DRY SILICONE GELS AND THEIR METHODS OF MAKING USING THIOL-ENE CHEMISTRY |
摘要 |
<p>Methods and systems are provided for a dry silicone gel. The dry silicone gel comprises a base polymer having a vinyl-silicone group and a crosslinker having thiol groups. The dry silicone gel may be made without the use of a catalyst by reacting the base polymer and crosslinker in the presence of a photo or thermal initiator. In some embodiments, the gel also comprises a chain extender having thiol groups. In certain embodiments, the dry silicone gel may comprise: (1) a hardness between 100 g and 300 g, (2) a stress relaxation between 30% and 60% when subjected to a deformation of 50% of the original size of the gel, (3) a compression set between 4% and 20% after 50% strain has been applied to the gel for 1000 hours at 70° C., and/or (4) less than 10% oil bleed out under compression of 1.2 atm after 60 days at 60° C.</p> |
