Aqueous adhesives. |
摘要 |
<p>A sheet material, generally a wallcovering, is adhered to a substrate, generally a wall or ceiling, by an adhesive which is formed by contacting with water a composition that is free of liquid and comprises substantially dry, unswollen polymer particles comprising water-soluble and/or water-swellable polymer particles having particle sizes greater than 20 microns. The polymer may be wholly synthetic or may be a homogeneous blend with a natural polymer. The particles have a surface coating which promotes the dispersibility of the particles in water. The adhesive may be a brush-on adhesive or may be coated on to the sheet material as a pre-paste. Prepastes of synthetic polymer particles without the surface coating are also described.</p> |
