Silicone vs Acrylic

One of the primary reasons to believe silicone is a superior product is that it only requires one coat to be applied to most roofs. Silicone coatings have the highest solids content on the market. We can apply 40+ mils in a single coat, which is more than enough to protect your roof. Silicone also requires less reinforcement than other spray-applied coatings. Because it is so elastic, it can conform to many different shapes, as well as hold strong on the roof when temperature swings cause the roof to expand and contract.

Safe for the Environment

VOC’s, or Volatile Organic Compounds are often found in spray-applied roofing coatings, and they can be damaging to human health and the environment in which they are sprayed. One of the biggest advantages of silicone in the silicone vs acrylic battle is that silicone roof coatings are extremely low VOC. Our coatings have a VOC content so low that they are approved to be sprayed anywhere based on VOC content, meaning they meet even the most stringent requirements. Our low VOC content keeps workers safe while they install the coating, and it means the material is safe for the surrounding environment. When it comes to VOC’s, there is a clear winner in the silicone vs acrylic argument.

Superior UV Stability and Performance

Silicone can maintain adhesion and performance under ponding water. The ability to resist ponding water of silicone vs acrylic coatings is not even close. A water-based acrylic system cannot withstand ponding water, because as you may have guessed, acrylic is water based. Another benefit of the silicone is that it doesn’t chalk, degrade, or haze from UV exposure thanks to its strong chemical makeup.

Conclusion

Silicone is far superior to acrylic in many ways as showcased above. As stated, silicone is not the right choice in every situation, and acrylic will occasionally be a better fit, but on the whole, silicone is a superior system for many different reasons.
