Product overview
Polymer modification.
Practical performance.
Atopas® is TIPOO Group's registered trademark for redispersible polymer powder products and complements the Atocell™ cellulose portfolio.
In mortar systems, Atopas® RDP improves workability and flexibility and enhances hydrophobicity, durability, tensile strength and anti-bending performance. The catalog identifies broad use in cement-based tile adhesives, thermal insulation systems and self-leveling flooring compounds.
Key benefits
Performance built into
the mortar matrix.
Mechanical strength
Improves mortar strength, including impact and abrasion resistance.
Workability
Supports easier mixing, application and finishing.
Flexibility
Increases flexibility and helps reduce cracking during curing.
Resistance
Provides resistance to heat, water, freeze-thaw cycles and ageing.
Durability
Enhances durability and hydrophobicity and reduces the bibulous rate of mortar.
Benefits summarized from the TIPOO Group Catalog 2025, RDP section.
