Sikaflex-545 is said to adhere well to a wide variety of substrates without the need for special pre-treatments. It can be used on substrates such as timber, glass, metals, metal primers and paint coatings (two-part systems), ceramic materials and plastics.
A big advantage of bonding over traditional mechanical fixings with screws or nails is the larger fixing area, which consequently offers a far more homogeneous and uniform distribution of any stress caused in manufacture, movement to site, or in life service. Sika can advise whether the substrates to be joined are suitable for a bonded solution.
The use of construction adhesives for structural and non-structural bonding on construction sites is gaining more importance due to new materials, new methods of building and increasing time pressure.Examples range from the simple bonding of wooden laths, plaster or insulation boards, to the bonding of facade elements and structural reinforcement.
Compared to mechanical fixing, elastic adhesives compensate for stress coming from thermal movement. In addition, sound dampening can be improved, and corrosion is no longer an issue, according to Sika.
