THE WIDESPREAD CHALLANGE
The aging behavior of TPU-coated, waterproof zippers has been a significant focus of TIZIP’s product development for decades.
It has been mostly analyzed that TPU coating material failure, characterized by swelling, cracks, or delamination, is caused by aging (moisture, temperature, microorganisms, etc.), known as hydrolytic degradation processes. Despite various handling precautions contributing significantly to minimizing hydrolytic degradation, TIZIP has now developed a optimized TPU coating material that eliminates the typical aging behavior of TPU-coated zippers in the long term.
THE TIZIP® SOLUTION
Especially in the watersports sector, where waterproof zippers are exposed to constant moisture, the new hydrolysis protection represents a significant advantage compared to short-lived products with conventional material.
Discover the great opportunities and outstanding advantages of TIZIP’s hydrolysis protected zipper, how it fits and significantly extends the lifespan of your next waterproof or airtight project.
COMPATIBILITY
Please note that PVC is not chemically compatible for direct welding with the hydrolysis-protected zipper. Therefore, PVC must be glued to the hydrolysis-protected zipper material or, alternatively, used with an intermediate TPU layer.

STANDARD ZIPPERS
On May-01 2024, the new “hydrolysis protection feature” has been launched to all MasterSeal #10 versions that are included in the standard zipper program.
Brands, factories and consumers are able to visually identify the new “hydrolysis protection” marked on the zipper tape:
1) wording “HYDRO” on the end stop (backside).
2) embossed lines along the zipper tape (back & frontside).

NON STANDARD ZIPPERS
For MasterSeal #10 zippers not included in the standard program and for SuperSeal zippers, the “hydrolysis protection” can be selected as an option.
Shortly, TIZIP will also launch the “hydrolysis protection feature” as an option for the MasterSeal #6.
