Care Recommendations

- When attaching the zip, we recommend a minimum gap of 2 mm between the spiral edge and edge of the leather, to ensure the slider runs correctly. This is as per the SATRA recommendation.

- Excessive glue should be removed. Caution should be taken to ensure the glue pots and dispensers are positioned away from the teeth and slider.

- During the soiling out process, the side pushes can be an issue if they press against the slider.

- Attention must be taken with the thickness, width and positioning of the zip guards.

- When the zip goes through the curing tunnel, the slider should be pulled to the top of the boots, and the boots should be laid down with the slider facing upwards.

Sewing recommendation for Opti S zips – Whilst sewing, the presser foot can accidently go over the spiral and stitch line and as a consequence this can affect the slider running.

Sewing recommendations for Opti M zips - When applying the zip to the bottom edge, the sewing line needs to be just below the bottom stop. Care must be taken to keep a straight sewing line, because there is a risk of needle breakage if it comes into contact with the teeth.

Since conditions and applications vary considerably in the use of the thread, Coats and its distributors can make no guarantee of results. These recommendations are given in good faith but without warranty or liability on the company or its employees. The thread user should assure herself or himself by preliminarily testing that the thread is suitable for the end use intended.
