PROTECTOSIL® provides long-term protection of valuable structures like building facades, bridges, or centuries-old monuments.

PROTECTOSIL® is the brand name for silane-based products protecting and preserving building structures. Made up of “protect” and “sil(anes)”, PROTECTOSIL® is one of Evonik’s best-known brands and has been used in building protection for over 35 years. These products are commonly used in construction and infrastructure projects. From the opera house in Sydney, Australia, to the Times Square in New York City: many well-known buildings around the world are protected with PROTECTOSIL® from Evonik.

Highly efficient level of protection 
Silanes with their unique chemical structure ensure that mineral substrates, such as concrete, brick, or natural stone, retain their unsurpassed durability and longevity without impairing function or aesthetics. Effectively protected, the buildings don’t need to be constantly repaired or even rebuilt. This extends service life and significantly reduces maintenance and repair costs. It also benefits the environment.

The PROTECTOSIL® portfolio offers the right solution for every requirement: it includes water-repellent agents, easy-to-clean solutions and graffiti protection for walls and façades, agents for corrosion protection of reinforced concrete structures, and stone consolidation of monuments and memorials. This way, using PROTECTOSIL® very efficiently prevents serious damage, and algae, mold, and other contaminants don't stand a chance. With PROTECTOSIL® and the power of silanes, construction quality, and aesthetic beauty are preserved for decades.
