CLOSURE PATCH

Fix tape for Heat shrinkable sleeve 

Description

Closure patch is applied on the overlap of the heat-shrinkable sleeve for fixing and

sealing.  

Construction: Two-layer system                                        

Adhesive: High temperature, high lap shear strength.

Backing: Radiation cross-linked, high density polyethylene backing with glass fiber.

Application guide

1. Use hand roller to flat the surface of overlap sleeve. Make sure no bubble inside. Position the closure patch onto the edge of overlap of sleeve end. Make sure evenly on both side.

2. Lift one side of closure patch, heat the surface of a closure patch adhesive and the surface of overlap sleeve, ensuring the adhesive sufficiently melt. Press down by gloved hand and ensure the surface of a closure patch is flat. Then heat the other side of a closure by same way. 

3. After the sleeve shrinking, the air bubbles under the closure patch should be quickly removed. Press the whole patch with the roller to ensure flat and pasted completely.

Recommended:

Paste attached two adhesive strips filler on both ends of closure patch, heat adhesive filler melting entirely. Flat melted filler surface by Spatula. Brash epoxy primer on two sides of closure patch, ensure completely seal the edge.
