KAP Corrosion Control and Application Consulting – Engineering Report

The purpose of this report is to define the Isocyanates found in the Rust Bullet Product Formulas.
Isocyanates are a family of highly reactive, low molecular weight chemicals. Spray-on polyurethane products containing Isocyanates have been developed for use as protective coatings for various substrates. Preventing exposure to free Isocyanates is a critical step in eliminating health hazards, whereas bound Isocyanates do not pose health or environmental risks.
Rust Bullet Products contain diisocyanates (MDI) and MDI based polyisocyanate. These elements are well bound within the formulation of Rust Bullet Products, are not free for release into the atmosphere and are not to be confused with free Isocyanate ions.
Direct and extended exposure to temperatures reaching approximately 400˚C / 752˚F, or extreme aggressive and intentional mechanical abrasion for constant and extended periods of time may potentially cause release of Isocyanate particles. Any particles caused to be released by such methods will deteriorate rapidly once exposed to the ambient atmosphere.
The manufacturers’ recommendations and guidelines including safety precautions, personal protective equipment and proper ventilation should be followed during all coatings applications and Corrosion Control measures.
In conclusion, it is the opinion of this Coatings Engineer, the Isocyanates are bound in the polymer chains of Rust Bullet Products; these Isocyanates would remain safely bound, posing no health or environmental risk when applied according to guidelines as set forth by the manufacturer.
