Protecting Structures with a Proven Technology
Used widely in Commercial and Architectural applications across many markets, Si-Rex03 is a state-of-the-art evolution of Silicone Resin Emulsion Paint (SREP) coating technology.
Silicone Resin Emulsion Paint (SREP) was invented in Germany specifically for concrete and masonry substrates. And ranks among the most effective coatings for concrete new and old.
Si-Rex03 builds on the key performance attributes of SREP; active water repellency, functional breathability, resilience to UV exposure and the elements for a coating that delivers a superior and longer lasting solution.
The result. Si-Rex03 protects the substrate thereby adding to the structural integrity to help extend the service life of concrete infrastructure.
Delivering Long Lasting Protection
The promise is simple; use a proven technology to create a durable, long lasting coating with performance to match. Performance that provides optimal water repellency – yet high breathability for entrapped moisture to escape (outgas) for long term structural integrity.
Owners, specifiers, developers and property custodians can count on Si-Rex03 to provide real solutions for structural protection, long service life with minimal maintenance needs and colors that remain strong and true year in, year out.
Reduced maintenance needs and longer repainting intervals deliver a tangible lower “cost of life” coating solution.
Dynamic Product and Looks
Klaas Coatings brings a no-compromise approach to protective coatings for concrete.
Only premium raw materials are used in the production of Si-Rex03 under tight QC guidelines.
At the core, silicone resins that offer high permeability to water vapor and CO2, low water absorption, self-cleaning functionality, a Mineral Matte appearance for long service life.
For excellent depth of color, superior fade resistance and durability to weathering only inorganic pigments are used.
Si-Rex03 provides durable structural protection, long service life with minimal maintenance needs and colors that remain strong and true year in, year out.
With its unique Mineral Matte finish, and ability to be tinted to match many old school and traditional colors, Si-Rex03 is the perfect coating system for the preservation of historical buildings, structures and sites.
Silicone Resin Emulsion Paint (SREP) has been used on over a million structures just in Europe alone, a number being iconic historical structures with some dating back over hundreds of years.
The self-cleaning surface, along with use of biocides to minimize mold and mildew growth, assist in keep the look and feel of these structures over time.
