Neurtal Sealant For Curtain Wall

A neutral cure, premium performance silicone sealant, exclusively created for weather sealing and glazing application. It forms highly resistive weatherproof seal on windows and building facades.
Features & Benefits:
• Provides permanent elasticity thanks to its 100% silicone formula
• Not affected by exposure to sunlight, rain, snow and maintains it over many years
• Exceptional resistance to temperature extremes
• Very low odor  and  noncorrosive
• Excellent flexibility and adhesion to numerous porous and non-porous
• Substrates for large scale construction and glazing applications
• Fast curing, low modulus, high elasticity
• High viscosity non slump formula
• Premium weather sealing and joint sealing for walls, windows and doors
• Sealing and mounting the window and door frames
• Sealing  applications  of  marble,  stone  and  other  porous substrates
• Sealing of connection and expansion joints
• 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 20mm
Joint Depth 6mm 8mm 10mm
Efficiency /310 ml 5meters 2.5meters 1.5meters

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 then degrease as above

Degrease using an agent recommended by plastics manufacturer

Concrete and other alkaline Surfaces Brush and remove dust

Meets or exceeds the requirements of the following specifications:
• The French VOC requirements for class A+
• ISO 11600 F & G 20LM.
• CE marked for EN 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.
• 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.
• 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.
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. Check MSDS guidelines for disposal and further information concerning safety.
