All of our RTV silicone sealants and adhesives have very good resistance to acids, alkaline and most industrial fluids. Intermittent exposure to fuels is fine but not resistant for continuous contact.
Common Chemical examples are Formaldehyde, Chlorine, Oil, Bio Diesel, Hydrogen Peroxide and Industrial Solvents.
A comprehensive list of compatible chemicals are listed on our downloadable PDF below :

How much will I get from a 310 ml cartridge?
6 mm x 3 mm bead = 18 Metres approx
6 mm x 6 mm bead = 9 Metres approx
Will heating RTV’s accelerate the cure time?
No,as it will eliminate the required moisture. Note – If speed of cure is important see – AG 300 – Fast curing one part sealant (6-8 hours) RTV 2 – Two hour curing 2 part sealant.
How do I prepare my surface?
Clean and de-grease metals using an industrial solvent like our Metal Cleaner or IPA. Avoid detergents as they can leave a residue Light abrasion will also be helpful prior to cleaning.
Can silicone sealants be over painted?
Sorry no – but our polyurethane’s can.
Are silicones flame retardant?
Yes our silicones will not burn unless a direct flame is applied. Some grades meet UL 94 requirements. If they do burn minimal fumes are given off so toxicity is not a concern.
