Medical adhesive applicator body

Medical adhesive applicator handle

A method for activating silicone rubber surfaces comprising steps of: i) swelling at least the surface of the silicone rubber matrix with a silicone rubber swelling solvent; ii) treating the silicone rubber matrix during or after the swelling with a solution comprising at least a reactive silane, the reactive silane comprising: a) at least one Si&#x2014;C bond and; b) at least one hydrolytically labile bond linked to at least one of the Si atoms present in the reactive silane and; c) at least one functional group F1 connected via a Si&#x2014;C bond to the same or an other Si atom present in the reactive silane, the functional group comprising electrophilic and/or nucleophilic moieties, and/or at least one functional group F2 connected via a Si&#x2014;C bond to the same or an other Si atom present in the reactive silane comprising moieties which become electrophilic or nucleophilic moieties by a mechanism selected from the group consisting of ring opening of a cyclic structure, hydrolysis, displacement or by a migration reaction; iii) drying and/or heat treating of the treated silicone rubber matrix.

Method to activate silicone rubber surfaces

Disclosed is a method to provide a metal wire with a coating system comprising a primer and a topcoat, particularly a hydrophilic, lubricious topcoat. The method comprises applying directly onto the wire metal a primer coating composition, which is an aqueous coating composition comprising a multiphase vinyl polymer, the polymer comprising a first phase having a Tg in the range of from &#x2212;20&#xb0; C. to 40&#xb0; C. and a hard phase having a Tg in the range of from 25&#xb0; C. to 120&#xb0; C. The primer has good adhesion to both the metal surface and the topcoat, and provides the eventual coating system with, inter alia, a good flexibility.
