Bison Poly Max Crystal

PRODUCT DESCRIPTION
Universal, crystal clear construction adhesive and sealant based on unique SM Polymer technology. For bonding, fixing and sealing at the same time. Suitable for practically all (building) materials and all surfaces (even and uneven, porous and non-porous). Crystal clear, extra strong and permanently elastic. Replaces construction adhesive, wood adhesive, wood construction adhesive, PU-adhesive, silicone and acrylic sealant.

FIELD OF APPLICATION
Bonding: e.g. glass, stone, natural stone, concrete, plasterwork, many plastics, wood, chipboard, trespa, iron, aluminium, zinc, steel, stainless steel and other metals, ceramic tiles, cork mirrors.
Fixing: e.g. skirting boards, laths, timber framework, window sills, doorsteps, roof fascias, panelling and insulation material, gypsum boards, polystyrene ornaments and decorative edgings.
Sealing: Applications in construction: connecting joints in (plastic) window frames, roof fascias, roofs, roof gutters, walls, skylights and chimneys. Sealing joints between window panes and frames. Not suitable for polyethylene (PE), polypropylene (PP), PTFE, PA (nylon), acrylic glass (plexiglass) and bitumen.

PREPARATION
Working conditions: Use only temperatures between +5°C and +40°C.
Preliminary treatment: Surface must be clean and free of dust and grease. Use of primer not required. Surfaces may be slightly moist. Surface must be solid.
Tools: Use sealant gun

APPLICATION
Coverage
Spot bonding: Approx 5-8 m²/kg
Line bonding: 8-15 m for 1 cartridge (depending on diameter of cut off nozzle)

Directions for use
Bonding and fixing: Cut off nozzle to a diameter of at least 0.5cm.
Sealing: Cut off nozzle slantwise at required joint width.
Bonding and fixing: Apply adhesive evenly in vertical strips or dots (every 10-40cm). Always apply adhesive at corners and along edges of board material. Attach materials within10 minutes and press firmly or tap lightly with a rubber mallet. If necessary, secure or support heavy materials for 24 hours.
Sealing: Inject adhesive sealant evenly into joint and tool within 10 minutes with a moist putty knife, sealant smoother of finger (preferably wetted with soap water without lemon). Tool vertical joints from bottom to top. Surface skin after approx 15 minutes. Complete cure after a few days (depending on layer thickness).
Stains/residue: Immediately remove wet stains with turpentine. Dried adhesive residue can only be removed mechanically.

CURE TIMES
Skin over time: Approx 35 minutes
Cure rate: 2mm/24 hrs
Full bond strength: Full bond strength after approx 24 hours

*Curing time may vary depending on the surface, product quantity used, humidity level and ambient temperature.
