TECHSEAL RDL 911 is a two component sealant based on ‘THIOKOL’ – Polysulphide liquid elastomer. It consists of a ‘base’ compound and ‘accelerator’ (Curing Agent). RDL-911 (Pour Grade) is a pourable & self leveling material used for sealing of horizontal joints only.
When the two components are mixed together prior to application, a chemical reaction is initiated which cures instantly to a firm, flexible rubber like seal with excellent adhesion to concrete, masonry, wood, glass, acrylic and PVC plastics. It is capable of withstanding repeated extension, compression & cyclic movements without the loss of adhesion and resists deterioration by weathering, sunlight, ozone, water, salt, oils and fuels. It is far superior to all the conventional joint sealing material like bitumen, mastics, metallic channels and expansion sheets. RDL-910 (Gun Grade) is a non-sag material used for sealing of horizontal, vertical & ceiling joints RDL-911 (Pour Grade) is a pourable & self leveling material used for sealing of horizontal joints only.
- Cures at ambient temperatures to a tough, elastic and flexible rubber like material
- Bonds strongly to most of the building materials with the use of recommended primers
- Durable, remains unaffected by UV rays, ozone and weathering conditions
- Excellent reparability property
- It can be over coated by waterproofing compounds
- For Sealing of expansion, contraction & construction joints in building structure such as, buildings, roof terraces & ceilings & Sealing of dynamic structural cracks where maximum movement capability is not more than 20%
- Glazing joints of window, door frame and curtain walls
- Sealing of water retaining structure joints such as, Water tank, reservoir, aqua ducts
- Sealing of joints in traffic areas such as industrial floors, and car parking areas
- Expansion joints of retaining walls
In building structures various (different) types of joints are designed such as Butt joints, Lap joints, Fillets Joints, Expansion joints, Control joints and Glazing joints. As the joint expand, contract or experience a shear movement, cyclic movements, sealant changes the shape accordingly, but the volume of sealant remains same. Hence, in designing the joints, it is vital that the proper width-to-depth ratio is specified so that the width of the joint is consistent with the capability of the sealant to endure daily and seasonal cycles for prolonged periods. The amount of movement in a joint is dependent on the length (span), the coefficient of linear expansion of a panel section and the temperature differential of the substrate. To achieve the long-tem, effective performance the established width-to-depth ratios are determined and are given below.
1. Surface preparation is the most important step before application of sealant to get bestresults and to avoid failure.2. The joint surface must be dry, free from dust, coatings, bituminous mastics, concretecuring agents, mold release agents, oils, greases and loose particles.3. Clean the joint surface by wire brush and sanding with emery paper.4. Remove dust by compressed air or paint brush.5. Wipe out oil and grease by solvent soaked cloth (such as Xylene, Toluene or Acetone)
BACK UP MATERIALS
Insert compressible polyethylene, polyurethane, neoprene, polyethylene butyl rod as backup material to control depth of sealant in the joint and to provide support for tooling of the sealant.
Select a primer suitable to the substrate and apply two coats by brush on the sides of the joints surface at an interval of 30 minutes.
