When compared with silicone rubber epdm is significantly inferior with a maximum temperature of 130 c 266 f. Caulking is a common term that mainly refers to sealing cracks or any kind of penetrations in order to prevent water leakages. After all the roofs we ve installed coating on epdm is the only one that we ve found to require a primer. Unfortunately silicone roof coatings are also the victim of many far fetched myths and common misconceptions we need to address.

In compression set neoprene is right there with epdm though neither match silicone in that area.

It can actually withstand slightly higher heat than epdm which makes it ideal for engineering and automotive locations. Many silicone roof coatings do provide excellent value for commercial roofs. That s it that s the list. Nbr is also more resistant to water swell and weathering elements.

On the other hand both silicone and epdm stand up to higher temperatures with silicone topping epdm. When it comes to your requirements both have a place in the market for industry uses. Therefore it s essential you make an informed decision based on price strength properties and so on.
