  • Patent number: 9821512
    Abstract: A two-component reactive dispensing system that is pliable is comprised of an outer sausage tubular member having therein an inner sausage tubular member in which the inner tubular member is bonded to the inner surface of the outer sausage tubular member longitudinally along a portion of the outer surface of the inner tubular sausage member. The compartments formed by the inner and outer tubular sausage members are filled with materials that are reactive with each other and the ends are sealed by gathering the ends and sealed using, for example wire wrap around clips.

  • Patent number: 9822290
    Abstract: A composition comprising: a one part adhesive composition comprising a) one or more isocyanate components; b) one or more catalysts for the reaction of isocyanate groups with active hydrogen containing groups; c) one or more fillers which do not enhance the formation of voids during curing; d) one or more fillers having basic character; and a cure accelerator comprising: e) one or more liquid carriers; f) water; and g) one or more paste forming agents. The one part adhesive composition may be used alone where ambient temperature and humidities afford reasonably rapid cure rates. The cure accelerator may be used when temperatures and/or humidities are sufficiently low such that the cure rate of the adhesive alone is not acceptable for a particular use.
