Polyurethanes are used to make consumer goods like mattresses, sponges, textiles, shoe soles and many other products. Polyurethane products are made from polyols and diisocyanates.

The danger of fire is present always and everywhere. The imminent danger depends upon actual exposure, and naturally differs if the threatened construction is a pedestrian subway, a roadway tunnel or a subterranean garage in a skyscraper. Concrete is the loadbearing material in nearly all built structures and is therefore at high risk, since the entire structure would collapse upon its material failure.

Major infrastructure projects such as dams, roadways or airport runways require enormous quantities of aggregates, sought in closest proximity to construction sites. Some aggregates can exhibit an increased or high risk of ASR. Alkali-Silica-Reaction is a chemical reaction which occurs between the amorphous silica in the aggregate and the pore solution (alkalis) of the cement matrix.

Awe-inspiring gorges and valleys are nature’s testimony to the undeniable strength of water. Primarily in technical hydraulic engineering, but also in traffic zones with high loads or hard rolling bodies, concrete surfaces experience considerable and at times extremely abrasive forces. The mechanisms of damage thereby depend centrally on the type of burden.

Particularly in underground construction, concrete structures are exposed alongside loads and wear of decade-long use to influences emerging from the sub grade such as permanent mechanical stresses and aggressive water.

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.

Polyurethane adhesives are the standard for vehicle glass bonding. Since the windshield fulfills more functions than just keeping the rain out, specifications from car producers are best met by polyurethanes.

Smart use of water–based materials can be an effective strategy against moisture-related problems in floor constructions. This is what we implement in our Sikafloor® MultiDur water-based epoxy range. Tough and water vapor permeable, plus low VOC & odor, Sikafloor® MultiDur water-based epoxy flooring systems are especially suitable for your next functional floors if you have issues of humidity or rising moisture in the floor slab. Additionally, among the range, the system Sikafloor® MultiDur WS-26 has the unique performance of the fire classification A2fl -S1.
