  Premium performance for virtually every repair.
  Quality resin is essential to creating safe, durable, better-looking windshield repairs. It fills the break, bonds with the glass as it cures, and helps restore the structural integrity of the windshield.

  Black Label takes that foundation further. ONYX and EMERALD feature advanced polarized cloaking technology—worldwide patent pending—designed to reduce reflectiveness and help the repair disappear into the windshield.

  Both premium formulas can handle nearly any repair. ONYX excels in tight, intricate damage, while EMERALD provides controlled flow for larger, more open breaks.

  Two premium formulas. One Black Label system.

  Exceptional strength for exceptional repairs.
  Black Label Resins are premium professional formulas engineered to provide reliable performance, control, and durability on every repair.

  Black Label resin is 34% stronger than a competitor’s resin, delivering enhanced repair performance when the finished result matters most.

  Both ONYX and EMERALD are formulated to provide consistent results across changing repair conditions and climates.

  Dependable throughout the entire job.
  Black Label resins provide reliable performance and control from injection through the completed cure, helping professional technicians produce consistent results.

  Both premium formulas are designed for year-round use. EMERALD’s controlled flow is especially helpful on warm glass, where it helps reduce flowering.

  Two formulas. Two distinct sweet spots.
  ONYX — Maximum Cloaking Technology
  The go-to formula for everyday repairs. Its easy-flowing performance excels in tighter damage, including combination breaks, star breaks, fine legs, and short cracks.

  EMERALD — Color Matched Precision
  A slightly thicker formula created for larger open repairs, bullseyes, drilled repairs, and other damage where greater flow control is beneficial.

  Both formulas are highly versatile. The difference is not where they can be used, but where each formula delivers its greatest advantage.
