Title:
PLATINUM CATALYST MIXTURE, CURABLE LIQUID SILICONE COMPOSITION AND METHOD FOR CURING CURABLE LIQUID SILICONE COMPOSITION, AND METHOD FOR PREPARING PLATINUM CATALYST MIXTURE
Document Type and Number:
WIPO Patent Application WO/2022/270366
Kind Code:
A1
Abstract:
An aerobic platinum catalyst mixture comprising a reaction mixture of a platinum-alkenyl group-containing organosiloxane complex and an organic silicon compound having at least one SiH group per molecule in an amount that makes a molar excess of hydrogen atoms bonded to silicon atoms (SiH groups) relative to the alkenyl groups in the platinum-alkenyl group-containing organosiloxane complex. The platinum catalyst mixture has the property of catalytic activity being low as a hydrosilylation addition reaction catalyst when in an oxygen-free, low-moisture content closed state in which contact with moisture (humidity) and oxygen is cut off and being activated as a hydrosilylation addition reaction catalyst by contact with moisture (humidity) and/or oxygen in the atmosphere.
