Details

Mirror is a neutral-curing, high-viscosity silicone adhesive specifically formulated for the professional bonding of mirrors and lacquered glass to various types of substrates. Its exceptional durability and perfect adhesion to the substrate make it the ideal product for this delicate application. Mirror does not attack paintwork, thus avoiding the inconvenience of oxidation with consequent loss of mirror reflection and the unsightly appearance of dark spots.

Instructions for use

  1. Clean, degrease and dry the surfaces to be bonded. Do not bond to surfaces that are not solid or that may cause plasticisers or oils to migrate.
  2. Insert the cartridge into the appropriate gun, open it, screw on the nozzle and cut the tip to obtain a sufficient opening (5 mm).
  3. Apply in vertical and parallel beads, spaced 15-20 cm apart on average; after pressing, the adhesive strips must have a maximum width of 1 cm. For optimal bonding, apply at least 10 cm of sealant bead for every kg of mirror weight (10 cm² of bonding surface per 1 kg of weight). For better air circulation, interrupt the beads longitudinally every 20 cm.
  4. Alternate Mirror cordons with double-sided adhesive tape to give thickness to the glue and immediate support, at least until the adhesive has completely polymerised.
  5. Bond before the adhesive forms a surface film. Lay the mirror, pressing it down gently to ensure a ventilation gap of approximately 2 mm, which is necessary for the cross-linking of the adhesive cordons. It is advisable to use special spacers.
  6. Normal ambient humidity must be ensured during hardening. After approximately 72 hours (at 20 °C and 50% R.H.), the sealant is sufficiently hardened; until then, maintain the mechanical fastening.

Storage

Mirror must be stored in a dry, cool environment. Under these conditions, it will remain stable for at least 12 months. Cartridges that have not been completely used up can be stored for approximately 3 months if tightly closed.

Warnings

As this is a particularly challenging and delicate bonding operation, it is essential to follow the instructions carefully. Otherwise, Torggler srl will not be liable for any anomalies. When bonding mirrors with safety film covering 100% of the surface, first apply Sitol Primer Deck Caulking.

Bonding of mirrors and lacquered glass to typical building and furnishing substrates: plywood panels, plasterboard, plaster, concrete, natural or treated wood, glass, aluminium, sheet metal, steel, etc. The flexibility of the adhesive layer, resulting from Mirror’s high elastic modulus, guarantees long-term adhesion by compensating for small movements caused by vibrations, settling and differential thermal expansion of the mirror/support system.
