Blocked Isocyanate Curing Agent ICASON1530
Crosslinking agent for polyurethane powder coatings
Brief Introduction:
ICASON1530 is a polyisocyanate adduct used in combination with different hydroxyl functional resins, due to the caprolactam blocked NCO-groups,it have the properties of excellent weathering ability, excellent flow, good storage stability and good mechanical properties. So, it's mainly used to produce the leveling coating film.
Specification:
Appearance: Pale Nco-equivalant(total): 14.8-15.7%wt
Granules Melting range(℃): 62-82 Glass transition temp(℃): 41-53
Application:
1.Crosslinker and polyester are used in equivalent amounts. Empirically determined under indexing (up to NCO: OH=0.8:1) yields economical coatings witch exhibit excellent physical properties meeting the required performance profile. Up to 1% by weight degasseris often used in pigmented powder coatings to minimize surface imperfections.
2. Curing condition (metal temperature): 200℃/12-15 minutes.
