Overview
Built for the job.
A tough, durable, rubberized aerosol (black) undercoating to protect against rust and corrosion
USC® 51333 Undercoating is a 16 oz aerosol spray formulated for rapid protection of e‑coat and plastic substrates in collision repair. The black liquid creates a uniform barrier that resists abrasion and moisture while providing a consistent base for subsequent coating layers.
With a VOC content of 365 g/L, the product delivers high solids coverage per can, reducing the number of passes required for full protection. The aerosol delivery ensures even atomization and quick flash, allowing the undercoat to become tack‑free within minutes under typical shop conditions. The low flash point of –19 °C (‑2 °F) underscores the formulation’s rapid drying characteristics.
Handling requires full PPE: eye protection, chemical‑resistant gloves, protective clothing, and a respirator in well‑ventilated areas. The material is classified as flammable, aquatic toxic, carcinogenic, and a reproductive toxin (GHS H222, H280, H319, H351, H361, H373). Follow standard first‑aid procedures—fresh air for inhalation, thorough washing for skin contact, and extended eye rinsing.
