Embodiment 1
[0076] In a first embodiment, 10 g of vinyl-functionalized polydimethylsiloxane are placed in a reaction vessel and 65 g of decamethylcyclopentasiloxane are incorporated. Under constant stirring at 800 rpm, 0.5 g of methylhydrogensiloxane-dimethylsiloxane copolymer, 6.25 g of liquid polydimethylsiloxane, and 0.01 g of isopropanol were added to the reaction mixture for 10 % of hexachloroplatinic acid as catalyst and 0.05 g of 2,4,7,9-tetramethyl-5-decyne-4,7-diol as inhibitor. After a stirring time of 60 seconds, the reaction solution was ready for use. In this case, vinyl-functionalized polymethicone and methylhydrogensiloxane-dimethylsiloxane copolymer form a reactive silicone system and polydimethylsiloxane forms a non-reactive silicone oil, and decamethylcyclopentasiloxane form a diluent.
[0077] The preparation thus prepared was applied to the plastic hollow body on the inside by a wiping process and cured by heating to 175° C. for 20 seconds. In this case, a standard ...
Embodiment 2
[0079] In a second embodiment, 80 g of vinyl-functional polydimethylsiloxane are placed in a reaction vessel and 640 g of hexamethyldisiloxane are incorporated. Under constant stirring at 1000 rpm, 2 g of methylhydrogensiloxane-dimethylsiloxane copolymer, 48 g of liquid polydimethylsiloxane, 1.1 g of 1,1,3,3 - Tetramethyl-1,3-divinyldisiloxane platinum complex and 0.1 g of butynol as inhibitors. After a stirring time of 60 seconds, the formulation was ready for use.
[0080] The formulation was applied to the plastic hollow body on the inside by a wiping process and cured by heating to 250° C. for 3.5 seconds. In this case, a standard size "1 ml long" 1 ml COC syringe with an inner diameter of 6.5 mm was used as the substrate for depositing the sliding layer. Subsequently, the static and sliding coefficients of friction of the cured sliding layer were determined. Here, a V9361FM457 / 0FLNC2057 stopper from Datwyler Pharma Packaging with an outer diameter of 6.9+ / −0.1 mm was p...
Embodiment 3
[0086] In a third embodiment, 80 g of vinyl functional polydimethylsiloxane was placed in a reaction vessel and 640 g of decamethylcyclopentasiloxane was incorporated. Under constant stirring at 1000rpm, 2g of methylhydrogensiloxane-dimethylsiloxane copolymer, 48g of liquid polydimethylsiloxane, 1.1g of isopropanol in 10% Hexachloroplatinic acid was used as catalyst and 0.1 g of butynol as inhibitor. After a stirring time of 60 seconds, the formulation was ready for use.
