Product Description
Kafuter K-704 RTV Silicone Sealant for Electronics Insulation and Moisture Protection
Kafuter K-704 is a one-component, neutral, room-temperature vulcanizing (RTV) silicone rubber. It is non-toxic, non-corrosive, and cures by absorbing moisture from the air. It exhibits good electrical insulation, arc resistance, aging resistance, and moisture protection.
Product Overview
This product is designed for bonding, sealing, insulating, moisture-proofing, and shock absorption. It features a long shelf life, stable performance, and can adhere to various common metals and non-metallic materials.
