Ceresit 10T Silicone

Ceresit 10T is a one component, odourless, ready-to-use, neutral silicone elastomer (alcoxy type) intended to produce sealing and bonding joints. It cures at room temperature in the presence of air moisture to give a flexible and strong seal with medium modulus of elasticity.
Ceresit 10T adheres without a primer on virtually all surfaces found in building construction and accepts movements of 25% in continuous service within a wide range of temperatures.
Ceresit 10T combines the advantages of a primerless adhesion elastomer and neutrality on most construction materials, including porous surfaces. 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.
Ceresit 10T can be used on clear glass, layered glass and all other glazed surfaces, metals, wood (painted or otherwise), PVC, polycarbonates, polymethylmethacrylate, ABS, concrete, cellular concrete, granite, marble, etc.
Ceresit 10T does not generally cause staining of surfaces. Nonetheless, specific testing is required in the instance of sensitive surfaces, especially porous ones (marble, stone, etc.) Chemical resistance: once cured Ceresit 10T 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.
Ceresit 10T is specially intended to produce sealing and bonding joints in the construction and glazing industries.
It provides an elastic and long lasting seal in the instance of:
Heavy prefabricating and traditional masonry work
- Partition walls, panels and facades, metal framework
- Elastic seals in glazing applications, on aluminium, wooden, PVC frames, etc
- Joints for terracing, fireplaces, acroters
- Ventilation ducts, piping passages, guttering and downpipes
- Bonding of mirrors
- Bonding of materials subject to vibrations
All surfaces must be dry and clean, free from any dust and grease or anything which may be detrimental to correct adhesion of the sealant.
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 removed
Ceresit 10T 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 specific primer, ref. 12076, is recommended. Please consult us.
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 an 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 by a silicone remover.
