Minimal Air Bubbles and Flame Retardancy in Decorative Polyurethane Systems

Polyurethane is widely used in decorative applications, from ceiling elements to furniture accessories. In such products, two technical factors are just as critical as appearance: bubble-free surface quality and fire resistance. Pluskim's decorative PU systems are engineered to deliver flawless visual results and compliance with fire safety standards.

1. Minimal Air Bubbles: A Perfect Finish

Air bubbles compromise both visual aesthetics and coating performance. Pluskim decorative systems offer:

  • Low gas release and stable cell structure
  • Complete mold filling without surface defects
  • Balanced reactivity to prevent trapped air
  • Suitable for vacuum and open molds with excellent uniformity

2. Flame Retardancy: Safety and Compliance

Since decorative PU is used indoors, fire behavior is critical. Pluskim's formulations provide:

  • B2 or optionally B1 flame rating
  • Enhanced with flame-retardant additives
  • Compliance with EN 13501-1 and similar standards
  • Low smoke generation and non-dripping behavior

Application Areas

  • Ceiling roses, moldings, wall panels
  • Furniture trims and frame parts
  • Column claddings, mirror frames
  • Base for gilding, lacquer, and high-end finishes

Ideal for parts where appearance and structural performance must go hand-in-hand.
