DOWSIL 688 Glazing and Cladding Sealant is one-part neutral cure, construction grade sealant that easily extrudes in any weather. It quickly cures at room temperature by reaction with moisture in the air to form a durable, flexible silicone rubber seal. One-part neutral cure silicone sealant designed for a wide range of glazing, weather-sealing and professional caulking applications. It will bond to form a strong weatherproof seal on most common building materials. It has excellent unprimed-adhesion to most construction materials.

DOWSIL 688 Glazing and Cladding Sealant is a one-part neutral cure silicone sealant designed for a wide range of glazing, weather sealing and professional caulking applications. It will bond to form a strong weatherproof seal on most common building materials.
How to Use:
Clean all joints and glazing pockets, removing all foreign matter and contaminants such as grease, oil, dust, water, frost, surface dirt, old sealants, or glazing compounds and protective coatings.
Application Method -
Install backing material or joint filler, setting blocks, spacer shims, and tapes. Areas adjacent to joints may be masked to ensure neat sealant lines. Primer is generally not required on non-porous surfaces. It is recommended that a field test be carried out prior to application. To confirm optimum adhesion on either a porous or non-porous surface, adhesion testing should always be carried out prior to the commencement of any project. Please contact your local sales office for specific advice.
Apply DOWSIL 688 Glazing and Cladding Sealant in a continuous operation using a positive pressure. Tool the sealant with light pressure to spread the sealant against the backing material and joint surfaces before a skin forms. The applied sealant should be tooled and masking tape removed before the sealant has formed a cured skin.
Before handling, read product and safety data sheets and container labels for safe use, physical and health hazard information
DOWSIL 688 Glazing and Cladding Sealant is not recommended for use in continuous water immersion, nor for below ground or other joints where excessive abrasion and physical abuse are encountered. It should not be used:
To build materials that bleed oils, plasticizers, or solvents - materials such as impregnated wood, oil-based caulks and certain green or partially vulcanized rubber gaskets and tapes.
To copper or copper containing building materials.
To surfaces in direct contact with food. This sealant has not been tested to determine its status under Federal Food and Drug Administration regulations.
To uncured sealant other than DOWSIL 688 Glazing and Cladding Sealant. Sealant with different cure chemistry, such as one part structural sealants, should be fully cured before DOWSIL 688 Glazing and Cladding Sealant is applied.
Usable Life And Storage:
Store in original unopened containers in a dry place. Storage temperature should not exceed 30°C. DOWSIL 688 Glazing and Cladding Sealant has a shelf life of 12 months from date of manufacturing as noted with """"use by"""" date printed on the packaging.
