abstract: one-component (1k) moisture-cure polyurethane primers are widely utilized in industrial metal coating applications due to their ease of application, excellent adhesion, and robust corrosion protection. the curing mechanism of these primers relies on atmospheric moisture to initiate polymerization of the polyurethane prepolymer. while this inherent feature simplifies application, it can also lead to variations...

abstract: single-component (1k) moisture-cure polyurethane (pur) primers have gained significant traction in the industrial metal coatings sector due to their ease of application, excellent adhesion, and robust corrosion protection. the curing mechanism of these primers relies on atmospheric moisture reacting with isocyanate groups present in the pur prepolymer. however, this reaction can be slow, especially...
