All surfaces must be dry and clean, free from any dust and grease or any traces of contaminants which may affect adhesion.
Degreasing is performed using a pad soaked in solvent, followed by wiping with a clean cloth. Dust is removed using oil-free compressed air.
- Glass and all glazing materials: degrease with alcohol or methylethyl ketone.
- Aluminium, light alloys, stainless steel: same procedure.
- Other metals: lightly abrade the surface then degrease.
- Wood, lightly abrade the surface then remove dust.
- Plastics : degrease using an agent recommended by the supplier.
- Concrete and other alkaline surfaces: brush and dust.
BLUESIL SLT 10B does not require a primer on most usual surfaces.
In the case of joints likely to be immersed and especially for porous surfaces, the application of a primer is recommended. Please consult us for more information.
Comment: this choice will always be made following preliminary tests carried out on the surface in question. It should preferably be applied using a soft haired brush generally, in the case of a highly absorbent surface, a second coat will be applied after the first has dried.
Expansion joints are generally subject to local regulations. Unless otherwise required, the following rule-of-thumb should be complied with: width of twice the thickness (taking account of the acceptable deformation for the sealant).
Applying the sealant:
Once an appropriate seal backing has been put in place (closed-cell polyethylene foam with surface skin or open cell polyurethane foam) the sealant should be applied taking care to ensure that the joint is completely filled. Smoothing off the seal ensures good contact between the sealant and the bonding surfaces. It should be carried out using a dry spatula before the surface skin is formed.
Areas soiled with fresh sealant may be cleaned with a dry pad or a pad soaked in a solvent. If the sealant is already cured it can be removed by scraping (e.g. using a razor blade) or using a special silicones remover like BLUESIL SILICONE REMOVER.
|BLUESIL SLT 10B OFF WHITE may be stored at temperatures between -20°C / -4°F and 30°C / 86°F for up to 12 months from its date of manufacturing.||Please consult the Safety Data Sheet of this product.|
BLUESIL SLT 10B OFF WHITE
BLUESIL SLT 10B is a one component, odourless, ready-to-use, neutral silicone elastomer (alcoxy type) suitable for weather-sealing and bonding seals in construction applications.
It cures at room temperature in the presence of air moisture to give a flexible and strong seal with low modulus of elasticity.
BLUESIL SLT 10B is available in the following colors:
- PVC White
- Off White
1 Part RTV Alcoxy
BLUESIL SLT 10B combines the advantages of a primerless adhesion elastomer and neutrality on most construction materials, including porous surfaces. Since it has low modulus of elasticity, it therefore generates low strain on bonding surfaces and gives longer life to seals.
BLUESIL SLT 10B accepts movements of up to 50% in continuous service within a wide range of temperatures.
BLUESIL SLT 10B can be used on clear glass, layered glass and all other glazed surfaces, metals, wood (painted or otherwise), PVC, polycarbonates, polymethacrylates, ABS, concrete, cellular concrete, granite, marble, etc.
BLUESIL SLT 10B does not generally stain surfaces. However, specific testing is necessary with sensitive surfaces and particularly porous surfaces (marble, stone, etc.).
Once cured, BLUESIL SLT 10B has good resistance to diluted bases and to salt mist. We can also observe good behaviour to the temporary action of common solvents and hydrocarbons with for the latter, slight swelling of the sealant during exposure. However, we can note modification to a greater or lesser extent of its characteristics under the action of acids and chemical oxidants.
Its mechanical and adhesive properties are not affected by solar radiation, rain, snow or ozone and enable it to perform its function over many years.
BLUESIL SLT 10B is specially intended to produce weather-sealing and bonding joints in the construction and glazing industries, notably for instance for:
- Traditional construction (expansion and stability joints).
- Light prefabrication (curtain walls, metal coving).
- Flooring joints (concrete slabs, motorways, airport runways).
- Caravan joints.
- Bonding of decorative panels.
- Perimeter seals in aluminium, wooden, PVC frames, etc.
- Elastic seals in glazing applications, on aluminium, wooden, PVC frames, etc.
- Heavy prefabrication (terrace, parapet wall and facade panel joints).
- Ventilation ducts, piping passages, guttering and downpipes.
- Bonding of materials subject to vibrations.
- Bonding of roof tiles.
