What are the main differences between Epoxy and Urethane?
Urethane topcoats are available in gloss or satin sheens. These coatings provide exceptional abrasion resistance, UV resistance, and flexibility. Epoxy topcoats can be applied at high mil thicknesses, are lower VOC, and may be more budget friendly. The choice between epoxy and urethane will depend on the client’s budget and performance expectations. Both type of coatings offer clear and pigmented product selections.
How do I add Chemical Resistance to my system?
Some environments may be exposed to harsh chemicals or cleaning agents. Most urethane topcoats will provide excellent chemical resistance for typical chemical exposures. In areas that have harsher chemical exposures, a novolac epoxy topcoat may be necessary. Novolac epoxy systems provide mid-range to high performance chemical resistance.
Which coatings are best for low odor considerations?
Some urethane topcoats have stronger solvent odors than others. Areas such as retail applications, residential areas, or manufacturing areas that haven’t closed completely for production may require a lower odor topcoat. Water-based and polyaspartic urethanes offer lower odor selections than solvent-based aliphatic polyurethane topcoats.
Which Coatings are best for VOC Compliance?
VOC regulations vary from region to region. In some areas, topcoat choices may be more restricted due to stricter VOC regulations. For those areas, you will want to choose a lower VOC product. High solid urethanes typically meet VOC regulations, even in the areas that have more strict regulations, such as CA. Epoxy topcoats could also be considered, depending on the system and environment.
Which coatings are best for the fastest return to service?
When a quick cure product is necessary, polyaspartic urethanes are your best choice. Polyaspartic urethanes offer quick cure times, with some available for light foot traffic in 1-2 hours.
Which topcoat should I choose?
For decorative epoxy floor systems, such as paint chips, quartz, and metallic, a clear epoxy or urethane topcoat should be used. Pigmented urethane topcoats should be used for solid color systems. Epoxy coatings are not as UV stable as urethanes, so using a pigmented urethane topcoat will help protect the color stability of the floor. Clear urethane topcoats will not offer as much UV protection for solid color systems.
Can I add slip resistance to my system?
When a more slip resistant surface is desired, aggregates or powders can be added to the topcoats to provide a more textured surface. High wear additive powders can be added to thin mil topcoats. For more aggressive textures and for thicker mil coatings, an aluminum oxide aggregate or broadcast sand should be used.
