The two products in this section are applied directly to metal surfaces, components and moving parts to protect against rust and corrosion. BIO WDF is a biodegradable multipurpose fluid that penetrates, lubricates and displaces moisture, while Soft Coat CPF forms a soft, waxy protective film intended for longer term protection. Both products are suitable for pins, bushes, screws, valves, chains, bearings, couplings, levers, locks, hinges, cables, pulleys and winches.
CPVI differs from the other products in the range through its function as a vapour phase corrosion inhibitor. Rather than only protecting the surfaces it directly contacts, the product fills the entire closed space with protective vapours. This makes it particularly suitable for engines, gearboxes, fuel tanks and other closed systems that will be placed into storage for an extended period.
What is the difference between BIO WDF and Soft Coat CPF?
BIO WDF is a multipurpose fluid intended for shorter term protection and is often used to penetrate seized parts and displace moisture. Soft Coat CPF forms a more durable, waxy protective film and is better suited for longer term storage of components and spare parts.
Can I use CPVI on open surfaces?
No, CPVI is specifically designed for closed systems such as engines, gearboxes and fuel tanks. The product works by filling the closed space with protective vapours, which requires the system to be sufficiently sealed to function effectively.
How long does CPVI protect a closed system?
The protection period can be up to one year, but the exact duration depends on how well sealed the system is and how much temperature induced breathing occurs in the system.
Is BIO WDF biodegradable?
Yes, BIO WDF is made from bio-based, sustainable ingredients and is biodegradable, reducing environmental impact in the event of a spill compared to conventional products.
Which product is best suited for outdoor storage of spare parts?
Soft Coat CPF is particularly suitable for outdoor storage thanks to its durable, waxy protective film that provides long-term protection and resists cracking, peeling and chipping.
