Vapour Flux & Paste

Brazing vapour flux & paste, is specially formulated to protect the joint area during the brazing process by preventing oxidation and enhancing the flow and wettability of silver brazing filler metals. It ensures stable capillary action and reliable filling performance, resulting in clean and uniform joints.

They widely used for brazing copper, copper alloys, stainless steel, carbon steel, and other engineering metals, especially in refrigeration and air-conditioning applications. They contribute to strong mechanical performance, good corrosion resistance, and consistent joint quality.
