Prepare

Degreasing of metal surfaces

Remove oils, grease, and organic residues to prepare the surface for the next treatment.

Oils, lubricants, grease, and residues from manufacturing, assembly, or operation can form a film that may interfere with subsequent treatments.

Let's talk about your project
Understand the approach

The challenges

The benefits of the treatment

01

Remove greasy residues

Target the oils, grease, and organic films associated with identified contaminants, using a formulation suited to their nature.

02

Prepare for the next treatment

Achieve a properly prepared surface before pickling, passivation, finishing, or other treatment.

03

Preserve the material

Adapt the chemistry and application conditions to the substrate and its surface condition.

Your need

When is it needed?

Degreasing is therefore a surface preparation step. Technochim adapts the chemistry and application method to the nature of the contaminants, the material, the equipment configuration, and the treatment that will follow.

  • Manufacturing oils or lubricants are present on the parts.
  • Equipment must be prepared before pickling or passivation.
  • A new installation retains residues from manufacturing or assembly.
  • A surface must be prepared before a coating is applied.

Our approach

A treatment defined for your installation

01

Identify the contaminants

Determine the nature of the oils, grease, or residues present and the materials exposed.

02

Define the treatment

Select the appropriate chemistry, application method, and conditions.

03

Degrease & rinse

Carry out the defined sequence and remove treatment residues.

04

Check the surface

Inspect the resulting condition before proceeding with further operations.

Understanding degreasing

A chemistry suited to the nature of the contaminants

Not all oils, grease, and organic contamination are treated the same way.

Select the right formulation

The choice depends on the nature of the residues, the material, the surface condition, and the treatment that will follow.

Depending on the application, Technochim can select different families of formulations: alkaline, acidic, or neutral, which may incorporate surfactants suited to the nature of the contaminants and the materials involved.

The formulation, its concentration, and its conditions of use are selected to target effective contaminant removal while controlling compatibility with the exposed materials.

Adapt the application method and rinsing

Depending on the configuration, the treatment can be carried out by immersion, circulation, or direct application, with appropriate rinsing.

Technochim expertise

Chemistry in the service of surface preparation

Degreasing does not consist of systematically applying a standard product.

Technochim links the nature of the contamination, the material, and the subsequent treatment to select the appropriate chemistry and application conditions.

  • Formulations and processes developed and controlled in-house.
  • On-site work or treatment at our facilities in Belgium and France.
  • Integration of degreasing into complete surface treatment sequences.
