Expansion Joints

  • CM-SFS-Stain-Free

    CM SFS Stain Free Silicone

    £5.85

    CM SFS Stain Free Silicone is a moisture-cured one-component neutral silicone sealant used mainly for building and glazing joints. With it moisture cure allowing it to cure at room temperature, producing a flexible seal. CM SFS Stain Free Silicone adheres to most common building surfaces without the need for primer. Fully cured movement capability of -/+50%.

    Typical Uses

    CM SFS is designed for jointing or bonding in building and glazing applications such as:

    • Precast panels and curtain wall expansion joints.
    • Windows or doors perimeter joints
    • Aluminium, wood, UPVC glazing joints.
    • Roofs and chimney joints.
    • Venting or gutter joints
    • Bonding mirrors
    • Kingspan panels

    Limits of Use

    • CM SFS is not recommended for use on materials where migration of constituents can take place, e.g. certain rubbers.
    • Not be used for jointing aquariums or swimming pools. Not ideal for permanent immersion.
    • CM SFS, once cured, should not be painted (poor coverage and adhesion of paint).
    • CM SFS is not recommended where abrasion or physical abuse will be encountered.
    • CM SFS must not be used for food contact.
    • When in contact with alkyd paints a slight yellowing can appear on the surroundings of the joint.

     

    Please see the attached datasheet for more information on CM SFS Stain Free Silicone.

  • CM Stonesil

    £5.50

    CM Stonesil is an elastic single-component silicone sealant for indoor and outdoor use, with up to 50% movement tolerance.

    Uses and Application Areas

    • Low modulus non-staining sealant with anti-fungal properties.
    • Fast cure rate.
    • Outstanding UV, weather, and ageing resistance.
    • Adhesion to numerous substrates, such as granite, composite stones, ceramic tiles, brickwork, metals, plastics also compatible with copper.
    • Low modulus (conforms to ISO 11600 F&G 25 LM).
    • Movement capability up to 50% (ASTM C920 class 50).
    • Non-staining (ISO 16938-1, ASTM C 1248).
    • Sealing joints in premier bathrooms & kitchens.
    • Glass to glass joints.
    • Sealing glass to metal.
    • Expansion joints in brickwork/stonework.
    • Marine applications.

    Joint dimensions

    The minimum joint size suggested is 5mm x 5mm for internal use and external use 10mm x 8 mm (width x depth). Maximum recommend width of the joint is 30mm x 30mm, but the joint depth should be roughly half the joint width for the ideal seal.

    Tooling

    After applying the sealant, it can be smoothed in the joint with water or with a neutral, non-staining water-based smoothing agent and a suitable tool (e.g., Bond-It Applicator Kit). Smoothing the sealant isn’t just recommended for aesthetic reasons, but it will assist in the bonding of the sealant to the substrate.

  • 791-silicone-box

    Dow Corning 791 – Box of 12 – Weatherproof Low Mod Silicone

    £54.00£55.20

    Box of 12

    Dow Corning 791 or DC 791 is a low modulus, neutral cure, alkoxy, odourless silicone sealant. It is specifically designed for the weather sealing of building components where high movement is anticipated. DC 791 adheres to a wide range of both porous and non-porous surfaces without the need for priming.

    USES

    – Perimeter pointing internally and externally around uPVC /wood and aluminium.
    – Sealing and as an adhesive onto uPVC, plastic trims and components.
    – Can be used for sealing soft metals. For instance, lead, copper and zinc.
    – For weather sealing and joint sealing on pre-formed panels, Can also be used on curtain walls and glazing sealing.
    – Glass to glass sealing and glass to aluminium sealing. Parapet and roof weather sealing applications.
    – Suitable as an expansion joint sealant.
    – Bedding and sealing of Insulated Glass units.

    CHARACTERISTICS / ADVANTAGES

    – Excellent tooling and slow skinning properties. Therefore, it is ideal for large scale construction and glazing applications.
    – Has excellent adhesion – adheres to most common surfaces. For instance, glass, metals, plastics and wood (painted or unpainted), uPVC and polycarbonate.
    – Excellent external weathering properties, therefore, can be guaranteed over many years worth of exposure.
    – High viscosity non-slump formula. In other words, it will hold it’s structure & body on even larger joints.
    – Resistant to fumed Hydrogen Peroxide and fumed Formaldehyde.

    APPLICATION INSTRUCTIONS

    PRIMER

    Dow Corning 791 does not require a primer on most common surfaces, although adhesion tests are recommended before full-scale application. However, if the joint is likely to be immersed or if adhesion is poor (especially on porous surfaces) use a Dow Corning Primer.

    SUBSTRATE PREPARATION

    Ensure that the desired application area is dry and clean, containing no grease or other contaminants. For instance, remove dust with compressed air or de-grease by using a solvent soaked pad, following by wiping with a clean cloth.

    LIMITATIONS

    – Not to be used with bitumen asphalt, neoprene and certain organic elastomers, please refer to the datasheet.
    – Can not be used in the manufacture of Aquariums.
    – Non-overpaintable.
    – Not recommended for use as a mirror adhesive.
    – Do not use on food grade applications
    – Do not use for in and around swimming pools. DC 791 is not suitable for swimming pool areas.
    – Can yellow if exposed to bleach or HCl based brick cleaners while curing.
