Abstract
Official abstract text for this publication.
A polyurethane foam article comprises a first lift, a second lift, and a pass-line therebetween. The polyurethane foam article comprises the reaction product of an isocyanate-reactive resin composition, an isocyanate, and an indicator dye in the presence of a blowing agent. The indicator dye imparts a color in the first and second lifts and at the pass-line at a first temperature below a decomposition temperature of the indicator dye. The indicator dye chemically decomposes to impart a change in color in the first and second lifts and at the pass-line at a second temperature which is at or above the decomposition temperature of the indicator dye.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming a polyurethane foam article on a substrate, the polyurethane foam article comprising a first lift, a second lift, and a pass-line therebetween, and comprising the reaction product of an isocyanate-reactive resin composition, an isocyanate, and an indicator dye, in the presence of a blowing agent, said method comprising the steps of: A. providing the isocyanate-reactive resin composition; B. providing the isocyanate; C. providing the i…
