film forming temperature of RDP

What is the Minimum Film Forming Temperature of Redispersible Polymer Powder?

The film-forming temperature of an Redispersible Polymer Powder (RDP) is vital in developing the optimal performance of any product being manufactured from it for the construction industry.

This temperature is known as the Minimum Film-Forming Temperature (MFFT) and refers to the temperature at which the polymer particles fuse together and create a smooth, continuous, and crack-free film.

The film is essential for improving durability, flexibility, and performance in a range of cement-based systems.

Sakshi Chem Sciences Pvt. Ltd manufactures and supplies high-performance RDP products that have been specially developed to suit the evolving needs of the construction industry.

Our RDP is specifically developed for use in tile adhesives, self-leveling underlayments, repair mortars, waterproofing systems, and exterior insulation finishes, providing unmatched consistency and reliability.

How is MFFT Important?

If, during cement hydration, the curing temperature is less than the MFFT, the polymer particles do not perform as intended, remaining apart but scattered, not forming or tight coating, thus not enhancing the tensile strength of the mortar or its flexibility.

When the temperature is greater than MFFT, the polymer particles soften and come together to create a continuous film.

 This film binds to the cement hydration products, forming a bridge-like structure within the mortar. In turn, this can provide more stress redistribution within the mortar/resistance to cracks and increase the durability of the finished product.

One of the reasons choosing an RDP with the right MFFT is crucial, especially for polymer-modified mortars, tile adhesives, and insulation systems that require longevity of performance.

How Sakshi Chem Sciences Achieves the Right MFFT?

Our RDP products have specifically been designed to perform at the film-forming temperature that is most suitable under normal curing conditions for construction applications, which is important for forming a uniform and strong film and improving the performance of the mortar.

When optimally matched to the curing conditions, RDP from Sakshi Chem Sciences provides:

  • Greater cohesion and bond strength.
  • Greater flexibility to dissipate stress and minimize cracking.
  • Greater resistance to water penetration and abrasion.

These advantages make the RDP from Sakshi Chem Sciences a preferred choice for high-performance applications such as external wall systems, flooring compounds, and repair products.

Key Advantages of RDP in Construction

The unique quality of the RDP that allows it to form a film at appropriate temperatures offers many potential advantages for modern construction methods.

Flexibility & Crack Resistance – Limit shrinkage cracks in mortars.

Stronger Adhesion – Improves bond strength in tile adhesives and thin-bed systems.

Water Resistance – Improves waterproofing membranes and exterior finishes.

Durability – Improves abrasion resistance for flooring and self-leveling materials.

Workability – Improves smoother dealing with repair and structural mortars.
