Question 1

What crosslinker is recommended for AP-6080 acrylic polyol resin?

Accepted Answer

AP-6080 is designed for use with aliphatic polyisocyanates (e.g., HDI trimer, IPDI trimer) to produce 2K PU topcoats with excellent UV stability, hardness, and chemical resistance. The NCO/OH equivalent ratio is typically 1.0–1.2. For interior applications, aromatic isocyanates (TDI, MDI) may be used at lower cost.

Question 2

What is the pot life of a 2K PU system based on AP-6080?

Accepted Answer

Pot life depends on the isocyanate type, catalyst, and temperature. With HDI trimer and no catalyst at 25°C, expect 4–8 hours pot life. With a tin or bismuth catalyst, pot life reduces to 1–3 hours. Faster cure is achieved at elevated temperatures (bake 60–80°C for 30 min).
