polysulfide sealants market boosted by infrastructure development

Boost in demand for 2K polysulfide sealants market

In 2018, the worth of the global polysulfide sealants market was over a billion dollars, and the market is still growing at a significant rate. In the period 2019-2029, sizable opportunities are expected, especially regarding 2 component polysulfide sealants which account for more than 70% of the consumption of global polysulfide sealants.

Polysulfide sealants for civil engineering & infrastructure grow fastest

The fastest growing segment of 2K polysulfide sealants is forecast to be civil engineering and infrastructure as well as commercial applications. These are expected to account for three quarters of the total volume. The applications include bridges, roads and tunnels as well as airports, ports, landfill construction and parking garages.

East Asia and mature markets dominate the growth

Geographically seen, the most growth in polysulfide sealants is likely to take place in East Asia which reportedly is a top-consuming market. Other geographical markets where the consumption of polysulfide sealants is expected to be high are the more mature ones: North America and Europe which together are projected to generate $200 million over the forecast period. Additionally, fast paced construction activities and developments in infrastructure in emerging markets such as China and India are likely to boost the demand for and growth of polysulfide sealants.

concrete sealant needed for a crack

New sealant for repairing concrete when the time is limited

Concrete surfaces are durable, but may occasionally suffer from splits, cracks and spalls affecting the safety and appearance of the surface. A new fast-drying sealant has been developed to quickly repair that kind of damage on concrete surfaces. The same product can also be used for securing threading and anchoring in concrete surfaces.

3M concrete sealant cures fast and can be painted

The concrete sealant is primarily suitable for use by contractors, but allows also for DIY projects. Developed by 3M, the flexible sealant expands while curing, and will neither shrink nor crack when applied to any depth. The sealant is self-leveling when slightly overfilled, and it cures in 5 minutes, can be sanded after 15 minutes after application and allows for painting within an hour.

3M reports that the concrete sealant is solvent-free and suitable for use in construction, shop floors, stairways and walkways. The product can be applied with a common caulking gun, which makes it accessible also for DIY projects.

proper storage of epoxy adhesives leadingg to efficient product

Proper Storage of epoxy adhesives for efficiency

Epoxy adhesives are widely used throughout industries due to their many benefits. To ensure that the adhesives retain the benefits and their functionality, it is crucial to consider the product-specific storage requirements of each system.

Storage of one and two component epoxy adhesives

When storing one and two component epoxies, the product-specific requirements must be taken into account. However, for all epoxies, the storage area must be well-ventilated. Ideal storage temperature, in turn, varies per product. For example one part epoxies are usually stored between between 5°C and 10°C (40°F and 50°F), and they must be brought to ambient temperature prior to application. 2K epoxy adhesives, for their part, are generally stored in drier areas and higher temperatures, usually between 20°C – 25°C (68°F – 77°F).

An exception is premixed 2K epoxy which must be stored frozen, in -40°C (-40°F), to let it retain its functionality for 6 months. The premixed epoxy is melted prior to application and can neither be refrozen nor reused, as it cures in room temperature.

Other factors to consider with epoxy glues

To further improve the efficiency of epoxy based adhesives, it is important to be aware of the date of manufacture, and ensure product containers are closed properly with the correct lids. Also machinery and equipment should be thoroughly cleaned between products to avoid cross-contamination. Additional attention is required when storing flammable and hazardous materials.
