ISPOSIL RTV
Description
GASKET MAKER is a high-performance silicone sealant developed for sealing, bonding and repairing works where heat resistance is required. It is an ideal sealant for high temperature construction applications. It reacts with atmospheric moisture to produce a tough, elastic silicone.
- Sealing and bonding applications in automotive
- On heating systems and ovens for sealing/ tightness
- Sealing and bonding in stoves
- In heaƟ ng devices
- Gaskets in pumps and motors
- In sealing chimneys
- Other bonding and sealing applicaƟ ons where parts must perform at high temperatures
INSTRUCTIONS FOR USE
Ensure that surfaces to be sealed are clean, dry and grease free. The application temperature must be between +5 °C and +40 °C. After the application, the sealant must be tooled with light pressure within 5 minutes to spread the material against the joint surfaces and to obtain a professional finish. Excess uncured sealant may be cleaned with solvent. Cured sealant can be removed barely mechanically. 6 mm. joint depth is recommended for joint widths between 6 mm to 12 mm.
CAUTION
If inhaled in over a prolonged period or in large volumes, the acetic acid vapours released during curing may cause irritation of the respiratory system. Therefore, the application must take place in a well-ventilated area. Prolonged contact with uncured sealant must be avoided.
