Structrual Sealant


 
A neutral cure, premium performance silicone sealant designed for gap filling and sealing in a wide range of use in building and construction. 
 
Features & Benefits
• 100% solventless silicone
• Excellent weatherproof and UV resistant
• No Cracking or Shrinking
• Water resistant
• Very low odor and noncorrosive
• Excellent flexibility and adhesion to numerous porous and non-porous
• substrates for large scale construction and glazing applications
• Resistant to temperature extremes (-60 °C to +180 °C)
• Fast curing, low modulus, high elasticity
• High viscosity non slump formula
 
Applications :
• Weather sealing and joint sealing for walls, windows and doors
• Glass to glass and glass to aluminium sealing
• Sealing applications in kitchens and bathrooms
• Sealing  of  connection  joints   in   building   industry  (brick,  wall, concrete, PVC, wood, glass etc.)

Instructions:
• Ensure that surfaces to be sealed are clean, dry and grease free.
• The application temperature must be between +5°C and +40°C.
• In order to reduce the deformations of the joints, their depth must be much less than their width, minimum dimensions are 5x5 mm, for wider
  joints the depth should be preferably half of the width and it is adjusted by the use of a backup material.
• After the application, the sealant must be tooled with light pressure within 5 minutes to spread the material against the joint surfaces and to obtain a professional finish.
• Excess uncured sealant may be cleaned with solvent. Cured sealant can be removed barely mechanically.
• Recommended joint widths are >10 mm and < 35 mm
• Joint width and depth ratio should be about 2:1

Consumption (approx.):
Joint Width 10mm 15mm 20 mm
Joint Depth 6mm 8mm 10mm
Efficiency /300 ml 5 meters 2.5 meters 1.5 meters

Surface Preparation:
Following cleaning procedure and materials are recommended:
Glass Degrease with alcohol or MEK
Aluminium, light alloys and stainless steel Degrease with alcohol or MEK
Other Metals Lightly abrade then degrease as above
Wood Lightly abrade surface then remove dust
Plastics Degrease using an agent recommended by plastics manufacturer
Concrete and other alkaline Surfaces Brush and remove dust

Standards:
Meets or exceeds the requirements of the following specifications:
 
• The French VOC requirements for class A+
• ISO 11600 F & G 20LM
• CE marked un 15651 for façade, glazing and sanitary applications
• The requirements of VOC content specifications in LEED credit EQc4.1 “Low-emitting products” of SCAQMD rule 1168

Restrictions:
• It must not be used in totally confined spaces where sealant cannot cure due to lack of atmospheric moisture
• Not over paintable
• Do not use in conjunction with bitumen asphalt, neoprene and certain organic elastomers
• Not over paintable.
• Do not use in conjunction with bitumen asphalt, neoprene and certain organic elastomers
• It is not suitable for food contact applications
• Do not use to produce swimming pool joints
• Can  yellow  if exposed  to  bleach  or  HCL  based  brick  cleaners whilst curing
• Do not use in conjunction with bitumen asphalt, neoprene and certain organic elastomers

Storage & Shelf Life:

The shelf life is 15 months if stored in unopened-original package in a dry place at temperatures between +5°C and +25°C.

Safety & Disposal:
Inhalation of the sealant vapor for a long period must be avoided. The application area must be ventilated properly. The uncured sealant must not be contacted for a long period. Cured silicone rubber bears no risk to health.temperatures between +5°C and +25°C.
