Guardian BPC
Innovative protection for heat-treatable coated glass
Guardian BPC is a temporary protective coating applied to the coated surface of the glass. It protects the coated glass surface during transport, storage and handling, and is intended to burn off in the tempering furnace, eliminating the need for temporary protective film on HT coatings.
Why Guardian BPC coating?
Sputter coatings are composed of metal oxide layers that give glass its advanced energy performance. However, some of these coatings can be vulnerable to scratches, marks, and other quality issues during transport and processing, such as cutting, edge deletion, and tempering. For glass processors, protecting these coatings helps maintain product quality and improve yield throughout the transformation process. Guardian BPC coating delivers a range of practical advantages designed to help glass processors protect coated glass effectively during glass processing.
What are the benefits of Guardian BPC coating?
Reduced tempering cycle time
Guardian BPC coating can help shorten tempering times by up to ~12%, depending on the thickness of the glass and the type of furnace, supporting improved operational and energy efficiency in your processing lines. Our technical experts are available to assist you on site to help optimize the time savings through a dedicated setup and adjustment process.
Streamlined edge deletion and preparation
Edge deletion of coatings protected by Guardian BPC coating is performed like standard coated glass and takes the same time as processing unprotected glass. There is no need for special equipment or additional steps due to the protective layer. During the cutting and edge deletion process, Guardian BPC generates minimal to no dust and odor.
Improved yield and efficiency
From simplifying handling to saving time during preparation and tempering, this innovative solution supports a smooth process from delivery to heat-treatment. By reducing the risk of scratches and quality defects, Guardian BPC coating also helps improve overall yield.
