Sika Industry know-how in replacing nails, screws and rivets has a long-proven track record since back in the 80’s. This journey has now begun in the modular building industry. Millions and millions of screws and nails are used by every customer: time consuming, noisy, expensive and lot of waste. In addition, producers have now requested adhesives for a bonding solution.
With a wide portfolio of products ideal for modular constructors, and a wealth of experience in many manufacturing applications, such as Automotive, Transportation, Marine, Appliances and Renewable Energy, we can help modular builders and specifiers choose the most suitable solutions for their needs.
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.
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.
Spotlight on Sikaflex®-545
Sikaflex®-545 is a very low emission one-component adhesive based on silane terminated polymer (STP) technology. It is a high initial grab adhesive with high load capacity and meets most severe environmental and safety standards with very low emissions. Sikaflex®-545 allows a powerful initial load capacity directly after application, outperforming most available silane modified products.
Sikaflex®-545 adheres well to a wide variety of substrates without the needs for special pre-treatment. It can be used on substrates such as timber, glass, metals, metal primers and paint coatings (2-part systems), ceramic materials and plastics.
Sikaflex®-545 is already used by some modular constructors, due to its well-balanced formulation with respect to the initial green strength versus efficient material output in terms of extrudability.
Compare to mechanical fixings, elastic adhesives are the ideal solution and provide the best interface between the materials as it compensates for stress coming from thermal movement. In addition, sound dampening can be improved, and corrosion is no longer an issue.
Sika has leveraged its huge product range to come up with some great solutions, to improve rigidity, reduce noise transfer, improve fire performance, reduce cycle time, lower costs, enhance sustainability, boost quality and provide a one-stop-shop from basement to roof.
