The Paint the lasts and lasts
Resin: We use an acrylic grafted with a urethane molecule. The base polymer from which the the acrylic is made is known to be the most stable of all pre-polymers. In addition we add 28% pure urethane These polymers are inherently UV resistant and remain flexible down to -40F. What you are actually installing is a "rubber" coating on your wall that flexes with the change of seasons. High temperature resistance has been checked to over 200F. Many resins are brittle and easily crack especially at lower temperatures. The also breakdown in the UV causing the classic "chalking". Our resin combination will not crack.
fillers: Most paint manufacturers use the least expensive fillers they can. Calcium carbonate is very common in paint formulations. The problem with calcium carbonate is that it is attacked by acid rain and thus is depleted from the the coating. It also serves as a food for microbial growth. Titanium dioxide is used in paints to provide a background white to reduce the amount of pigment loading.
