For elastic bonding of mirrors on ceramics, glass, plastic, stainless steel, aluminium, wood, concrete, plaster, masonry, gypsum board, aerated concrete or untreated wood. Commercially available mirror coatings do not need to be primed. OTTO Primer 1105 must be applied thickly on mineral surfaces. Airing-out takes at least 30 minutes.
Coated chipboard must be pretreated with OTTO Primer 1216. When bonding onto substrates not mentioned here, please consult our Applications Technology department.
Never apply S 16 in dots or over the whole surface but always in vertical stripes (beads). At least three adhesive stripes of approx. 10 mm width each have to be applied per square metre of mirror in order to facilitate the air circulation required for vulcanisation. The minimum distance between mirror and substrate must stringently be 1.6 mm, which can be realised by sticking on spacers. Preliminary fixation until curing (at least 48 hours) can be carried out with adhesive strips, blocks of wood or wedges. For sealing the outside edges of the mirror in combination with natural stones we advise S 70, in combination with other materials like ceramics, metal, glass etc. we advise
S 120, S 121 and S 125.
Please note that sealing of the outside edges of the mirror must not take place before complete curing S 16 and the decomposition products have completely escaped. This takes about 7 days. Mirrors without glass backs should only be sealed at the vertical edges to avoid damages to the mirror coating due to the formation of condensed water.
