APPLICATIONS
 
 
• Dow Corning® 799 EU Glaze and Go Neutral Sealant is a one-part neutral curing, low modulus silicone sealant specially formulated for glazing and weathersealing of windows.
• Dow Corning 799 EU Glaze and Go Neutral Sealant offers durable adhesion to most porous and non-porous substrates including masonry, brick, aluminium, PVC, glass and glazed surfaces.
• Dow Corning 799 EU Glaze and Go Neutral Sealant is mold and mildew resistant.
 
PREPARATION:
 
 
Surfaces must be cleaned, dry and free from grease and dust. Non-porous surfaces, such as aluminum, glass etc., should be cleaned with a suitable solvent for the substrate.
Porous substrates such as concrete, brickwork, mortar, etc. must be mechanically cleaned from loose particles using a steel brush, sanding disc, or any similar means. The use of a primer is recommended to obtain durable adhesion performance on such porous substrates, or if water immersion is expected to occur during the service life of the assembly. Otherwise, primers are not usually required but might be needed for some specific substrates to achieve optimum adhesion.
Priming This product adheres to a variety of porous and non-porous substrates.
Users must carry out their own tests due to the great variety of substances. In many cases, adhesion can be improved by pretreatment of the substrates with a primer:
• Dow Corning® 1200 OS for metals.
• Dow Corning® Primer P for concrete and brick.
 
 
HOW TO APPLY:
 
Dow Corning 799 EU Glaze and Go Neutral Sealant is ready to use. After suitable joint preparation and masking, the sealant is gunned into place and tooled within 5 to 10 minutes using a spatula or tooling instrument.
 
After tooling, tooling aids and masking tape should be immediately removed. Dow Corning 799 EU Glaze and Go Neutral Sealant cures reacting with atmospheric moisture. Typical properties are given for testing conditions of 23ºC (73.4ºF) and 50% R.H.
Uncured material can be removed by using a solvent. Cured material may be removed by abrasion or other mechanical means.
Joint design The sealant joint width should be designed to accommodate the movement capability of the sealant. In general, the minimum joint width should be 6mm. For joints between 6-12mm wide, a seal depth of 6mm is recommended.
For joints above 12mm wide, a width to depth ratio of 2: 1 should be used, up to a maximum depth of 12mm. For joint dimensions greater than 25mm, please contact Dow Corning’s Technical Service Department.
In situations where fillet joints are needed, a minimum of 6mm sealant bite to each substrate is recommended. Bond beaker tape or a backer rod should be used as back-up material to provide backpressure and avoid three-sided adhesion that limits sealant movement capability.
