Moisture cure polyurethanes have been widely used in the adhesive and coating industries. Thermal, mechanical, and surface properties of hyperbranched polyurethane-urea (HBPU) moisture cured coatings have been studied in relationship to chemical structure. [3]

Polyurethane synthesis, wherein the urethane groups −NH−(C=O)−O− link the molecular units A kitchen sponge made of polyurethane foam . Polyurethane (/ ˌ p ɒ l i ˈ jʊər ə ˌ θ eɪ n,-j ʊəˈr ɛ θ eɪ n /; [1] often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links.
Quilting templates/patterns come in many varieties and are generally considered the basis of the structure of the quilt, like a blueprint for a house. Bias binding or bias tape can be made from strips of quilt fabric or purchased as quilt binding. It is used in the last stage of making a quilt, and is a method of covering the edges of the quilt.
The glue gun melts the solid adhesive, then allows the liquid to pass through its barrel onto the material, where it solidifies. Thermoplastic glue may have been invented around 1940 by Procter & Gamble as a solution to the problem that water-based adhesives, commonly used in packaging at that time, failed in humid climates, causing packages to ...
Georgia Bonesteel is a quilting judge, author and host of the show. She has been the president of the International Quilt Association, which is involved in the history and art of quilting worldwide. [6] Bonesteel is credited with having invented lap quilting while teaching a class at Blue Ridge Community College in North Carolina. [2]
There are three major requirements of creating a desirable surface for adhesive bonding of plastics: the weak boundary layer of the given material must be removed or chemically modified to create a strong boundary layer; the surface energy of the adherend should be higher than the surface energy of the adhesive for good wetting; and the surface profile can be improved to provide mechanical ...
In the art of bookbinding, the longstitch technique is used for binding the sections (signatures) of a book without using glue. In Non-adhesive Binding: Books without Paste of Glue (1999) Keith A. Smith describes that binding a book with a "longstitch through a slotted cover" involves directly sewing each section through the cover, which has ...
