Is the highest viscosity HPMC the best choice for tile adhesive?

HPMC (Hydroxypropyl methyl cellulose) is an important ingredient in cement-based tile adhesives because of its unique properties that enhance the performance of cementitious materials. It acts as a thickener, controlling the processability of the adhesive while improving its adhesion and water retention properties. As the construction industry continues to evolve, HPMC has become even more important in meeting the high standards and requirements of modern construction practices.

HPMC is an important additive to enhance the viscosity of tile adhesive. Generally, the higher the viscosity of the HPMC solution, the better the viscosity of the tile adhesive and the better the adhesion to the substrate.

We all know that tile adhesive has different grade like C0, C1 and C2. Starting with the most basic classifications, C1 and C2, these denote 'normal' and 'improved' adhesives, respectively. Normal adhesive (C1) is a general-purpose adhesive suitable for a wide range of applications where no specific conditions or stresses are expected. Improved adhesive (C2), on the other hand, signifies an enhanced performance adhesive that typically provides higher adhesion strength and flexibility, making it suitable for more demanding applications, such as large-format tiles or challenging environmental conditions.

Most of companies will choose the highest viscosity HPMC (100,000--200,000 mPa?s) for tile adhesives, but is the highest viscosity HPMC the best choice for tile adhesive?

We all know highest viscosity HPMC has excellent adhesion strength, but HPMC not only play one role in tile adhesive, it also has following advantages.

1. Good water retention

2. Improve the bonding strength

3. Excellent workability

4.?Extended opening time

5. Good slip resistance

6. Good shrinkage resistance

When you choose the highest viscosity HPMC, of course it offers excellent adhesion strength, but you may have noticed that it's opening time get shorter, so you will not have enough working time.

That's why modified products is the best choice when you want have all the properties.

Shandong Huiguang Technology Development Co.,Ltd?is a one of the most professional cellulose ether manufacturer?in China, we are the most famous company in the field of modified products.
