Embodiment

[0054] The examples provided herein were prepared using the following textile coating formulations. All starting materials used here were obtained from ICAP-Sira.

[0055] Coating polymer 100g aq.

[0056] Defoamer, Icawet N 1 drop

[0057] Ammonia 1% 1g

[0058] Thickener Acrilem 36630 3g, up to 15000mPas

[0059] The coating polymer can be polyurethane, acrylic, styrene-acrylic or silicone polymers. In the examples where silicone additives were used, 5% wetting agent was added.

[0060] A typical laboratory procedure for producing samples is described below. The polymer dispersion formulation listed above was applied to a sheet of polyester fabric held in a clamping device approximately A4 in size. Hand coating is done using an air knife process followed by drying by any standard process known in the art. Use roll-on-roll coating head, adopt 40g / m 2 A solvent based acrylic adhesive, such as Durotak 1104 available from National Starch & Chemical, applies the adhesive ...

Abstract

This invention relates to adhesive tapes comprising a polyester support, a polymer coating, and an adhesive layer. The polymer coating may be on the side opposite the adhesive layer or between the support and the adhesive layer. The adhesive tape of the present invention is particularly suited for wire harnessing in the automotive industry.

Description

[0001] This invention relates to abrasion resistant adhesive tapes. The tape is especially useful as a wire harnessing tape used in the automotive industry. Background of the invention [0002] Pressure sensitive adhesive (PSA) tapes are widely used in the automotive industry to prepare wire harness assemblies. Applying different adhesives to special liners and carriers such as films, foams and textiles provides products for every requirement. Although PSA tapes represent only a portion of the overall component cost, they are critical to making cost effective automotive wiring harness assemblies. In 2003, the motor vehicle industry worldwide used more than 150 million m 2 Wire harness tape. [0003] The average wiring harness system for a vehicle consists of approximately 1000 meters of wire and runs from the engine compartment through the passenger area to the truck. These different environments require tapes with various properties. For example, tapes used in engine com...
