AT3600 original German imported silica coating matte powder

Short Description:

Extinction powder AT3600 is a kind of silica extinction powder produced by gas phase process with polydimethylsilane treatment.

Fumed silica is different from wet silica, and the big difference between the two is the amount of adsorbed water and chemically bound water.

The drying loss (105 ° C for 2 hours) and burning loss (1000 ° C for 2 hours) of fumed silica were lower.

As in PU systems and varnishes, these differences are related to performance.
