Sealing joints and gaps is one of man's oldest craft activities. Today, silicone sealants are among the first choice and are indispensable in the construction industry and for DIY enthusiasts - whether for windows and doors, in the bathroom or the kitchen. This important material convinces with many special properties. Our Pilot® extender oils play an important role in this. You can find out exactly which ones in our article.
Silicone sealants have to fullfil a lot of requirements
Silicone sealants may be unremarkable, but their added value is enormous. Wherever joints, gaps and cracks between different materials need to be filled and sealed, silicone sealants offer a clean and durable solution. The variety of applications for both interior and exterior construction is high: in the sanitary area, the kitchen, for sealing doors, windows and window sills and much more. The sealant protects against dirt and moisture and, thanks to its permanently elastic properties, is ideally suited to withstand and compensate for building movements.
High requirement profile for silicone sealants:
- Curing on the spot due to atmospheric humidity
- Weather-resistant
- Water-repellent and waterproof
- UV- and temperature-resistant
- Corrosion-free (for application on metallic substrates)
- Resistant to ageing
- Good adhesion properties (can be applied to almost all substrates)
- Flexible and tear-resistant during application
- High insulating effect against electricity
Tailor-made Pilot® extender oils allow for high-quality silicone sealants
Silicone seals become perfect with low-viscosity base oils. These special products with narrow boiling points are used as so-called extender oils in silicone sealants. In order to meet the high requirements of the sealant, these extender oils must show high quality characteristics.
With its Pilot® extender oils, Haltermann Carless offers particularly high-quality products that optimally support the properties of silicone sealants.
Benefits of our Pilot® extender oils:
- Lowest aromatic content
- Low odour formation
- Excellent anti-aging properties
- UV stability
- Colour stability
Pilot® extender oils enable a long service life for the cured sealant - for us, this means a sustainable product, satisfied customers and convinced end users.
