Patent

CA 2493813

The invention relates to a lubricant for medical devices. The inventive lubricant uses silicone epoxy and vinyl ether that both rapidly cure when exposed to ultraviolet light or an intense electron beam. The lubricants formulated with these components in combination with a secondary silicone component and a photoinitator offer improved performance when compared to lubricants formulated from the prior art method of using a RTV + silicone fluid materials. The speed of the UV/EB cure of the new components makes lubricants formed from them more compatible with high speed manufacturing processes by eliminating the delay of prior art lengthy cure steps.

Lubrifiant pour dispositifs médicaux, qui contient de l'époxy de silicone et de l'éther de vinyle qui durcissent rapidement lorsqu'ils sont exposés à la lumière ultraviolette ou à un faisceau électronique intense. Les lubrifiants contenant lesdits constituants en combinaison avec un constituant silicone secondaire et un photoinitiateur offrent des performances améliorées lorsqu'ils sont comparés aux lubrifiants selon l'art antérieur contenant du silicone résistant aux variations de température (RTV) et des matières silicone fluides. La vitesse de durcissement par rayonnement ultraviolet ou faisceau électronique des nouveaux constituants rend les lubrifiants produits à base de ces constituants plus compatibles avec les processus de fabrication à grande vitesse, du fait de l'élimination du délai nécessaire pour les étapes de durcissement longues des lubrifiants selon l'art antérieur.
