Outdoor Leisure Facilities

Durable protection for weather exposure and frequent public contact

Outdoor leisure facilities include park benches, fitness equipment, planters, pavilions and other public amenities. Continuous exposure to sunlight, rain and temperature changes requires reliable outdoor weatherability.

Veri Coating offers standard-durable polyester-TGIC smooth powder coatings with customisable durability of 3-8 years, at least 50% gloss retention after xenon-arc exposure, and 800-1,000 hours of salt-spray resistance. The products are 100% solids and solvent-free.

Application notes: Welds and edges require complete coverage, the recommended film thickness is 60-120 um, and low-temperature curing down to 140°C is available.

Typical Powder Coating Challenges for Outdoor Leisure Facilities

Wear and Scratching from Frequent UseContact areas lose gloss and expose the substrate, requiring a balance of hardness, toughness and wear resistance.

Wear and Scratching from Frequent Use

Handrails, steps and joints on outdoor seating, fitness installations and leisure equipment are repeatedly exposed to friction, impact and cleaning. The coating can lose gloss, scratch or expose the substrate, allowing corrosion to start at damaged areas.

Formulation Design

  1. Use a standard-durable polyester system that balances hardness, flexibility and abrasion resistance.
  2. Wear-resistant fillers and slip additives may improve surface durability, but impact, bend and intercoat adhesion must be verified in parallel.

Process Control

  1. Provide adequate effective film thickness in high-contact areas and avoid low film build at sharp edges and welds.
  2. Ensure full cure; undercure reduces hardness, abrasion resistance and chemical resistance simultaneously.
  3. Perform reciprocating rub or abrasion testing with the actual contact material and load.
Validation Focus
  • Taber abrasion
  • Scratch resistance
  • Impact/bend
  • Corrosion spread from damage
Gloss Loss and Whitening from Perspiration and SunscreenChemical contact can whiten the surface, requiring better chemical resistance and long-term exposure testing.

Gloss Loss and Whitening from Perspiration and Sunscreen

Handrails and other contact areas are repeatedly exposed to perspiration, sunscreen, skincare products and cleaners, which may cause whitening, gloss loss, softening or colour transfer. Dark matt finishes are particularly sensitive to appearance changes after chemical contact.

Formulation Design

  1. Improve the degree of crosslinking and chemical resistance of the polyester system, and select weatherable, migration-resistant pigments and additives.
  2. Balance slip and matting properties with appearance recovery after contact with sunscreen, perspiration and cleaners.

Process Control

  1. Prepare panels in the final colour, gloss and film thickness, and simulate prolonged contact with perspiration, sunscreen and cleaners.
  2. Control degree of cure to prevent undercure from causing surface softening and contaminant penetration.
  3. Define cleaning methods that avoid strong solvents or abrasive wiping materials incompatible with the coating.
Validation Focus
  • Artificial-perspiration exposure
  • Sunscreen exposure
  • Gloss/colour difference after wiping
  • Adhesion and surface hardness
