With high humidity levels such as in Central America, moisture cured polyurethane is essential in industrial sectors where the protection and durability of infrastructure in aggressive environments is essential. In this context, Wasser Coatings offers advanced solutions to address these conditions, as Ben Forde, Head of Business Development at the company, explained during his interview.
Moisture cured polyurethane is an industrial coating formulated to harden on contact with ambient humidity, using ambient water vapor as a catalyst to initiate a chemical reaction that forms a protective film over concrete or metal surfaces. Its main advantage is that it allows applications even in extreme conditions of up to 99% relative humidity, where other coatings would fail.
Thanks to their formulation, these coatings offer high corrosion resistance, excellent adhesion and flexibility to protect infrastructures in sectors such as oil and gas, bridges or industrial facilities, ideal for tropical environments and coastal areas where humidity is always present.
Wasser presented, during the LatinCORR 2025 event, its industrial coatings based on moisture cured polyurethane, which incorporate micaceous iron oxide in their formulas, which reinforces flexibility and allows the coating to adapt to corners and angles, reducing the usual failure points in traditional coatings. Ben Forde, commented that among the most relevant projects in which they have used this technology are:
In the case of piping, they offer two alternative systems, a polyurea coating with thicknesses from 15 to 80 mils, and a thin film system composed of three layers that allows for ranges from 11 to 19 mils, depending on customer needs and environmental conditions.
Another strength of Wasser Coatings products is their environmental commitment, with strict compliance with volatile organic compound (VOC) standards, remaining below 100 grams per liter, making them a sustainable and safe option for both the environment and operators. This ensures their use in Latin and Central American countries without regulatory difficulties.
The company adopts a consultative and technical approach in assessing each client's needs, where the first step is to understand the client's expectations and based on this, the company performs detailed inspections and recommends the appropriate level of surface preparation. For long-term solutions, complete removal of previous coatings (SP10 preparation) is often suggested, while for medium-term solutions, they propose over-coating systems that require less preparation, reducing costs without sacrificing performance.
Wasser Coatings, with its technical team, demonstrates that it is possible to combine adaptability and sustainability in solutions designed to prolong the useful life of critical infrastructure in environments where humidity is highly prevalent, such as Central America. Together with successful cases such as the Bridge of the Americas and the Golden Gate Bridge, the company reinforces its position as a key partner in industrial and infrastructure sectors.
