CCM expands portfolio: New high-performance coating 646 now available

With 646 Permanent Protect, CCM® introduces another product in its range of Liquid Glass high-performance coatings. This innovative solution bridges the gap between ultra-thin 100 nm layers and industrial coatings starting at 1 µm – with a typical layer thickness of approx. 500 nm.

Key benefits at a glance:

• Thinner. Stronger. More versatile. Ideal for applications where other CCM® industrial coatings (640, 643, 7641) are too thick, and standard Liquid Glass coatings (e.g., 7656) are not robust enough.
• Ceramic high-performance coating, resistant to heat up to 600 °C, chemicals, UV radiation, and abrasion.
• Perfect for smooth surfaces such as metal, glass, plastic, or painted materials – whether in automotive, marine environments, or as an anti-graffiti solution.
