Bison Poly Max White Express 425 ml

Bison Poly Max Express (425 ml): Universal Crystal Clear Adhesive & Sealant

Key Properties and Performance Advantages

• Invisible, Crystal-Clear Finish: First, the compound cures completely transparent. As a result, it produces unnoticeable bond lines on visible surfaces such as glass, mirrors, decorative trims, and polished stone.
• Rapid Grip and High Final Strength: In addition, the formula offers express handling strength with high final load-bearing capacity. Therefore, mounted fixtures remain firmly anchored over the long term.
• Permanent Elasticity (Non-Shrinking): Furthermore, it is formulated as 100% adhesive, which means it will not shrink, crack, or pull away over time. Because it stays permanently flexible, it easily absorbs natural structural vibrations and thermal expansion.
• All-Weather Durability: Moreover, the cured bead resists UV exposure, water immersion, mold, and temperature extremes ranging from -40°C to +100°C. Consequently, it performs reliably in harsh exterior climates as well as moisture-heavy indoor spaces.
• Safe and Primer-Free Formulation: Similarly, it delivers exceptional adhesion without requiring primer, even on slightly damp substrates. Because it is completely solvent-free, acid-free, and odorless, it is safe and comfortable to apply indoors.

Wide Field of Applications

• Heavy-Duty Bonding: For instance, it bonds glass, natural stone, concrete, plasterwork, ceramic tiles, iron, aluminum, zinc, steel, stainless steel, wood, chipboard, cork, and mirrors.
• Architectural Fixing: Additionally, it securely mounts skirting boards, timber frameworks, laths, window sills, doorsteps, roof fascias, gypsum boards, polystyrene ornaments, and insulation panels.
• Watertight Sealing: Furthermore, it seals structural connecting joints along plastic window frames, skylights, chimneys, roof gutters, and roof fascias, while also sealing seams between window panes and frames.
• Substrate Exclusions: However, it is not suitable for polyethylene (PE), polypropylene (PP), PTFE, polyamide (nylon), acrylic glass (Plexiglas), or bitumen.

Step-by-Step Application Guide

1. Surface Inspection: First, make sure the target surfaces are clean and free of dust and grease. Although substrates can be slightly moist, completely dry surfaces optimize final bond strength.
2. Nozzle Preparation: Next, prepare the cartridge nozzle according to the task. For bonding and fixing, cut the nozzle tip to an opening diameter of at least 0.5 cm. For joint sealing, cut the nozzle slantwise to match the desired joint width.
3. Dispensing for Bonding & Fixing: Afterward, apply the adhesive in vertical stripes or spots spaced 10 cm to 40 cm apart, ensuring adhesive is applied along all outer edges and corners. Then, join the materials within 10 minutes and press firmly or tap lightly with a rubber mallet. If you are mounting heavy elements under tension, support or clamp them for 24 hours.
4. Dispensing for Joint Sealing: Alternatively, inject the sealant evenly into the seam and tool it smooth within 10 minutes using a joint smoother, wet putty knife, or finger wetted with lemon-free soapy water. Tool vertical joints from the bottom upward to ensure uniform density.
5. Curing and Clean-Up: While a surface skin develops within roughly 15 minutes, the adhesive cures at a rate of 2 mm per 24 hours. Clean wet tools and residue immediately with white spirits; hardened material must be removed mechanically.
