Thinning and plastifying agents for RTV’s and silicone sealants,

Raw material for Antifoam

Lubricating and heat protecting agents for textile threads ( synthetic sewing threads),

Ingredients in maintenance products (polishes, wax polishes, floor and furniture polishes, etc.),

Paint additives (anti-cratering, anti-floating/flooding and anti-scratching effects, etc.),

Water repellent treatment:

-of powders (for paints and plastics),

-of fibers: glass fibers,

Release agents (mould release of plastics and metal castings),

Lubricants (lubrication of elastomers or plastics on metal),

Surfactants for styrene-butadiene foam.

HCR application to reduce hardness
