Title
(EN) ORGANOSILICONE COMPOSITION, REFLECTIVE COATING, PREPARATION METHOD THEREFOR AND PHOTOVOLTAIC MODULE COMPRISING SAME
Abstract
(EN)

A silicone composition, a reflective coating and a preparation method therefor, and a photovoltaic assembly comprising the reflective coating are disclosed. The silicone composition comprises a base polymer component, a catalyst, a cross-linking agent and reflective particles, wherein the base polymer component, the catalyst and the cross-linking agent are not mixed simultaneously before use; the base polymer component comprises 100 parts by weight of a polymethylsiloxane having at least two Si-Vi bonds per molecule, 5-15 parts by weight of a hydrogenated epoxy resin or cycloaliphatic epoxy resin-modified polymethylvinylsiloxane terminated with a hydroxyl group, 10-20 parts by weight of a siloxane resin having at least two Si-Vi bonds; and the cross-linking agent is a polyorganosiloxane having at least two Si—H bonds.
