Steel Towers - an Economic and Proven Overall Solution
Owners,engineers and contractors need a range of products for fast, efficient and durable erection of steel, concrete or hybrid towers.
Most large wind turbines are equipped with tubular steel towers which must be able to perform in some of the harshest working environments in the world over long periods of time. Due to their exposed locations they are subjected to a multitude of stresses.
Sika has therefore formulated corrosion protection coating systems for steel tower sections, which cover the full range of defined corrosive categories that protect both the interior and exterior of onshore steel towers.
Corrosion Protection
SikaCor® and Sika® Permacor® high quality corrosion protection systems for - interior and - exterior surfaces of steel towers are based on high-strength, modern binder resins which enable very low solvent content formulations.
Primers with active pigments and thick-layer intermediate coatings ensure long-lasting corrosion protection, the top coats based on polyurethane technology meet the highest requirements for weather resistance and colour stability. In several decades of service, our corrosion protection systems have protected over 10,000 wind turbines.
Sealing & Bonding between Joints
Sikaflex® and SikaHyflex® stand for best-in-class and high quality envelope sealants. To achieve best performance for your application our assortment comprises of all major sealant technologies. Advanced polyurethane sealants for porous substrates and innovative silicones for non-porous substrates, or where a high adhesion is required, our unique silane-modified polymer range. Element bonding adhesives provide a rigid bond between elements to transfer load. Sikadur® epoxy adhesives have been used effectively to bond precast concrete elements together and provide a waterproof seal. They also have excellent adhesion to many other materials and can be used to bond different substrates.
Grouting to fill Voids
Sika grouting technologies are cementitious, resin or polyurethane binders. Engineering grouts are designed to completely fill voids and transfer load. SikaGrout® and Sikadur® are ideal for the filling of - vertical or horizontal joints; - for levelling of interacting concrete surfaces and filling very small holes - Sika cable grouts fill small crevices around post tensioned wires to protect the steel from corrosion.
