The mechanical stability, freeze-thaw stability and shelf-life of paints are all improved by the addition of surfactants. The addition of surfactants to paint also allow the paint to coat a surface more easily because surfactants increase the wetting of a solution. [4]
Freeze thaw resistance, or freezing and thawing resistance, is the property of solids to resist cyclic freezing and melting. See also. Frost weathering;
The Dutch painting forger Han van Meegeren mixed phenol formaldehyde with his oil paints before baking the finished canvas, in order to fake the drying out of the paint over the centuries. [citation needed] Atmospheric re-entry spacecraft use phenol formaldehyde resin as a key component in ablative heat shields (e.g. AVCOAT on the Apollo modules).
The throwpower of a coating is dependent on a number of variables, but generally, it can be stated that the higher the coating voltage, the further a given coating will "throw" into recesses. High throwpower electrophoretic paints typically use application voltages in excess of 300 volts DC.
The traditional explanation for frost weathering was volumetric expansion of freezing water. When water freezes to ice, its volume increases by nine percent.Under specific circumstances, this expansion is able to displace or fracture rock.
Acrylic resin is a common ingredient in latex paint (UK: "emulsion paint"). Latex paints with a greater proportion of acrylic resin offer better stain protection, greater water resistance, better adhesion, greater resistance to cracking and blistering, and resistance to alkali cleaners compared to those with vinyl.

According to EN 13523-0, a prepainted metal (or coil coated metal) is a ‘metal on which a coating material (e.g. paint, film…) has been applied by coil coating’.When applied onto the metallic substrate, the coating material (in liquid, in paste or powder form) forms a film possessing protective, decorative and/or other specific properties.
Architectural coatings [1] [2] or paints [3] are paints and other coatings used to paint the exteriors and interiors of buildings, often called or external masonry coatings. Clear varnishes and lacquers are generally excluded. [1] Such products are usually designated for specific purposes such as roof coatings, wall paints, or deck finishes. [2]
