- Fast drying – useful in busy workshops where preparation time needs to be kept to a minimum.
- Corrosion protection – Metaflux describes 70-49 as providing dual corrosion protection through its high copper-metal content and synthetic resin protective layer.
- Ideal for automotive bodywork – the manufacturer's documentation specifically identifies vehicle bodywork, metal containers, housings and coverings as application areas.
- Economical to use – the product is supplied as a 400ml aerosol and is designed for economical application.
Why use it for spot welding ?
For spot welding applications, the welding area needs to maintain suitable electrical contact while also being protected from corrosion. Metaflux 70-49 combines a metallic copper coating with a protective resin layer, making it useful for preparing and protecting areas around spot welds. The manufacturer's technical information specifically lists spot welding, tack welding and plug welding among its applications.
