K 15 is a potassium-based trimerization catalyst that promotes isocyanurate ring formation, significantly improving fire performance.

Yes, at 0.5–1.5 phr it accelerates trimerization, allowing higher line speeds (up to 20% faster).

K 15 (2-ethylhexanoate) is more soluble in polyols and gives a longer cream time, better for complex molds.

Reduce K 15 to 0.3–0.6 phr and add a small amount of a gel catalyst (e.g., MOFAN 8) to balance.

Yes, it provides good dimensional stability and fire performance; use 0.8–1.2 phr.

250–400 for PIR foam; higher index gives better flame resistance but more brittleness.

Potassium salts are mildly corrosive; avoid direct contact with aluminum; use a barrier if needed.

Blend K 15 with a potassium acetate trimer catalyst (e.g., MOFAN 2097) at a 1:1 ratio to reduce brittleness.

Yes, direct replacement; same concentration and activity.

As a solution in diethylene glycol; store in sealed container above 5°C to avoid crystallization.
