Three Bond 1217L (Variante A)

Three Bond 1217L (Variant A) Overview

The Three Bond 1217L (Variant A) is a RTV silicone liquid gasket for vibration-related applications. Supplied in a 20 kg pail, it offers fast curing and immediate sealing in demanding environments.

As the main component, RTV silicone (oxime) is used. The gasket is characterized by a reddish-brown color and features high temperature and chemical resistance. It provides a robust barrier against coolant and oil, ensuring long-lasting seal integrity.

Suitable for vibration seals in machinery

The material is particularly suitable where constant vibrations occur — housings, pumps and gearboxes benefit from the rapid curing, resulting in a lower leak rate and reliable sealing. The coolant- and oil resistance protects components from failures caused by aggressive liquids.

Key properties and benefits

The combination of very fast curing and high durability reduces downtime and increases operational reliability. The vibration resistance ensures permanent sealing even under dynamic loads. Additionally, the coolant- and oil-resistance protects the system against leaks and corrosion.

Processing and practical notes

• Surfaces should be thoroughly cleaned and kept free of oil, grease, and dust.
• Apply the material in a sufficiently thick, uniform layer.
• Assemble to the mating surfaces for mounting; allow curing according to the product specification.

Structure and main component

Based on RTV silicone (oxime), the product provides a flexible, elastic seal that also yields to irregular surfaces and effectively prevents leaks.

Special features

Temperature resistance up to 200 °C (250 °C short-term) and a density of 1.51 g/cm³ support use in demanding applications where long-term seal integrity is required.
