No matter whether they are used in bathroom joints or kitchens - silicone sealants are an important product in the DIY sector. It is a material that exists in many areas of everyday life. High-quality ingredients, such as the low-viscosity extender oils in silicone sealants, are a decisive factor and one of reasons for Haltermann Carless’s recent investment in plant technology. The goal: to produce even better, higher purity products for the base oils industry. Read more here. 

 

Modern hydrogenation unit enables excellent product properties for extender oils

Low-viscosity base oils are needed to produce silicone sealants. As extender oils, they contribute significantly to the quality of seals and ensure a silicone sealant 

  • with long term colour stability
  • maintains tensile properties without hardening
  • long term storage stability

To achieve this high sealant quality, an extender oil with high compatibility to the silicone component, lowest possible aromatic content and high purity is required.

Haltermann Carless now offers manufacturers of silicone sealants new grades of its Pilot® Oil range with improved quality properties. The new Pilot® Oil grades are ideally suited as extender oils in acetoxy and alkoxy silicone sealants.

 

Virtually aromatics-free: New Pilot® Oil grades with superior quality profile

The new hydrogenation plant at Haltermann Carless' Speyer site offers modern technology, capacity increases, high production flexibility and, above all, new product types with even higher qualities.

This is particularly evident in the case of Middle Distillates. Our new hydrogenation plant can reduce the aromatics content to an extremely low level, which further down the line reduces the risk of yellowing of the finished silicone sealant. These products are odourless, clear and colourless and are ideal for use in silicone sealants due to their excellent compatibility with the material.

New Pilot® Oil grades impress with their property profile: 

  • Good dissolving behaviour,
  • Stable to temperature variances,
  • Variable viscosities and
  • Defined boiling ranges

 

Our Pilot® 400H and Pilot® 500H are ideal for use as extender oils in silicone sealants.
