Protection / Protectants:
There are two main degrading agents that attack tires, plastic and vinyl—ultraviolet (UV) light and ozone. Both of these attack the long hydrocarbon chains of the rubber, trim, and vinyl skin by breaking these bonds, shortening the molecules with a resulting loss of elasticity and other problems.
Tire manufacturers add two primary sacrificial protectants to the rubber. To protect against UV, manufacturers add carbon black. This is why tires and trim are most always black. The carbon black will turn white or gray as it absorbs the UV and protects the rubber. This is the basis of rubber parts turning gray as they age. To protect against ozone, tire manufacturers add a wax-based sacrificial protectant. The ozone attacks the wax and depletes it. As the tire rolls, additional wax is forced to the surface of the tire. This is referred to as blooming. This blooming refreshes the surface wax protectant. A tire that has not been flexed will have the wax depleted by the ozone and thus begin to degrade and suffer dry-rot. Raw silicone oil, which is the main ingredient in most all of the advertised protectants, actually dissolves the wax and is the cause of premature tire sidewall cracking and failure. Some tire manufactures may not honor their warranty on damages if use of silicone products is detected.
Vinyl surfaces have a protective skin and just as plastic surfaces it is depleted from off-gassing. Silicone oil may also dissolve the essential oils in the skin, hastening the premature formation of cracks in the vinyl. Silicone oil also has a electrostatic attraction which attract dirt and dust particles. A quality protectant should contain a strong UV protectant to bolster the efforts of the carbon black and not contain any silicone oil. Many of the nationally advertised rubber and vinyl products also contain formaldehyde and harsh surfactant elements.
Renew Protect supplies co-polymer essential feeding elements that restore the original composition of the surface and create a dry-seal ozone and UV block. This technology also serves to retard the “blooming” and “off-gassing” process and greatly enhances the retention of protective elements within the surface. Renew Protect Blak also contains carbon black and is ideal for the restoration of faded black surfaces and of their protective properties. Renew Protect is silicone-free.
