1 Class Tile Adhesive

Tile adhesive is a material composed of cementitious materials, admixtures, aggregates, fillers, and additives, mixed by professional equipment. It is packaged as single-component or dual-component.

This article verifies the influence of cellulose ether, specifically its viscosity and dosage, on the open time of C1 class tile adhesive through testing.

1. Experimental Base Formulation

2. Experimental Results

3. Conclusion

The experiment shows that lower viscosity cellulose ethers perform better; and a relatively higher dosage of cellulose ether leads to higher open time values.
