Term: accelerator

In the context of painting and coatings, an "accelerator" is a chemical additive used to speed up the drying or curing process of paints, coatings, or other finishing materials. Accelerators are commonly used in two-pack (2K) systems such as epoxy or polyurethane paints, where they help reduce the time required for the chemical reaction between the base and hardener to complete.

Key Points:

• Purpose: To reduce drying or curing time.
• Common Use: In industrial, automotive, and commercial painting applications.
• Benefits:
  • Faster turnaround times.
  • Improved productivity on job sites.
  • Better performance in cold or humid conditions where drying times are naturally slower.

Example:

In a two-pack polyurethane system, an accelerator might be added to allow recoating or handling within a shorter timeframe, which is especially useful in time-sensitive projects or in cooler climates like parts of southern Australia.

⚠️ Note: Overuse of accelerators can lead to issues such as reduced pot life, poor film formation, or compromised durability, so always follow the manufacturer's specifications.

If you're a painting contractor in Australia, using accelerators can help meet tight project deadlines, especially in commercial or industrial jobs where time is money.
