Please Call Us

Heatmate Silicone Sealant is a high modulus, reactive curing silicone sealant specifically designed for high temperature appli­cations. Heatmate cures quickly to reduce dirt pick up. It remains permanently flexible, forming a weathertight rubber-like seal. It conforms to the performance requirements of BS 5889 Type B.

 

Benefits:

  • Excellent temperature resistant: remains flexible from -50˚C - 300˚C
  • Extremely low dirt pick up - 1hour tack free
  • Orange/red colour for easy installation identi­fica­tion
  • Excellent adhesion to non-porous surfaces
  • Waterproof seal

 

Areas for use:

  • Multitude of industrial uses
  • As a gasket sealant
  • For joints and assemblies, which must be resistant to high temperatures in ducting, metal chimneys, industrial/­domestic ovens and heating appliances.

Not for use on the following areas:

  • Porous surfaces such as brick, concrete and stone.
  • In conjunction with bitumen, lead or asphalt.
  • On substrates that may bleed oils, solvent or plasti­cisers.
  • On soft metals such as lead or brass.
  • On temperatures above 285˚C, slight disco­lo­ura­tion may occur, but the joint will maintain its integrity.
  • Temperatures above 300˚C.

 

Surface preparation:

All surfaces must be clean, dry, dust and grease/oil free. All loose or flaking surface coatings, and old sealant and mastic joints, should be removed before application.

 

Application:

Surfaces must be clean (see above) and adhesion is improved by wiping the surface with white spirits. Priming is not generally required, although we always advise testing small areas prior to use.

Joint design should be as follows; Minimum width 6mm. Movement capacity will be impaired if the depth of the joint is greater than the width. For maximum movement accom­moda­tion, it is recommended that:

  1. The joint depth should be no less than 5mm.
  2. Joint depth should be 5mm for joints up to 10mm wide.
  3. Joints above 10mm in width should be half the width in depth up to 20mm and minimum 10mm for wider joints.

Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut cleanly at an angle of 45˚, with an opening slightly larger than the gap to be sealed. Apply using a standard sealant gun. Best results will be obtained by keeping an even pressure on the gun trigger and keeping the gun at a constant angle to the surface being sealed. To ensure a proper bond, always smooth the sealant down using a spatula or piece of wood wetted with linseed oil or white spirits. An improved joint appearance can be achieved by placing masking tape to both sides of the joint, removing within 5minutes of application.
