Advantages of silicone sealant

Le silicone sealant has unrivalled technical advantages: 

  • Excellent water, mould and UV resistance. 
  • Durable elasticity without cracking, even under high stress. 
  • Adhesion to a wide range of materials Glass, tiles, metal, aluminium, plastic. 
  • Resistance to extreme temperatures Some silicones can withstand temperatures from -50°C to +250°C. 
  • Easy to apply By the cartridge or in flexible pouches. 
  • Aesthetics Smooth joints in a variety of colours (white, translucent, grey, black, etc.). 

It is therefore the benchmark for flexible, watertight and aesthetic seals in all configurations. 

Building and finishing sector 

It is essential for : 

  • Bathroom and kitchen seals (around baths, washbasins and sinks). 
  • Grouting windows and glazing (against water and air).

FAQ - Silicone sealant

It's a flexible, durable sealant used to make watertight joints that resist temperature variations, UV rays and humidity, particularly in construction and industry. 

Silicone sealant is mainly used in bathrooms, kitchens, glazing, exteriorsand for applications requiring reliable sealing water, air or weather. 

  • Le acetic sealant gives off a vinegar scent on application and adheres very well to non-porous materials such as ceramics and glass. 
  • Le neutral putty is odourless and ideal for sensitive materials such as metals, plastics and concrete. 

No, most silicone sealants are not paintable. If you want a coloured joint, we recommend using a directly tinted silicone or opting for a hybrid polymer sealant. 

Yes, some specific silicone sealants can withstand temperatures ranging from -50°C to +250°C, and even higher for demanding industrial applications.
