Production Process

Our vertically integrated manufacturing ensures precision at every stage:

  1. Raw Material Synthesis:
    • Polymerization reactors produce acrylic copolymers and SBC elastomers.
    • Tackifiers derived from renewable rosin ensure consistent peel strength11.
  2. Formulation & Compounding:
    • Proprietary blends of resins, plasticizers, and stabilizers optimize adhesion and aging resistance.
    • In-line QC checks validate viscosity, tack, and cohesion.
  3. Coating & Curing:
    • Solventless slot-die coating minimizes waste.
    • UV curing tunnels enable instant cross-linking for high-performance tapes.
  4. Slitting & Packaging:
    • Automated systems convert jumbo rolls into custom widths (10mm–1,500mm).
    • Anti-static liners protect pressure sensitive adhesives integrity during transit.
