Decorative paint has to provide appealing aesthetics and increase the value in a home. At the same time, it also has to be durable enough to resist abrasion and be able to be wiped to remove dirt from food, fingers and other marks.
Dispersants play a critical role for formulations to deliver these desired properties, including vivid color strength with strong, bright colors and other aesthetic properties, such as gloss and haze. Quality dispersants prevent reagglomeration to maintain the required color quality in water-borne coatings. If there are even small agglomerates, they can affect aesthetic properties of the paints or coatings.
Because water-borne dispersants contain hydrophilic groups, they can have a negative impact on the water and stain resistance of coatings. That’s why it is important to ensure the dispersant is designed to minimize this negative impact while maintaining exceptional film properties.
Solsperse™ W430 Hyperdispersant is an excellent example in that it provides a cost-effective solution for the development of vibrant colors in durable decorative paints. Solsperse W430 provides a good balance of performance benefits—including low-VOC capabilities, stability, flow and leveling—across a range of different paint systems. It is also compatible with a wide range of binders, acrylic, epoxy, urethane and alkyd.
The benefits of Solsperse W430 are evident in the comparison below that a poorly designed dispersion can have versus a well-designed dispersion. When it comes to resistance to staining and discoloration, a dispersant can also deliver a significant level of protection. The chart compares Solsperse W430 to a commonly available paint with a standard dispersant. An advanced dispersant technology can bring additional levels of resistance to the staining effects of some common and tough household products.
