The Minimum Film-Forming Temperature (MFFT) of redispersible polymer powder (RDP) is a critical parameter that determines the temperature at which the polymer particles can coalesce to form a continuous, uniform, and crack-free film. This property is essential for ensuring the optimal performance of RDP in various construction applications, particularly in cementitious systems and polymer-modified mortars.
Celotech, a leading global supplier of high-performance RDP, offers a comprehensive range of redispersible polymer powders designed to meet the diverse needs of the construction industry. Their products are widely used in tile adhesives, exterior insulation and finish systems (EIFS), self-leveling underlayments, repair mortars, and waterproofing membranes, delivering enhanced flexibility, durability, and crack resistance.
When the temperature during cement hydration is below the MFFT, the polymer particles remain dispersed and fail to form a continuous film. In this state, the RDP particles are distributed intermittently within the cement mortar, limiting their ability to improve the mortar’s performance. However, when the temperature exceeds the MFFT, the polymer particles soften and coalesce, forming a cohesive film that integrates seamlessly with the cement hydration products. This film acts as a bridge within the mortar matrix, effectively absorbing and transferring stress, which helps to inhibit the formation and propagation of cracks.
Celotech’s RDP products are engineered with an optimal MFFT, ensuring reliable film formation under typical curing temperatures in construction applications. This makes them ideal for use in polymer-modified mortars, thin-bed adhesives, and thermal insulation systems, where performance and durability are critical.
To achieve effective film formation, it is crucial that the MFFT of the RDP is lower than the curing temperature of the mortar. This ensures that the polymer can form a uniform film structure, distributed evenly between the cement hydration products. The presence of this film enhances key properties of the mortar, including improved cohesion, increased flexibility, and superior resistance to cracking, water penetration, and abrasion.
Celotech’s RDP solutions are specifically formulated to enhance the workability, adhesion, and durability of construction materials, making them ideal for demanding applications such as external wall systems, flooring compounds, and structural repair solutions.
