PROBLEM TO BE SOLVED: To provide an energy-activated room-temperature pumpable polymer composition, a devices for activating and processing the composition into a solid cellular or non-cellular polymeric material that can be used as an adhesive, a sealant, a coating or a gasket material, and a method of making and using the composition and the device.SOLUTION: A composition includes solid particles which include one or more polymers which are emulsified, dispersed or suspended in a liquid carrier together with at least one processing aid such as a reactive blowing agent, a low molecular weight surfactant, a high molecular weight surfactant, one or more compounds found in latex paint, starch, a cellulosic derived product and a combination of two or more thereof. The processing aid provides various benefits including, for example, reduced density, improved process hygiene, improved foam stability, the shortening of a bonding time and/or the lowering of a processing temperature. |
