Aquapor

The Aquapor® series includes dust-free aluminium paste preparations consisting of aluminium powder, water and stabilizing additives.

These pastes in a soluble matrix are characterized by excellent dispersion and, at the same time, a high degree of stability in the paste suspension.

DEG

In contrast to the Aquapor® water pastes, the DEG pastes contain diethylene glycol (DEG) as a pasting substance.

These pastes are recommended for use wherever high storage temperatures and long transportation routes require excellent storage stability.

Foil grit

In contrast to "spray grit", which is produced by atomizing molten metal, the granules known as "foil grit" are produced by recycling household and packaging foils.

106/160 approx. 96 106 - 160
160/315 approx. 96 160 - 315
