Standard Compounds
Standard Compounds
Trowal standard compounds have also the capabilities for:
- corrosion protection
- cleaning capabilities
- degreasing capabilities
Special Compounds
For special applications, where acid resistance, a minimum of foam or pickling capabilities are required, Trowal offers special compounds, containing these additional characteristics.
Powder compounds & Grinding Support
Trowal offers three polishing systems which differ in cost and the desired surface finish:
The Trowapast process
It is mainly used for high-lustre polish of rough and harder surfaces (steel, stainless steel, brass). Processing time lasts several hours. The powder concentrate to be used depends on the original surface roughness and the alloy of the work pieces.
Ball burnishing
This quick and economical polishing process yields a decorative lustre on aluminium and zinc die castings as well as on brass and stainless steel parts. For ball burnishing applications only steel media (balls, satellites, ball cones, etc.) are utilized:
GB 13 light pickling, much foam
AWS light pickling, little foam
PL 84 pH-neutral, much foam
Turbo degreasing
With very difficult degreasing problems, it is helpful to add degreasing powder at the start of the finishing process (shock degreasing):
K5 intensive degreasing, much foam
K96 adequate degreasing, little foam
Pickling Compounds
Instead of the liquid pickling compound LZ 11 an easy to handle powder can be utilized: Z1, very acidic, for pickling, decaling and de-rusting.
