Product Description

SR611 Construction & Concrete Silicone Sealant

SR611 Construction & Concrete Silicone Sealant is a non-slumping, one component, neutral cure silicone sealant. Excellent weather resistance and waterproof capability, especially suitable for weatherproof sealing of expansion joints and peripheral joints of concrete constructions. SR611 Construction & Concrete Silicone Sealant offers durable adhesion to a range of porous and non-porous surfaces including concrete, cement, masonry, PVC-U, wood, metal, etc.

FEATURES & BENEFITS:
• Good adhesion to a variety of substrates without primer, particularly suitable for weatherproof sealing of expansion joints and peripheral joints of concrete constructions.
• One component, easy to use
• Neutral curing, non-corrosive
• Non-slumping, can be used in vertical and overhead joints
• Joint movement capability ± 50%
• Excellent weatherability, virtually unaffected by sunlight, rain, snow, ozone, and water
• Reliable durability, the cured sealant remains elastic at -40°C to 150°C without hardening, cracking and chipping

APPLICATIONS:
• Weatherproof seals for expansion joints and side seams of concrete construction
• Sealing for concrete expansion joints such as roads, bridges and tunnels
• Other concrete joints require as a waterproof seal
• New construction or as a remedial or repair sealant in existing construction

USABLE LIFE AND STORAGE:
When stored at or below 27°C in the original unopened containers, it has a usable life of 9 months from the date of production.

LIMITATIONS:
• Do not use for structural glazing and use in insulated glass (IG) units.
• Not suitable for applying sealant in inclement weather
• When the sealant is applied, the bead should be lower than the road surface to prevent wear
• New concrete or asphalt pavement must be cured or air dried before using this product
• Not suitable for copper, lead, galvanized metal surfaces and polycarbonate materials
• Do not apply at temperatures below 4°C or when substrate surface temperatures exceed 50°C.
• Not suitable for frosted or wet surfaces
• Not recommended for continuous water immersion applications.
• Do not use on bituminous substrates, natural rubber, chloroprene or EPDM or on building materials which might bleed oils, plasticizers or solvents.
• Should not be used If the sealant is intended to be painted

ADHESION TEST:
SR611 Construction & Concrete Silicone Sealant has excellent adhesion to concrete and does not require primer treatment. However, due to the diversity of concrete formulations and the different surface cleanliness; we can not guarantee that the sealant will be suitable for all concretes. Small-scale adhesion tests on the site must be carried out before large-scale use in order to make a reasonable solution to ensure good adhesion.

JOINT DESIGN:
The sealant joint width should be designed to accommodate the movement capability of the sealant. When designing the joints using SR611 Construction & Concrete Silicone Sealant , the minimum width should be 6 mm. For a 6~12 mm wide joint, a sealing depth of 6 mm is required. For joints with a width of more than 12 mm, width to depth ratio of 2:1 should be used. In situations where a fillet joint is required, a minimum of 6 mm sealant bite to each substrate is recommended.

HOW TO USE:
Surface Preparation
Ensure that surfaces to be sealed are clean, dry, sound and grease-free.
Porous substrates such as concrete, brickwork, mortar, etc. must be mechanically cleaned of loose particles using a steel brush, sanding disc or any similar means.

Masking
Areas adjacent to the joints should be masked with tape to prevent contamination of the substrates and to ensure a neat sealant line. Masking tape should be removed immediately after tooling.

Priming
Primers are not usually required but might be needed for some specific substrates for maximum adherence.

Backing Materials
Where back-up material is required, closed cell polyethylene backer rod is recommended. Back-up materials provide back pressure and avoid three sided adhesion that limits sealant movement capability.

Tooling
Tool the surface of the joint immediately after sealant application to provide a smooth even finish and to ensure the sealant wets the sides of the joint. Tooling should be completed in one continuous stroke before the sealant forms a skin. Remove masking tape immediately after tooling and before the sealant skins.

Maintenance
Generally no maintenance is required, if the sealant is damaged, only the damaged part needs to be replaced. SR611 Construction & Concrete Silicone Sealant can adhere to the cured SR611 Construction & Concrete Silicone Sealant, but must be wiped off with only a preparatory solvent wipe to remove accumulated dirt.

PRECAUTIONS:
• Please read the safety data sheet of this product prior to use
• Avoid contact with eyes before curing. If contact with eyes, rinse with plenty of water and consult a doctor
• Pay attention to ventilation in the working areas
• Uncured products should avoid contact with children
