What is the starch ether dosage for tile adhesive applications?

For tile adhesive applications, starch ether (HPS) is used primarily for anti-slip and anti-sagging properties. It is mainly applied in ceramic tile adhesives meeting the C1 and C2 standards. HPS powder is effective for bonding large tiles, vitrified tiles, and marble.


The recommended dosage of starch ether is 0.5-1 kg per ton of adhesive. This dosage enhances the bonding capabilities of the tile adhesive. Preventing the tiles or ceramics from slipping even under added weight.


There will be a visible difference in stability between tiles with and without the addition of HPS powder to your formula.

What is a starch ether?

Starch ether is a modified starch compound. It can enhance adhesives by improving adhesion, flowability, and film-forming properties. Finally, resulting in strong and durable bonds.

How long does tile adhesive take to set?

After tile adhesive is applied, it’s better to fix the tiles in 20-30 minutes.

Which is better tile adhesive or cement?

Tile adhesives have some benefits compared with mixed sand cement. Adhesives have good durability and stronger adhesion. With extra impact resistance and waterproofing.

Is starch ether suitable for adhesive applications in a high-temperature environment?

Yes! WOTAIchem’s starch ether maintains its integrity even in high-temperature environments. It can help you ensure reliable bonding performance.
