Xolutec® is an innovative coating technology that combines the durability of NCO-cement hybrids with the easy handling of 2-component epoxy systems. It offers strong chemical resistance, mechanical strength, and flexible crack-bridging in a user-friendly format.
From Complexity to Convenience – The Smarter Coating Solution
For over 50 years, isocyanate–polyol–water–cement systems (NCO-cement hybrids) have been used in construction coatings where high mechanical stress and chemical exposure are expected. These systems offer an excellent balance of performance and cost, thanks to their unique combination of urethane, urea, and cement domains. However, traditional 4-component systems pose challenges in logistics and application, including sensitivity and short pot life.
Xolutec® technology was developed to retain the proven performance of NCO-cement hybrids while simplifying application. By using a calcium hydroxide slurry emulsified in a polyol as the isocyanate hardener, Xolutec® maintains similar chemistry but enables easier packaging and handling comparable to 2-component epoxy systems.
This innovation also allows greater flexibility in tuning toughness and elasticity, making crack-bridging systems possible. Xolutec® is already used in wastewater treatment, industrial flooring, parking decks, and as a durable topcoat. Additional applications are in development and expected to launch soon.
Key Properties
- Simple 2-component system like epoxy – but without odor or blushing
- Hard (up to 80 Shore-D) yet not brittle
- Excellent cost-performance ratio
Unique Chemistry
A proprietary blend of complementary chemistries results in a high-performance material:
- A polyurea network forms through the simultaneous reaction of isocyanates, water, and an inorganic binder – similar to Ucrete technology
- The interface between resin blocks and inorganic fillers is carefully optimized
- This creates a dense organic-inorganic hybrid material with exceptional properties:
- Highly cross-linked polymer matrix
- Uniformly embedded inorganic components
- Enhanced overall performance across key metrics
Performance Advantages
- Balanced pot life and curing profile:
- 30-minute pot life
- Tack-free after 4 hours
- Ready for overcoating in 8 hours - Flexible formulation options:
- Cost-effective aromatic isocyanates (with yellowing/chalking)
- UV-stable, non-yellowing aliphatic isocyanates - Scratch-resistant surface with low dirt pick-up
