Term: two-pack

In the context of painting and coatings, especially in Australia, "two-pack" refers to a two-component paint system that consists of:

1. Base (Part A) – This contains the pigment, resins, and other additives.
2. Hardener or Activator (Part B) – This is a curing agent, typically an isocyanate or catalyst, that chemically reacts with the base to form a hard, durable finish.

When mixed together just before application, the two components undergo a chemical reaction (usually a polyurethane or epoxy reaction) that results in a tough, high-performance coating.

Common Uses:

• Kitchen cabinetry
• Bathroom vanities
• Commercial joinery
• Automotive finishes
• Industrial and marine applications

Key Features:

• Extremely durable and hard-wearing
• Chemical and moisture resistant
• Glossy, smooth finish
• Requires professional application due to health and safety concerns (e.g., use of proper PPE and spray booths)

Note:

In Australia, "two-pack" is commonly used in the painting and joinery industries, especially for high-end finishes where durability and appearance are critical.
