# Machinery Enclosures

Powder coatings for machinery enclosures and covers: weatherable TGIC textured polyester with sand and wrinkle finishes, 3-8 year durability and strong hiding.

Parent application: [General Industrial](https://www.vericoating.com/applications/general-industrial.md)

## Texture hiding, weatherability and coverage of complex geometries

Machinery enclosures include covers for machine tools, pump housings, compressor casings and other general industrial equipment. In industrial production environments, the coating should provide weatherability, corrosion protection, oil-stain resistance, adhesion and texture-based defect hiding.

Veri Coating offers standard-durable polyester-TGIC textured powder coatings with a range of sand and wrinkle effects, stable matt appearance, good hiding, high coating yield and customisable weathering durability of 3-8 years.

Application notes: The recommended film thickness is 70-120 um; texture consistency should be controlled, and powder coverage on folded edges, welds and recesses should be inspected.

## Typical Powder Coating Challenges for Machinery Enclosures

### Resistance to Oils, Metalworking Fluids and Cleaners

Machine-tool and equipment enclosures are routinely exposed to lubricants, cutting fluids, emulsions, degreasers and cleaning agents. The coating may soften, become tacky, stain, lose gloss, discolour or lose adhesion. Fluid pH, solvent content and service temperature can significantly alter the severity of failure.

Resistance to Oils, Metalworking Fluids and Cleaners：Exposure to oils and cutting fluids causes softening, staining or gloss loss.

**Formulation Design**

- Select a chemically resistant epoxy-polyester hybrid or pure epoxy system with a high degree of crosslinking.
- Reduce waxes and additives that are readily extracted by service fluids, and optimise the pigment, extender and resin combination for the actual fluids.

**Process Control**

- Test with the customer's actual cutting fluids, oils and cleaners at their service concentrations and temperatures.
- Ensure full cure and control film thickness; undercure markedly reduces fluid resistance.
- After exposure, assess hardness, adhesion and recovery after wiping as well as appearance.

**Validation Focus**

- Appearance after fluid immersion
- Hardness retention
- Adhesion retention
- Colour/gloss after wiping

### Abrasion and Scratch Resistance

Machinery enclosures can develop fine scratches, burnishing and local substrate exposure during assembly, handling, tool contact and routine cleaning. Dark flat areas and low-gloss finishes are particularly sensitive. Excessive hardness increases the risk of brittle fracture, so surface wear resistance must be balanced with overall toughness.

Abrasion and Scratch Resistance：Frequent contact causes scratches, burnishing and local substrate exposure.

**Formulation Design**

- Combine the resin, curing agent and wear-resistant fillers to improve surface abrasion and scratch resistance.
- Use slip additives judiciously to reduce the coefficient of friction without impairing recoat, label or screen-print adhesion.

**Process Control**

- Strengthen powder sieving and booth cleanliness to prevent particle defects from initiating scratches.
- Control film thickness and ensure full cure to prevent a soft surface caused by undercure.
- Validate scratching and wear using the actual tools, packaging materials and cleaning methods.

**Validation Focus**

- Pencil hardness
- Taber abrasion
- Scratch-resistance rating
- Appearance after impact
