Coil zipper whose tape is attached with a layer of TPU film that serves a water-repellent purpose is referred to as rubberizing waterproof coil zipper.
Please follow the instructions below when you are using rubberizing waterproof coil zippers to achieve better functioning and prolong their service life.
Water Repellency Effect
Although this type of zipper is not fully waterproof as water may still seep through the sealed rubberizing film, through the gap among the teeth elements or through the gap in the zipper tape, it does save additional water protection treatment to these zippers when they are attached to the outdoor gears.
Frequent folding and bending of the zipper, or frequent movement of the slider will cause the film to blanch. Please rest assured this won’t affect its water-repellency performance.
Rubberizing waterproof zippers come available in 3 categories, namely, matte surface, shiny surface and half-matte surface. A wide array of colors are available for choice.
Please note these zippers will look darker when compared with the regular zippers due to the special properties of polyurethane. Furthermore, the side onto which the film is attached will be darker than the other side. Please keep this in mind before purchase or bulk manufacturing.
Rubberizing waterproof coil zippers are suitable for such applications that serve decorative purposes like plackets, pockets, etc. They are primarily recommended for the apparel industry, together with the soft bag products.
Unless otherwise specified, please double check with our sales persons if you would like to attach them to any other items.
- These zippers should be used in the environment whose temperature falls below 100℃. Please double check with us if the temperature goes above 100℃.
- As far as the cold resistance is concerned, the layer won’t peel off even if the temperature falls as low as minus 30℃.
If the fabric to be sewn onto contains any Dioctyl Phthalate (DOP), use a sheet of paper to separate the fabric from the zipper teeth to prevent the color film on the teeth surface from reacting with the DOP that can result in migration.
Please opt for spray painted sliders for this type of zippers.
Improper washing can damage the rubberizing film and affect its water-repellent performance. Completely zip up the zipper when washing.
- Avert such dry cleaning solvents that contain chlorine as they may make it difficult to open and close the zipper and cause the zipper to fade in color. Additionally, they can result in dye transfer and cause the film to blanch and come off.
- Opt for petroleum-based dry cleaning solvents.
- Avoid drying the garments in the dryer. This may cause the rubberizing film to break and even cause it to fall off completely. Place them in a well-ventilated place and allow them to dry naturally.
- Take care the zipper does not come into direct contact with the iron to protect the rubberizing film from breaking and coming off.
- Make sure the ironing temperature falls below 150℃. Otherwise, the film will melt or bubble.
- Avoid direct or prolonged contact with vinyl chloride, PVC and polyurethane to prevent dye transfer.
- Avert direct exposure to the sunlight to prevent the product color from fading or getting yellow.
- Avoid direct contact with the chemicals or organic solvents, as they can cause the rubberizing film to bubble and even cause it to fall off completely.
