Key Advantages

Improved Workability

Enhances the smoothness and ease of application for dry mix mortars,like tile adhesives.
Sag Resistance

Prevents mortar’s slippage during vertical installation, ensuring precise alignment.
Better Water Retention

Helps maintain moisture in the mix, supporting proper cement hydration.
Consistent Performance

Ensures stable rheology and application properties across different formulations.
Synergistic Effect with Cellulose Derivatives

Maximizes thickening, anti-sag, and open time when used together.

Q&A

Q1: What is the main purpose of starch ether in mortars?

A: Starch ether improves workability, water retention, and sag resistance in mortars like tile adhesives and putty, ensuring better application and finish quality.
Q2: Can starch ether be used alone?

A: It can be used alone, but the best results are achieved when combined with cellulose derivatives for enhanced performance.
Q3: In which products is starch ether commonly applied?

A: It is widely used in dry-mix cement-based mortars, tile adhesives, skim coats, and other building materials.
