Industrial Cabinets

Flexible selection for indoor-outdoor, insulation and texture needs

Industrial cabinets include electrical-control cabinets, communication cabinets, distribution boxes and other industrial equipment housings. In industrial environments, the coating must resist chemical attack, support electromagnetic-interference protection requirements and provide a good decorative finish.

Veri Coating offers pure epoxy, insulating epoxy and epoxy-polyester hybrid textured powder coatings with GT0 adhesion, more than 1,000 hours of salt-spray resistance and dielectric strength of at least 35 kV/mm, as well as high-durable polyester-HAA and standard- or high-durable polyester-TGIC textured powders with customisable weathering durability of 3-10 years.

Application notes: Welds and folded edges require thorough pretreatment, while texture film thickness, masking of grounding points and workpiece curing temperature should be controlled.

Typical Powder Coating Challenges for Industrial Cabinets

Antistatic Dust Control Indoors

In dry environments, static charge can build up on industrial cabinet surfaces and attract dust and fibres. Dark, low-gloss and coarse-textured finishes show contamination more readily and may quickly collect dust again after cleaning. This affects appearance and can increase maintenance around vents, door gaps and electrical components.

Formulation Design

Use an antistatic or static-dissipative powder coating, with conductive fillers or functional additives to control surface resistivity.
Subject to electrical-safety and appearance requirements, avoid overly coarse textures and high-surface-energy formulations to improve cleanability.

Process Control

Ensure reliable substrate grounding and stable spray voltage to reduce excessive local film build and back ionization.
Control film thickness and ensure full cure to prevent surface tack or migrating species from increasing dust pickup.
Validate cleaning intervals and dust accumulation on the final cabinet design under its intended ventilation conditions.

Validation Focus

Surface resistivity
Comparative dust-pickup test
Appearance recovery after wiping
Property retention after damp heat

Texture Uniformity

Large flat panels, formed edges and different spray directions can accentuate variations in texture, gloss and colour. Changes in particle size, the virgin-to-reclaim powder ratio, film build or oven temperature can produce locally coarse or fine texture, sagging or orange peel, and reduce batch-to-batch consistency.

Formulation Design

Use a stable textured-finish system that balances the texturing agent, resin melt viscosity and cure rate.
Control powder particle-size distribution and pigment and extender dispersion to minimise coarse particles, fines enrichment and batch variation.

Process Control

Fix the virgin-to-reclaim powder ratio and monitor particle size and flowability.
Keep gun distance, voltage, gun path and film thickness consistent, avoiding excessive local film build.
Use part-temperature profiles to confirm oven uniformity and prevent undercure or overbake from changing the texture.
