Glass Silicone Sealant

One-part, acetoxy cure, general-purpose RTV sealant
Features &Benefits:
• Cures to 100% silicone rubber
• Resistant to sunlight and weather extremes
• Fast cure, high strength
• Remains flexible; will not become brittle, crack, shrink or chalk
• Bonds to many common substrates
• Supplied is removable, reusable, resealable nozzle that saves time and sealant
Applications :
• As a bedding material, formed-in-place gasket, formed-in-place bumper
• Adhering trim, name plates, signs
• Sealing around sinks, faucets, showers, tubs, toilets and vents
• For most marine applications: sealing between hull and deck, most boat decks, windows, port lights, windshields and hatches
• 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.
• 6 mm. joint depth is recommended for joint widths between 6 mm to 12 mm.
• Joint width and depth ratio should be about 2:1.

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
Plastics Degrease using an agent recommended by plastics manufacturer

Meets or exceeds the requirements of the following specifications:
• The requirements of VOC content specifications in LEED credit EQc4.1 “Low-emitting products” of SCAQMD rule 1168.
• CE marked for EN 15651 for façade, glazing and sanitary applications

• It must not be used in totally confined spaces where sealant cannot cure due to lack of atmospheric moisture.
• Not recommended to use on porous surfaces like marble, natural stone, concrete etc.
• Because of acidic curing, it must not be used on mirrors and sensitive metals like copper, brazen, lead.
• 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 contact with water.
• Avoid from direct UV.
• Can yellow if exposed to bleach or HCL based brick cleaners whilst curing.

Storage & Shelf Life:
The shelf life is 18 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. Check MSDS guidelines for disposal and further information concerning safety.
