SEM Products 45508 Rust Trap Moisture-Cured Urethane Coating - Black

SEM Products 45508 Rust Trap is a professional-grade, moisture cross-linked urethane coating designed specifically for protecting ferrous metal surfaces from corrosion and rust. This high-performance coating chemically cures through reaction with atmospheric moisture to form a durable, flexible barrier that seals out water and oxygen.

Key Features:

• Moisture cross-linked urethane technology for superior adhesion and durability
• Specifically formulated for ferrous metals including steel and iron
• Creates a flexible, protective barrier against rust and corrosion
• Black finish provides uniform appearance while protecting substrates
• Cures through reaction with atmospheric moisture—no catalyst required
• Excellent for underbody, chassis, and frame applications
• Professional-grade formulation trusted by automotive restoration and repair specialists

Ideal for automotive restoration, rust prevention on chassis components, underbody protection, and any application where ferrous metals require long-lasting corrosion resistance. The moisture-cure chemistry ensures thorough curing even in hard-to-reach areas where air circulation is limited.
