Bohle BriteGuard® Surface Sealer is granted TÜV certification

The new surface protection product, BriteGuard® Surface Sealer, ( developed and produced by Bohle, has been subject to thorough testing by the German Technical Inspection Agency (TÜV) Rheinland.

By granting the TÜV certification, the independent institution has confirmed the outstanding properties of the product: Surfaces protected by BriteGuard® Surface Sealer are dirt-repellent and easy to clean – for a long period of time. During complex tests, a 10-year service life was simulated, which hardly affected the efficiency of the BriteGuard® surface protection. Those long-term tests have proven that BriteGuard® shows durable resistance to wear, standard household cleaners, temperature and UV radiation both for interior and exterior applications. Glass protected with BriteGuard® Surface Sealer stays dirt-repellent and easy to clean for many years: blank


BriteGuard® Surface Sealer is the core product of the BriteGuard® modular system. Smooth glass both in interior and exterior settings is quickly and reliably protected against corrosion and dirt adhesion. Due to the beading effect of water when in contact with the coating, shower cubicles, balustrades, facades, conservatories or canopies become dirt-repellent and can be cleaned much easier than uncoated surfaces. Moreover, glass surfaces are durably protected against corrosion.


BriteGuard® Surface Sealer protects glass surfaces very efficiently, but its application is as easy as can be. After application, the product forms chemical compounds with the glass surface. The product can either be applied manually on site in 3 easy steps using a spray gun or cotton pads, or it can be applied mechanically immediately after manufacturing the glass.


"The TÜV certification is an important step to underpin the trust which many customers around the world have already placed in the BriteGuard® coating system", explains Volker Brock, product manager for surface protection products.

After a development and testing period of many years, Bohle launched the system, which also includes BriteGuard® Surface Sealer X for protecting rough surfaces, such as sandblasted or satin-finished glass, on an international scale in the beginning of 2011.

BriteGuard: A new generation of surface protection

With BriteGuard® (, Bohle is launching a revolutionary new protection product for glass and glazed ceramic surfaces, which is both extremely wear resistant and durable. Further, the application process is simple and can be done either manually or mechanically.

There are a multitude of surface protection products for glass and glazed ceramics available in the market offering various degrees of protection for glass. In reality, however, not all live up to the durable protective effect they promise. Moreover, application is often complicated and care problematical. With its new BriteGuard® surface protection system, Germany-based Bohle Group, is taking the first step in offering a new generation of surface coating systems, setting completely new standards as far as application and durability are concerned.

The innovative surface protection system for both smooth and textured glass surfaces is extraordinarily wear resistant and durable. Another advantage is that the BriteGuard® system requires a minimal number of products and can easily be applied, either manually or mechanically. Once again, Bohle offers a highly attractive business opportunity for glass processing companies. In addition to high quality glass products they can supply their customers with a high perceived value surface protection system developed for professional use without expensive application equipment and complex and time-consuming product training.


For Indoor and Outdoor Applications

BriteGuard® is significantly more wear resistant than other surface protection products currently available in the market. By reacting chemically with the surface, the coating forms a high strength functional layer that effectively protects the glass against soil adhesion and glass corrosion. Compared to untreated glass, surfaces protected with BriteGuard® simply stay clean much longer and are much easier to clean. This Bohle innovation demonstrably counters the poor reputation of the durability of surface coating products within the glass trade. BriteGuard® can be used for indoor and outdoor applications and is thus equally suitable for protecting partition walls or glass showers as well as facades.


Clearly structured modular system

When developing BriteGuard®, the main focus was on the easy handling of the coating system both for the glass processing businesses and for the end user. Having this in mind, a clearly structured, simplified, modular system was developed consisting of only few components for pre-treatment, coating and care. This makes selecting the appropriate materials for the respective application intuitively simple.

BriteGuard® Surface Sealer is suitable for protecting smooth glass surfaces and requires a pre-cleaner and final cleaner. For protecting rough surfaces, only BriteGuard® Surface Sealer X is required. Also when it comes to the care for coated glasses, Bohle strives to maintain simple processes as far as possible. Instead of a multi-component product range, the BriteGuard® system consists of a care kit for smooth and rough glass surfaces and a product for regular cleaning. Moreover, the complete coating product package includes the whole array of accessories - ranging from cleaning cloths to protective glasses.


Convincing Efficiency

After BriteGuard® Surface Sealer has been applied; it reacts with the surface and forms a high strength functional layer that replicates the structure of the glass or glazed ceramic surface. The surface tension of this functional layer is extremely low, ensuring that organic soiling (e.g. from soap residues, bird droppings or traffic pollution) and inorganic soiling (e.g. limescale or salty air) hardly stick to the glass surface and can be removed very easily. The low surface tension can be seen in the familiar beading effect that occurs when in contact with water. In the case of rough surfaces such as sandblasted and frosted glass, undesirable soiling like finger marks can be effectively avoided by treating the glass with BriteGuard® Surface Sealer X.

Comprehensive tests have proven the long-term stability of the BriteGuard® system: The coating products exhibit an extraordinary wear resistance. Even after 170,000 wipe cycles with a conventional squeegee, the contact angle with water remains nearly unchanged. Even storing the coated glass continuously for 500 hours in different chemicals and widely available cleaning agents had virtually no effect on the coating. The BriteGuard® functional layer even withstands temperatures up to 200°C, humidity and UV radiation without significant loss of functionality.


Easy Application

In keeping with simplicity of the system, no time-consuming training has to be carried out before applying BriteGuard® for the first time. The surface protection product can be applied manually with a cotton pad, with a simple spray bottle or mechanically with an applicator.

BriteGuard® protection is achieved in only 3 steps. Before applying the coating, smooth surfaces are cleaned by hand or in a glass washing machine using BriteGuard® Surface Activator. It reliably removes organic as well as inorganic contamination from the glass surface. Rough surfaces simply have to be thoroughly cleaned to remove dust and grease.


The protective coating is applied in the second step. BriteGuard® Surface Sealer is suitable for smooth surfaces and BriteGuard® Surface Sealer X is designed for rough or textured surfaces. The application can selectively be done either manually or mechanically. Simply ensure the protection product is spread evenly over the entire surface.

After the coating has cured, excess material is removed in the third step. BriteGuard® Surface Finisher is then applied to smooth surfaces. The application can again be done either manually using a squeegee or chamois or mechanically in a glass washing machine. No final cleaning is required for rough surfaces. Simply polish them with a microfibre cloth.


High resistance

The BriteGuard® protection is extremely wear-resistant and durable. Once professionally applied, under normal circumstances the protective function can typically remain for up to 15 years. The prerequisite for maintaining the protection is cleaning the glass only with typically available agents instead of aggressive or abrasive products or compounds. Nevertheless, even the BriteGuard® surface protection cannot do without refreshment. It depends on the degree of wear of the surface after which time a refresher is needed.
Bohle recommends refreshing the coating once the beading effect is noticeably reduced on the clean glass surface.
