Title (EN) CURABLE ORGANOPOLYSILOXANE RESIN COMPOSITION AND OPTICAL PART MOLDED THEREFROM
(FR) COMPOSITION DE RESINE ORGANOPOLYSILOXANE DURCISSABLE ET ELEMENT OPTIQUE MOULE A PARTIR DE CETTE COMPOSITION
Abstract:
(EN) A curable organopolysiloxane resin composition having a viscosity at 25 °C in the range of 0.001 to 5,000 Pa s, a total acid number as specified by JIS K 2501 (1992) in the range of 0.0001 to 0.2 mg/g, and light transmittance in a cured state equal to or greater than 80 %; an optical part comprised of a cured body of the aforementioned composition. The curable organopolysiloxane resin composition of the invention is characterized by good transparency, low decrease in transmittance when exposed to high temperatures, and excellent adhesion when required.
(FR) L'invention concerne une composition de résine organopolysiloxane durcissable ayant une viscosité à 25 °C comprise entre 0,001 et 5 000 Pa.s, un indice d'acidité total, tel que défini par JIS K 2501 (1992), compris entre 0,0001 et 0,2 mg/g, et une transmittance de lumière à l'état durci égale ou supérieure à 80 % ; ainsi qu'un élément optique comprenant un corps durci constitué de la composition susmentionnée. La composition de résine organopolysiloxane durcissable selon l'invention est caractérisée en ce qu'elle présente une bonne transparence, une faible perte de transmittance lors d'une exposition à des températures élevées, et si nécessaire une excellente adhésion.
