How do YKK zippers self lubricate and zip more smoothly with more use?

1.16K views

I’ve been researching this all morning and keep running into articles that explain why YKK is a great company and what is unique about their zippers, but no article that explains the technical design of the product.

Would love an explanation that goes beyond the very simple “YKK zippers actually lubricate themselves as you zip and unzip them.”

Thank you!

After more than twenty years and I can finally understand this OutKast verse: “[Let me be bambino on your snipples YKK on yo’ zipper, lick you like a – lizard when I’m slizzard or sober; six million ways to fold ya](https://youtu.be/-JfEJq56IwI)”. Thanks OP!

According to the available documentation, their self-lubricating zippers are made of a polymer (essentially a plastic) mixed with what they refer to as a “slip additive”, which appears to be a waterproof lubricating agent. The polymer is porous and so allows the lubricant to come out upon the zipper being used.

FYI- YKK stole most of their designs from the US zipper maker TALON, after their patents expired.

While YKK zippers may be the good standard now, they are in fact cheaper knock-offs of the original product
