Details

EVERFLEX SILICONE 900N is a low modulus, Neutral, oxime cure RTV silicone sealant that has excellent adhesion to a wide range of both porous and non porous surfaces without the need for priming.

 

Benefits

  • Excellent adhesion - adheres to most common surfaces including glass, metals, plastics and wood
  • Low dirt pick up - important in PVCu  work
  • Excellent external weathering properties.
  • Mould resistant
  • Certified under the harmonized European standard EN15651 for façade, cold climate and sanitary applications in compliance with the Construction Product Regulation

 

Areas For Use

  • Perimeter pointing internally and externally around PVCu /wood and all other window frames.
  • Sealing and as an adhesive onto PVCu, plastic trims and components.
  • Suitable as an expansion joint sealant.
  • Weather sealing and joint sealing to pre-formed panels.
  • Sealing soft metals such as lead, copper and zinc.
  • General draught proofing, including repair work over existing sealant..
  • Parapet and roof weather sealing applications.

 

Surface Preparation

The surfaces to be must be clean, dry and free from dust, grease and other contaminants. As quality of plastics can vary, always cary out adhesion tests prior to large scale use.

Improve adhesion by wiping surface with EVERFLEX PVC SOLVENT CLEANER (pvc) or white spirits (painted surfaces). Priming is generally not required, although we always advise testing small areas prior to use.

Joint design should be as follows:

Minimum width: 5mm. 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

 

For deep joints, reduce depth by using  EVERFLEX  FIX AND FILL FOAM or a suitable joint backer rod.

All joints should be designed so that the seal is placed in a position which does not retain water or form a water trap.  Triangular fillets should be no less than 12mm across the face and should be finished with a flat or convex face. 

 

Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut at an angle of 45owith 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 trigger and keeping the gun at a constant angle to the surface being sealed. To ensure a proper bond, always smooth the sealant down with a spatula or piece of wood  An improved joint appearance can be achieved by placing masking tape to both sides of the joint, removing within 5 minutes of application.

 

Application

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. Smooth down within 10 minutes of application using a wetted spatula, piece of wood or wetted finger. Any excess sealant can be removed with white spirit.
