The invention discloses a silicone-based pressure-sensitive adhesive composition which comprises, as a curing agent of a conventional silicone ingredient consisting of a diorganopolysiloxane and a so-called MQ siloxane resin, a 4,4′-dialkyl dibenzoyl peroxide or, in particular, 4,4′-dimethyl dibenzoyl peroxide instead of conventional organic peroxides such as dibenzoyl peroxide compounds. The inventive pressure-sensitive adhesive composition is advantageous in respect of the excellent adhesion performance which can be exhibited by curing under moderate conditions of temperature and time as compared with conventional silicone-based pressure-sensitive adhesive compositions.
本发明公开了一种硅基压敏粘合剂组合物,该组合物包含一种 4,4′-二烷基二苯甲酰过氧化物,或特别是 4,4′-二甲基二苯甲酰过氧化物,作为由二聚聚硅氧烷和所谓的 MQ 硅氧烷树脂组成的传统硅成分的固化剂,以代替传统的有机过氧化物,如二苯甲酰过氧化物化合物。与传统的硅基压敏胶组合物相比,本发明的压敏胶组合物在中等温度和时间条件下固化,可表现出优异的粘合性能。
