Base

• acetic-acid-crosslinking silicone rubber (RTV-1 silicone rubber)
• one-component, solvent-free, high-temperature-resistant

Use

• especially suitable for elastic, equalizing sealing and bonding of same and different materials
• preferably used in mechanical engineering and glass design
• leading characteristics are high temperature resistance up to +300 °C, good bonding strength on different materials, high strength, fast curing, pasty, firm
• generally, the product is used in a temperature range of -50 °C up to +300 °C; related to the application, other limits may be more reasonable
• compliant with RoHS directive 2015/863/EU

Processing

• supplied ready for use and can be processed directly from the bottle or cartridge
• DELO dispensing units are recommendable for efficient product application
• the surfaces to be bonded must be dry as well as free of dust, grease and other contaminations
• use DELOTHEN cleaners for the cleaning of bonding surfaces

Curing

• cures at room temperature under influence of humidity to a permanently elastic material
• a small amount of acetic acid is decomposed during curing (polycondensation)
• curing starts at the surface of the silicone (contact with the air humidity); a dry skin is formed already after a few minutes
• deep curing of the silicone rubber proceeds with approx. 2 mm / 24 h
