When you get up

HDK® lets you squeeze your toothpaste smoothly onto the toothbrush without it becoming runny. Pyrogenic silica is a compounding aid, which gives toothpaste the required paste stiffness. It improves product stability, prevents separation and acts as a thickener.

At breakfast

Milk stays cold in the refrigerator partly thanks to HDK®: With its excellent thermal insulation, pyrogenic silica is used in highly efficient thermal insulation systems – and can be found in vacuum insulation panels of refrigerators, but also in stovetops.

Driving in the car

You can thank HDK® for your car’s immaculate paintwork: As a rheology additive for automotive clear coats, HDK® provides a mirror finish by optimizing leveling, and has outstanding transparency in the paint.

Energy supply

We encounter adhesives containing HDK® in many industrial applications – such as wind turbines. HDK® modifies the rheological and thixotropic properties of adhesives, prevents sedimentation and makes processing easier.

At work

Pyrogenic silica is a key constituent of the dry toners used by laser printers and photocopiers. It gives you control of the crucial properties of toners, such as flowability, triboelectric charging and stability – during storage as well as during use.

At play

When you are relaxing on your yacht, pyrogenic silica is probably on board, too. HDK® has the important role of controlling the flow properties during the hand lay-up process for manufacturing composites.

At dinner

We can thank HDK® for the fact that salt flows freely even after long storage, and spice powder can be easily sprinkled over meals. As a flow aid, pyrogenic silica helps ensure that powders and granules are free flowing.

Going to bed

It’s quite likely that you consume HDK® with your daily tablet. Pyrogenic silica is an anticaking agent in many pharmaceutical powders. The high purity of HDK® pyrogenic silica helps ensure the safety of patients and consumers.
