Application

Suitable for sanitary applications.

Description

One part, high modulus, acetoxy cure silicone sealant which cures rapidly, on exposure to moisture vapour, to form a resilient elastic silicone rubber.


Features and benefits:

  • Can be used for sealing aluminium sheets and components.
  • Contains a fungicide to help reduce mould growth.
  • Not recommended for overpainting, or use against metal surfaces or natural stone.
  • Very good UV resistance.
  • Anticipated service life of over 25 years.
  • Health and safety: Avoid prolonged skin contact.
