A new topcoat for injection molded liquid silicone elastomers is said to lower the coefficient of friction (COF) of molded medical parts such as catheters, prosthetics, and valves for reduced sticking and greater wear resistance.
A new topcoat for injection molded liquid silicone elastomers is said to lower the coefficient of friction (COF) of molded medical parts such as catheters, prosthetics, and valves for reduced sticking and greater wear resistance. Developed by GE Advanced Materials, Silicones, Waterford, N.Y., its LSR Top Coat lowers the COF by 56%, which also helps prevent adhesion of dust particles. The topcoat can be applied easily by dipping, spraying, and brushing prior to curing in an air-circulating oven for 10 to 30 min at 100 to 180 C.
