  • Patent number: 9011980
    Abstract: A dampening device and method of making are provided, in which the method includes providing a first layer of a sponge rubber. An isocyanate-base prepolymer and a polyol base curing agent are combined to form a curable liquid urethane polymer. The curable liquid urethane polymer is shredded and during shredding air in the form of micro-bubbles is entrained in the curable liquid urethane polymer. The curable liquid urethane polymer is applied to form a second layer overlying the first layer and is then cured to form a tacky polyurethane cast elastomer. Micro-bubbles remain present in the tacky polyurethane cast elastomer and curing bonds the first and second layer forming a dampening device. The dampening device includes a first layer of neoprene and a second layer of a micro-bubble infused tacky polyurethane cast elastomer bonded to the first layer.

In the method, the heated surface temperature and the condensing surface temperature are such that the positioning step causes the nonresident volatile component to be selectively removed from the portion of the coated substrate.
