Can BA940 be used upside down?
Yes. The 300ml format is equipped with a 360° spray system, allowing effective application even when the can is held upside down. This makes it ideal for hard-to-reach or awkward areas.
Is BA940 silicone-free?
Yes. BA940 is silicone free, providing cleaner maintenance without heavy or sticky residue build-up. This helps reduce dust and dirt attraction and keeps surfaces suitable for future painting, sealing, or bonding work.
Is BA940 suitable for indoor and outdoor use?
Yes. BA940 can be used both indoors and outdoors. For indoor use, always apply in well-ventilated areas. For outdoor applications, periodic reapplication may be required, especially after heavy rain or prolonged exposure to the elements.
Can BA940 be used on electrical components?
BA940 may be used to displace moisture and protect external electrical connections only, such as battery terminals or exposed connectors, provided the power is disconnected.
It is not suitable for electronic components, computer boards, electrical outlets, or live electrical systems. For these applications, a dedicated electronics contact cleaner should be used.
Can BA940 be used on plastics and rubber?
Yes. BA940 can be used around plastics and rubber for general maintenance applications. Its silicone-free formulation makes it safer to use around mixed materials compared to heavier silicone or oil-based sprays.
Does BA940 need to be reapplied after rain?
Yes. When used outdoors, rain and weather exposure can gradually reduce the protective layer. Reapplication is recommended to maintain lubrication, moisture displacement, and corrosion protection on exposed components.
Will BA940 attract dust or leave residue?
BA940 is formulated to provide effective lubrication and protection without leaving excessive or sticky residue. When applied sparingly, it helps reduce dust build-up compared to heavier oil or silicone-based sprays, making it suitable for cleaner indoor applications.
