AMITROPRO®
Starch ethers for construction materials
AMITROPRO® is our range of starch ethers developed for modern dry-mix formulations in the construction industry. Designed for cement- and gypsum-based systems, it enhances workability, open time and sag resistance at low dosage levels. By partially replacing cellulose ether, it supports cost-efficient formulations while contributing to a reduced carbon footprint.
AMITROPRO® is used in dry-mix formulations supporting rheological optimization, water retention and controlled setting behavior. Typical applications include
- Cement-based tile adhesives
- Plasters and skim coats
- Masonry mortars
- Gypsum-based construction materials
- Self-levelling compounds and concrete systems
- Shotcrete and pumping aids
- Board production
Key benefits
- Extended open time for improved adjustability
- Optimized workability and anti-sag behavior
- Reliable quick-set initiation
- Partial replacement of cellulose ether
- Reduced thickener costs
- Stable quality and consistent performance
- Lower carbon footprint compared to other starch ethers
AMITROPRO® supports improved workability and open time in tile adhesive formulations, allowing for more controlled application and reliable tile positioning under practical site conditions.
Starch ethers like AMITROPRO® improve workability and water retention for stable processing and consistent on-site performance.
AMITROPRO® enhances the processing behaviour of gypsum-based systems by supporting smooth mixing and application, contributing to consistent setting characteristics and surface quality.
Benefits & value
AMITROPRO® starch ethers are tailored for mineral-bound construction materials where rheological control is critical. Even at very low concentrations, they significantly influence consistency, water retention and processing behavior.
In tile adhesives, plasters or skim coats, open time and non-sag properties define application quality. AMITROPRO® supports extended working time while maintaining dimensional stability. This balance improves on-site handling and reduces correction work.
Our development builds on AGRANA’s long-standing expertise in modified starches for technical applications. We combine polymer know-how with practical formulation experience to deliver performance that integrates seamlessly into existing systems.
Technical properties
AMITROPRO® improves rheological behavior in hydraulic binder systems. It increases open time and supports faster setting initiation compared to standard types.
The starch ether structure enhances viscosity build-up and contributes to improved anti-sag properties. Formulators can partially replace cellulose ether while maintaining required performance levels.
Compatibility with common aggregates and additives enables flexible formulation design. The product range complements the established AMITROLIT® portfolio and extends formulation options for demanding construction applications.
Sustainability
AMITROPRO® is based on renewable raw materials. Through targeted modification and efficient dosage, it contributes to lower overall material usage and supports reduced carbon footprint in dry-mix systems.
By enabling partial substitution of synthetic thickeners, it helps align technical performance with evolving sustainability requirements in the construction sector.
