BoPin 850 High-Strength Construction Adhesive

BoPin 850 is a single-component, moisture-curing MS polymer adhesive engineered for high-strength panel bonding and heavy construction assembly applications. Available in two performance variants to suit different installation requirements: the standard grade delivers exceptional tensile strength of 3.3 MPa with good elongation for applications where flexibility is needed alongside strength; the instant-grab grade provides immediate anti-slip resistance on vertical surfaces with fast skin formation of 5 minutes — critical for large-format stone and sintered panel installations where temporary mechanical support would otherwise be required. Both variants cure at room temperature to form a strong, flexible rubber with good ageing resistance and long-term durability.

Main Benefits
  • Exceptional tensile strength — up to 3.3 MPa, among the highest in the MS polymer range
  • Instant-grab variant — 5-minute skin formation provides immediate anti-slip resistance on vertical panel applications
  • Good initial grab — resists panel displacement during cure without mechanical support
  • Good elongation (standard grade: 430%) — accommodates minor differential movement between bonded panels
  • High shear strength — 2.5 MPa resists sustained vertical panel load
  • Solvent-free, low-odour formula — suitable for interior and exterior applications
  • Good adhesion to sintered stone, natural stone, glass, aluminium composite panels and ceramics
Adhere To
  • Sintered stone and ultra-compact surface panels
  • Natural stone — marble, granite and engineered stone
  • Aluminium composite panels (ACP)
  • Glass and coated glass
  • Ceramic and porcelain
  • Metal panels and profiles
Application Areas
  • Standard Grade (3.3 MPa / 430% elongation):

    • Sintered stone panel bonding and joining
    • Natural stone panel splicing and assembly
    • Large-format panel installation where flexibility is required alongside strength

    Instant-Grab Grade (3.2 MPa / 150% elongation):

    • Exterior wall panel and cladding bonding
    • Interior decorative panel and facing board installation
    • Skirting board, mirror and ceramic component bonding
    • Swimming pool surround panel bonding (above waterline only)
Package
  • Standard Grade: 300ml cartridge — 24 units per carton / 590ml sausage pack — 20 units per carton
  • Instant-Grab Grade: 300ml cartridge — 24 units per carton
  • Available colors upon request

  • Surface Preparation — Ensure all bonding surfaces are clean, dry and free from dust, grease, release agents and loose particles. For polished stone and smooth metal surfaces, wipe with isopropyl alcohol and allow to dry completely. Remove any existing adhesive or coating from the bond area.
  • Application — Load cartridge into sealant gun. Apply adhesive in parallel beads or a serpentine pattern to one bonding surface. For vertical panel applications using the instant-grab grade, work in manageable sections within the 5-minute skin formation window.
  • Assembly — Press panel firmly and evenly into position immediately after adhesive application. For the standard grade, temporary support may be required for vertical applications during initial cure. For the instant-grab grade, immediate anti-slip resistance reduces temporary support requirements.
  • Curing — Avoid loading or disturbing bonded panels for at least 24 hours. Full mechanical properties develop after 7 days.
  • Cleanup — Remove uncured product with a suitable solvent before skin formation. Cured product must be removed mechanically.
Limitations
  • Not suitable for PE, PP or PTFE surfaces
  • Not suitable for structural glazing applications
  • Not suitable for continuous water immersion
  • Not suitable for surfaces containing plasticiser, oil or solvent residues
  • Do not apply when substrate temperature is below 4°C or above 40°C
  • The instant-grab grade has lower elongation (150%) — not suitable for joints subject to significant movement
Tips
  • For large sintered stone panels on exterior facades, consult a structural engineer to confirm adhesive bead pattern, spacing and panel fixings comply with applicable wind load requirements
  • The instant-grab grade (5-minute skin) is specifically designed for vertical panel bonding — use this grade when working on wall panels and facades to minimise temporary support time
  • The standard grade (430% elongation) is better suited for panel joining and splicing applications where differential movement between panel sections must be accommodated
  • Always conduct an adhesion test on actual project materials before full installation — stone surface treatments and panel coatings vary and may affect bond strength
  • Store cartridges upright in a cool, dry location away from heat and direct sunlight
