-
Metal Ion Reactivity: May react with metal ions in formulation; exercise caution in compound design.
-
Dust Control: Fine powder may cause respiratory irritation; use appropriate ventilation and PPE.
-
Environmental Hazard: Harmful to aquatic organisms; prevent release to the environment.
BEST PRACTICE RECOMMENDATIONS:
-
Latex Dipping: Use at 0.5-1.5 phr for ultra-fast curing; ideal for gloves, balloons, and condoms.
-
Masterbatch Form: Prefer ZDEC-80 pre-dispersed form for better dispersion and reduced dust exposure.
-
Secondary Accelerator: Use at 0.5-2.0 phr as secondary accelerator with thiazoles (MBT) or sulfenamides (CBS) for balanced cure systems.
-
Medical Applications: Suitable for nitrosamine-free medical rubber products; verify compliance with relevant pharmacopoeia standards.
