  • Publication number: 20230104319
    Abstract: The present disclosure is directed to a formulations of cements and methods for bonding dissimilar materials. The formulations and methods can bond a Non-polyvinyl chloride (PVC) containing first polyolefin that is amorphous or has low crystallinity to a second material that is a rigid material or a hard PVC. The methods and formulations can work by co-dissolution at an interface, or activation of a one of the materials prior to bonding.

  • Patent number: 7332227
    Abstract: A non-volatile lubricious coating composition is provided for use with medical devices, such as hypodermic needles, catheters, and the like. The coating composition includes a first siloxane polymer having a very low viscosity less than about 50 centistokes, a second siloxane polymer having a high viscosity greater than about 1,000 centistokes, a reactive silicone polymer which is capable of crosslinking upon exposure to radiation, such as a UV curable silicone acrylate, and a photoinitiator to accelerate cross-linking of the reactive silicone polymer. The coating composition may further include an aminofunctional siloxane polymer to promote adhesion to metal surfaces when used with needles. The coating composition provides flowability without the need for any volatile organic solvent, and is capable of curing to provide adhesion and lubricity.
