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.
