Parasilico AM85-1 is a low modulus, one component silicone sealant , based on a neutral oxime curing system. Whilst multi-purpose, AM85-1 is ideal for perimeter sealing of window and door frames fabricated from most common materials. AM85-1 IS NOT BUTYL TOLERANT and should not be used for “bedding in” or any other application where it may come into contact with butyl rubber or similar compounds. This product has a more matt finish than the T type version.
