2598
Overview
2598 Silicone Gasketing Sealant
is a single-component, low-strength, oxime-cure paste silicone with thixotropic properties, curing via ambient moisture at room temperature. It offers excellent aging resistance, weatherability, and thermal cycling performance, remaining non-hardening, non-shrinking, and crack-resistant. Suitable for bonding various materials, it is widely used for flat sealing in automotive components, internal combustion engines, general machinery, and electrical equipment.
