<span styReactive, good pigment wetting and thermal stability. Because it thins easily, it offers advantages in solids hold and paint washout at spray viscosity. Typical curing parameters are 30 minutes at 130°C. The product exhibits overbake stability up to 120 minutes at 190°C. Slight thermal yellowing may occur based on baking temperature and time. the Phase Capacitance Bayhytherm® 3246 and Bayhydrol ® U XP 2698 or UA 2856; compatible with blocked polyurethane dispersions such as Bayhydur® BL XP 2706 or Bayhydur® BL 2867; also compatible with amino resins such as Luwipal® 066LF, 072 or 0731) and Maprenal ® MF 904 or MF 9152).
