Hydroxypropyl Methylcellulose (HPMC) for Tile Adhesive Applications
Hydroxypropyl Methylcellulose (HPMC) is a high-performance cellulose ether widely used in tile adhesive formulations to enhance key mortar properties such as water retention, workability, adhesion strength, anti-slip performance, and open time. The addition of HPMC improves mixing consistency, reduces cracking and sagging, and ensures reliable bonding of tiles on both walls and floors.
At Keyoung Chemical, we provide a range of HPMC grades designed for different tile adhesive performance needs, backed by application-oriented technical support and formulation services tailored to your local raw materials and standards.
What Is HPMC in Tile Adhesive?
Hydroxypropyl Methylcellulose (HPMC) is a water-soluble, non-ionic cellulose ether widely recognized in construction chemistry. In tile adhesive systems, HPMC acts as:
- A water retention agent that slows the evaporation of mixing water to support full cement hydration.
- A rheology modifier, improving consistency, spreadability, and anti-slip behavior.
- A bond strength enhancer, helping tiles adhere firmly to substrates.
- An open time extender, allowing sufficient working time during installation.
These properties are essential for producing C0, C1 and C2 standard tile adhesive mortars with reliable performance and durability.
Keyoung Tile Adhesive HPMC Grades
Keyoung Chemical offers a comprehensive range of HPMC grades for tile adhesive applications, each engineered to meet different performance requirements:

U-3040 is a medium-high viscosity product characterized by high water retention and good workability, making it suitable for ordinary C0 standard tile adhesives. It effectively improves the workability, thickening, and adhesion of mortar, ensuring reliable performance in standard applications.
Recommended Dosage:
2 – 3.5 kilograms per ton of mortar.
U-3070 — High Viscosity HPMC
U-3070 is a high viscosity hydroxypropyl methyl cellulose. It is a colorless, odorless, fine powder and is a non-ionic, water-soluble cellulose ether.
Applications & Advantages:
U-3070 possesses high water retention and excellent adhesion properties, which significantly enhance the bonding and adhesion strength of tile adhesive. It improves the consistency and workability of the mix, facilitating easier handling and increasing construction efficiency. This product is ideal for standard C0 tile adhesives.
Recommended Dosage:
2 – 3 kilograms per ton of mortar.
U-3110 — Low Viscosity / Anti-Sag HPMC
U-3110 is a low viscosity hydroxypropyl methyl cellulose. It is a colorless, odorless, fine powder and is a non-ionic, water-soluble cellulose ether.
Applications & Advantages:
U-3110 is a modified cellulose ether with excellent anti-sagging performance. Its low viscosity makes it particularly suitable for pasting large ceramic tiles on vertical surfaces without slippage. It provides superior workability and an extended opening time, making it a high-quality cellulose ether suitable for C1 and C2 standard adhesives.
Recommended Dosage:
2 – 3 kilograms per ton of mortar.
U-3120 — Modified HPMC
U-3120 is a high viscosity hydroxypropyl methyl cellulose. It is a colorless, odorless, fine powder and is a non-ionic, water-soluble cellulose ether.
Applications & Advantages:
U-3120 is a modified cellulose ether used in cement-based tile adhesives. It features excellent anti-slip properties and is specially formulated as an anti-sagging and thickening agent. It improves mortar workability, enhances open time and application smoothness, and increases water retention and lubricity for easy troweling.
Recommended Dosage:
2 – 3 kilograms per ton of mortar.
U-3130 — Modified HPMC
U-3130 is a medium viscosity hydroxypropyl methyl cellulose. It is a colorless, odorless, fine powder and is a non-ionic, water-soluble cellulose ether.
Applications & Advantages:
U-3130 is a modified cellulose ether that offers extremely high anti-slip performance, making it an ideal anti-sagging/thickening agent for tile adhesives. It enhances mortar workability, open time, and surface smoothness. Additionally, the thickened adhesive is less prone to penetrating tile joints, reducing sealant usage and improving bond strength.
Recommended Dosage:
2 – 3 kilograms per ton of mortar.
U-3150 — High Viscosity Long Open Time HPMC
U-3150 is a high viscosity hydroxypropyl methyl cellulose. It is a colorless, odorless, fine powder and is a non-ionic, water-soluble cellulose ether.
Applications & Advantages:
U-3150 is a high-viscosity, modified cellulose ether renowned for its excellent anti-slip properties and outstanding open time. The high viscosity makes it suitable for construction conditions requiring longer working times and larger coverage areas. It provides excellent workability and anti-sag performance, qualifying it as a high-quality cellulose ether for C1 and C2 standard tile adhesives.
Recommended Dosage:
2 – 3 kilograms per ton of mortar.
