“SPF 40 SUNSCREEN” For Your Stuff – Lubricates and Protects MaxiGrip Industrial Zippers

MaxiGrip recommends the use of 303 Aerospace Protectant for the care and maintenance of your chemical resistant and waterproof zipper closures. 303 Aerospace Protectant is recommended to lubricate zipper tracks for easier closure. It is suggested to apply lubricant after any welding as not to interfere with the welding process.

Developed for aerospace and aviation applications, 303 is the world's most effective UV screening product and is ideal for plastic zipper maintenance. Unlike other "protectant" products, 303 does not contain silicone oils, waxes, glycerin or petroleum distillates. 303 leaves a like-new, non-oily, anti-static finish that does not attract dust. Treated closure surfaces stay cleaner longer, reducing maintenance.
