Technical Information

IMPORTANT NOTE

Sika® Spacer Tape HD will main­tain its shape and size under most conditions, but is not intended to be a structural component.

Once the spacer tape is applied, it must not be removed and reused. It is thus essential to position tape carefully. Make sure the product is in contact with both surfaces. If unit is not correctly aligned, remove used spacer tape, discard and repeat application with new tape.

Sika® Spacer Tape HD is compati­ble with Sikasil® SG, WT, WS and IG sealants and adhesives. All other sealants must be tested by the manufacturer for compatibility and need to be approved by Sika before usage. 

Sika® Spacer Tape HD may only be used in structural glazing or window bonding applications by experienced professionals and after a detailed examination and written approval of the corre­sponding project details by the Technical Department of Sika Industry.

Application of spacer tapes exceeding 20 mm width may cause encapsulation of air bubbles which may be visible behind clear glass types.

 

Application

Application Information

Surface preparation

Substrates must be clean, dry, free from grease, dust and loose particles.

Application

Align and apply the tape to one contact surface and make sure that the intended joint dimensions are kept. Press the tape onto the sub­strate. Remove the protective liner and immediately put the second substrate (previously cleaned, see above) onto the tape.
