BoPin 820 Multi-Purpose Construction Adhesive

BoPin 820 Multi-Purpose Construction Adhesive

BoPin 820 is a single-component, moisture-curing MS polymer adhesive and sealant formulated for general construction bonding and sealing applications across a wide range of substrates. Based on modified silane polymer technology, it cures at room temperature to form a strong, flexible rubber with excellent adhesion to concrete, glass, aluminium, stainless steel, aluminium composite panel, ceramic and timber — typically without primer. The medium-hardness cured body provides a good balance of bond strength and flexibility suitable for general construction joints, panel installation and bonding applications where a versatile, paintable, solvent-free adhesive is required.

Principaux avantages

Excellent adhesion to a wide range of substrates including concrete, glass, aluminium, stainless steel, ACP, ceramic and timber — typically without primer
Paintable after cure — compatible with most water-based and solvent-based paint systems
Solvent-free, low-odour formula — suitable for use in occupied interior and exterior spaces
Good elongation (220%) — provides flexibility to accommodate minor joint movement
No shrinkage during cure
Suitable for both interior and exterior applications
Shelf life 12 months

Préparation de la surface — Ensure all surfaces are clean, dry and free from dust, grease and loose material. For best results on smooth non-porous surfaces such as glass and polished metal, wipe with isopropyl alcohol and allow to dry before application.
Application — Cut cartridge tip at 45°, load into sealant gun and apply with steady, even pressure. For bonding applications, apply in parallel beads or a serpentine pattern to the bonding surface. Press components together firmly within the skin formation time.
durcissement — Allow to cure at room temperature with adequate ventilation. Avoid disturbing bonded components 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.

Limites

Not suitable for PE, PP or PTFE surfaces
Ne convient pas à une immersion continue dans l'eau
Ne convient pas aux applications de vitrage structurel
Not suitable for surfaces containing plasticiser or solvent residues
Do not apply when substrate temperature is below 4°C or above 40°C

Conseils

The medium hardness (Shore A 55) and good elongation (220%) make this product well suited for general construction bonding and sealing — for high-strength structural panel bonding where tensile strength above 3.0 MPa is required, consider BoPin 850
For ACP panel installation, apply adhesive beads at regular intervals across the panel back — bead spacing and pattern should be determined by panel size and wind load requirements
Paintability is a key advantage — allow full cure before applying paint for best adhesion results
Store cartridges upright in a cool, dry location away from heat and direct sunlight
