A low modulus, neutral cure silicone sealant

Everbuild Tecnic Silicone 825 is a low modulus, neutral cure, alcoxy, low odour silicone sealant that adheres to a wide range of both porous and non porous surfaces without the need for priming.

  • Excellent tooling and slow skinning properties for large scale construction and glazing applications.
  • Excellent adhesion - adheres to most common surfaces including glass, metals, plastics and wood (painted or unpainted), uPVC and polycarbonate.
  • Excellent external weathering properties (over many years exposure).
  • High viscosity non slump formula.
  • Resistant to fumed Hydrogen Peroxide and fumed Formaldehyde once fully cured.
Usage
  • Perimeter pointing internally and externally around PVCu /wood and powder coated aluminium.
  • Sealing and as an adhesive onto PVCu, plastic trims and components. Sealing soft metals such as lead, copper and zinc. Weather sealing and joint sealing to pre-formed panels and curtain walling, glazing sealing and draught proofing. Glass to glass and glass to aluminium sealing. Parapet and roof weather sealing applications.
  • Ideal for precast concrete and masonry products, including brick, natural stone and terracotta.
  • Suitable as an expansion joint sealant.
  • Bedding and sealing of Insulated Glass units.

Joint Design

Maximum joint width 50 mm, max depth 50 % of joint width

Joint widths are calculated as in BS6213:

Width=(M x 100)/F + M

Where M = movement and F = movement accommodation Factor

For maximum movement accommodation, it is recommended that:
1. The sealant joint depth should be no less than 5 mm.
2. Joint depth should be 5 mm for joints up to 10 mm wide.
3. Joints above 10 mm in width should be half the width in depth up to 20 mm and minimum 10 mm for wider joints.
Joint depth may be adjusted to the correct size using EVERBUILD JOINT BACKER ROD.
