Embodiment

[0227] 1) Measurement of instant tackiness or "stickiness":

[0228] Tests were performed using a PROBE TACK device (PT-1000) according to standard ASTM D2979. A cylindrical punch with a flat surface is brought into contact with the gel of the composite material to be tested (surface area in contact with the gel = 0.2 cm 2 ). The composite material is coated with 200g / m 2 A (paper-supported) flexible polyurethane film of a silicone composition as a gel precursor. Then make the punch at 100gf / cm 2 The contact time of 1 second is kept in contact with the gel under constant pressure. Next, the punch is detached from the gel at a constant speed of 10 mm / s, and the separation energy required to separate the gel from the rod is measured and expressed in mJ / cm 2 express.

[0229] 2) Evaluation of the adhesion of the silicone gel to the carrier (which is a flexible polyurethane film) ("Rub-Off") and quality of the gel

Abstract

The field of the invention is that of silicone gels which are skin-adhesive and which can be used especially in skin-adhesive articles for medical or paramedical use.

Description

technical field [0001] The present invention relates to silicone gels that may be used in breast prostheses, mattresses and pads to prevent decubitus ulcers, or for application against the skin, and more particularly: [0002] - for use in skin-adhesive dressings or parts of such dressings, especially intended for atraumatic removal from healthy skin and from wounds, or [0003] - Use in holding devices of the sensor, probe, catheter or needle type for medical accessories in contact with the skin, such as devices for securing an ostomy bag, or in parts of such devices. Background technique [0004] Silicone gels are traditionally obtained by crosslinking compositions comprising organopolysiloxanes having at least two alkenyl functional groups per molecule, polyorganohydrogensiloxanes having at least three SiH functional groups per molecule (referred to as known as "crosslinkers"), bis(hydrosilyl)organopolysiloxanes with two SiH functional groups (known as "chain extenders")...
