Abstract
Official abstract text for this publication.
This invention is directed to stretchable polymer thick film compositions useful for wearable garments. More specifically, the polymer thick film may be used in applications where significant stretching is required, particularly on substrates that can be highly elongated. A particular type of substrate is a thermoplastic polyurethane substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A polymer thick film encapsulant paste composition comprising: (a) fumed silica; and (b) an organic medium comprising 5-50 wt % thermoplastic polyurethane resin dissolved in an organic solvent, said thermoplastic polyurethane resin having a per cent elongation of at least 200% and a tensile stress necessary to achieve 100% elongation of less than 1000 psi, wherein the weight percent is based on the total weight of said organic medium. 2. The polymer thick film encapsulant paste composition of claim 1 , said polymer thick film encapsulant paste composition comprising 0.1 to 3 wt % fumed silica and 97 to 99.9 wt % organic medium, wherein the wt % are based on the total weight of said composition and wherein said thermoplastic polyurethane resin is selected from the group consisting of a polyester-based polymer, a urethane homopolymer and a predominantly linear hydroxyl polyurethane.
