North Central Insulation coatings are elastomeric, meaning they are able to stretch as the substrate warms and cools through the day and through the seasons. North Central Insulation mainly uses Acrylic, Silicone or Polyurea Elastomeric coatings in our roofing and other applications:
Acrylic coatings can be applied through spraying or brushing with minimal to no odor release. Acrylics dry to the touch in 60 minutes or less and typically cure completely in 24 hours. During cure, acrylics do not shrink and give off little to no heat, it is fungus resistant, provides longer than average pot life, and has good moisture protection.
Silicone coatings are most recognized for their stability over a wide temperature range and during temperature cycling. The coating is very effective for repairing weathering, withstand heavy ponding water, fast curing time and they do not chalk off over time because they are not water based they don’t absorb any moisture.
A polyurea-based coating is made up of two components that are an isocyanate compound and a resin blend. These coatings fully cure in a few hours to form an outstandingly tough, flexible and a chemical resistant surface. These coatings waterproof their substrate and also have the ability to extend by about 300 percent. Elastomeric polyureas are ideal for application on industrial work floors, hangars, parking decks, roofs and so on and are great for corrosion protection and abrasion resistance. Although a fairly new coating, the markets and applications are endless and rapidly on the rise.
Additional polyurea advantages and benefits include: Weather tolerant for curing, excellent resistance to thermal shock, flexible - elastomeric, waterproof, seamless, resistant to various solvents and have shown resilient excellent bond strengths to properly prepared substrates.
With a decent recoating schedule - it's best to recoat when pinholes first appear - a foam roof can last for decades. Dick Fricklas
