Dowsil 799 Glaze & Go Silicone Sealant Clear 310ml

Dowsil 799 Glaze & Go Silicone Sealant Clear 310ml

The Dowsil 799 Glaze & Go Silicone Sealant is a premium clear silicone product designed for high‑performance sealing in glazing, construction, and industrial applications. Packaged in a convenient 310 mL cartridge with dimensions of 235 mm × 50 mm × 50 mm, this sealant delivers exceptional adhesion, flexibility, and durability across a wide range of substrates.

Key Characteristics

• Clear Finish: Provides an invisible seal that blends seamlessly with glass, metal, ceramic, and many plastics.
• High Flexibility: Maintains elasticity over a temperature range of –40 °C to +120 °C, accommodating thermal expansion without cracking.
• Excellent Adhesion: Bonds strongly to glass, aluminum, stainless steel, PVC, polycarbonate, and other common building materials.
• Waterproof & Weather‑Resistant: Forms a continuous barrier against moisture, rain, and UV exposure.
• Low VOC: Meets stringent environmental standards for indoor air quality.
• Easy Application: Comes in a ready‑to‑use cartridge with a smooth dispensing tip that allows precise control.

Composition & Chemistry

The sealant is formulated from a high‑purity polysiloxane resin combined with a proprietary crosslinking system. This chemistry ensures rapid curing at room temperature while preserving long‑term resilience. The silicone matrix incorporates small amounts of silane coupling agents that enhance adhesion to inorganic surfaces, and a controlled amount of catalyst that initiates the condensation reaction upon exposure to atmospheric moisture.

Application Areas

• Glazing: Ideal for window frames, skylights, glass doors, and curtain walls where a clear seal is essential.
• Construction & Building Envelope: Seals joints between cladding panels, metal trim, and other façade components.
• Industrial Equipment: Used in piping systems, pressure vessels, and equipment housings that require a flexible, waterproof seal.
• Automotive & Marine: Suitable for sealing windshields, windows, and exterior panels where exposure to harsh environments is common.

Installation Procedure

1. Surface Preparation: Clean the joint area with a solvent or detergent. Remove dust, grease, and old sealant residues. Ensure surfaces are dry before application.
2. Cartridge Loading: Insert the cartridge into the dispensing gun. Prime the nozzle if necessary to eliminate air bubbles.
3. Application: Apply a continuous bead of sealant along the joint, maintaining uniform pressure to achieve even coverage.
4. Tooling (Optional): Use a silicone‑compatible tool or a wet finger to smooth the bead and remove excess material. Tooling improves adhesion and aesthetics.
5. Curing: Allow the sealant to cure at ambient temperature for a minimum of 24 hours before exposing it to water, wind, or mechanical stress.

Curing & Performance

The Dowsil 799 cures through a moisture‑activated condensation reaction. Under typical indoor conditions (20–25 °C, 40–60 % RH), the sealant reaches full strength within 24 hours and achieves maximum flexibility after 48 hours. The cured material exhibits excellent resistance to abrasion, chemical attack, and UV radiation.

Compatibility & Substrate List

Safety and Handling

• Ventilation: Use in well‑ventilated areas. The product emits minimal fumes.
• PPE: Wear gloves and eye protection during handling to prevent skin irritation.
• Storage: Keep the cartridge sealed and stored at temperatures between 5 °C and 35 °C.
• Disposal: Dispose of unused material in accordance with local hazardous waste regulations. Do not pour down drains.
