As the coating technology continues to evolve, industries have become more aware of the importance and benefits of waterborne polyurethane coatings. While solvent-based polyurethane is still very critical for some applications, their waterborne counterparts have emerged as more useful and popular alternatives in the past decade.
Uses
Water-based polyurethanes are primarily used in paints and coating applications. They’re generally found in textile and wood coatings. They’ve also gradually made their place in the preparation of digital inks as binders.
When the waterborne polyurethanes were first introduced, they became largely popular in the textile industry, but they’re now used in the packaging industry as well.
Notable Characteristics
- One of the key characteristics of waterborne polyurethane is that they release a considerably reduced amount of VOC. This property, combined with high performance at low temperatures, makes them highly popular in flooring applications.
- The newer waterborne polymers considerably help in reducing odor.
- Waterborne polyurethane can be used on surfaces that are sensitive to other solvents like plastics.
- Waterborne polyurethanes have lower toxin levels and are more convenient to use. They have considerably lower quantities of aromatic solvents.
- They feature a highly effective crosslinking chemistry and can be used in PUDs as well, which isn’t generally possible when using solution polymers.
- Auto-oxidative crosslinking becomes easier with waterborne polyurethanes. While you can also use it in solvent-based systems, it needs a lower solid and/ or starting molecular weight as compared to its waterborne counterparts. This helps them reach their resistance and hardness properties faster than solvent-borne materials, particularly if there’s no accelerated energy application such as applied heat. For example, this solution would be more convenient for the floor coating applications because floors generally encounter heavy use.
