WD-40 is a popular multi-use lubricant that has been around for over 65 years. It is known for its ability to lubricate, protect, clean, and displace moisture. WD-40 Silicone, on the other hand, is a variant of the original formula that is specifically designed for use on surfaces that require a high level of water resistance. In this answer, we will explore the differences between the two products in detail.
Composition:
The primary difference between WD-40 and WD-40 Silicone is their composition. The original formula of WD-40 is made up of a blend of petroleum-based oils and solvents, while WD-40 Silicone is made up of a silicone-based formula.
WD-40 is composed of 50% mineral oil, 15% stabilizer, and 35% solvent. The solvent is a mixture of heptane, hexane, and carbon dioxide. The mineral oil helps to lubricate and protect surfaces, while the solvent helps to dissolve and remove dirt and grime. The stabilizer helps to keep the formula consistent and stable over time.
WD-40 Silicone, on the other hand, is made up of 50% silicone oil, 45% solvent, and 5% propellant. The silicone oil provides excellent water resistance and lubrication, while the solvent helps to dissolve and remove dirt and grime. The propellant is used to spray the formula onto surfaces.
Uses:
WD-40 is a versatile product that can be used for a wide variety of applications. It is commonly used as a lubricant for squeaky doors and hinges, as well as for loosening rusted or stuck nuts and bolts. It can also be used to clean and protect metal surfaces from rust and corrosion.
WD-40 Silicone, on the other hand, is specifically designed for use on surfaces that require a high level of water resistance. It is commonly used on rubber seals, gaskets, and other surfaces that come into contact with water. It can also be used to lubricate and protect plastic and metal surfaces.
Water Resistance:
One of the primary benefits of WD-40 Silicone is its excellent water resistance. The silicone-based formula creates a barrier that repels water and prevents it from penetrating surfaces. This makes it an ideal choice for use on surfaces that are exposed to water or moisture on a regular basis.
While WD-40 is also water-resistant to a certain extent, it is not designed specifically for use in wet environments. It can provide some protection against moisture and can help to displace water from surfaces, but it is not as effective as WD-40 Silicone in this regard.
Compatibility:
Another important factor to consider when choosing between WD-40 and WD-40 Silicone is their compatibility with different materials. WD-40 is generally safe to use on metal, plastic, and rubber surfaces. However, it is not recommended for use on certain types of rubber, such as neoprene and silicone.
WD-40 Silicone, on the other hand, is specifically designed for use on rubber and plastic surfaces. It is safe to use on most types of rubber, including neoprene and silicone. However, it may not be as effective on metal surfaces as the original formula of WD-40.
Price:
The price of WD-40 and WD-40 Silicone can vary depending on the size of the container and the retailer. Generally, WD-40 Silicone is slightly more expensive than the original formula of WD-40. However, the cost difference is not significant and is often outweighed by the benefits of the silicone-based formula for water-resistant applications.
Conclusion:
In conclusion, the primary difference between WD-40 and WD-40 Silicone is their composition and intended use. The original formula of WD-40 is a versatile multi-use lubricant that can be used for a wide variety of applications, while WD-40 Silicone is specifically designed for use on surfaces that require a high level of water resistance. WD-40 Silicone provides excellent protection against water and is safe to use on most types of rubber and plastic surfaces. However, it may not be as effective on metal surfaces as the original formula of WD-40. Ultimately, the choice between these two products will depend on the specific application and the level of water resistance required.
