Loctite SI 598 High Performance Siliconeasket Black - 300ML Cartridge

Loctite SI 598 Silicone Gasket is a metallic black, 1-part, oxime silicone paste sealant. This product is designed for room temperature vulcanisation, curing upon exposure to air moisture to form a durable, flexible silicone rubber gasket. Ideal for gasket replacement or dressing, Loctite SI 598 is an essential tool for automotive and industrial maintenance. The sealant enhances the load-bearing and shock-absorbing properties of the bond area and remains effective when exposed to common automotive engine oils.

Loctite SI 598 Silicone Gasket provides outstanding resistance to ageing, weathering, and thermal cycling, ensuring long-lasting performance without hardening, shrinking, or cracking. It is particularly well-suited for applications such as sealing oil pans, transmission pans, valve covers, timing gear covers, and differential covers. With an operating temperature range of -54°C to 260°C, Loctite SI 598 maintains its integrity even under extreme conditions.

How to use Loctite SI 598 Silicone Gasket Black:

1. For best results, bonding surfaces should be clean and free from grease and other contaminants. We recommend a general purpose cleaner such as Loctite SF 7063.
2. Moisture curing begins immediately after the product is exposed to air. Assemble parts within a few minutes after the product is dispensed.
3. Allow for full curing time before subjecting to heavy service loads. Full properties will develop over 72 hours.

Storage

Store Loctite SI 598 in the unopened container in a dry location. Optimal storage: 8°C to 21°C. Storage below 8 °C or greater than 28 °C can adversely affect product properties.
