This means a roof coating actually becomes the top layer of a composite roof membrane and underlying system. As such, the roof coating is the topmost layer of protection for the membrane, receiving the impact of sunlight (both infrared and ultraviolet (UV)), rain, hail and physical damage. Roof Coatings should not be confused with deck coatings.
A shingle is the generic term for an individual roofing unit that is applied with other such units in an overlapping fashion. [3] Wood shingle, shingles sawn from bolts of wood such as red cedar which has a useful performance life expectancy of up to 30 years. However, young growth red cedar has a short life expectancy and high cost.
In rural Scandinavia, wood shingles were a common roofing material until the 1950s. [disputed – discuss] Wood shingles are susceptible to fire and cost more than other types of shingle so they are not as common today as in the past. Distinctive shingle patterns exist in various regions created by the size, shape, and application method.
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]
Silicone resin with R = CH 3, H or OH. Silicone resins are a type of silicone material which is formed by branched, cage-like oligosiloxanes with the general formula of R n SiX m O y, where R is a non-reactive substituent, usually methyl (Me = −CH 3) or phenyl (Ph = −C 6 H 5), and X is a functional group: hydrogen (−H), hydroxyl (−OH), chlorine (−Cl) or alkoxy (−O −).
Moisture cured polyurethane–urea coatings have been made by reacting 1,2,3-triazole rich polyether polyols with HMDI at NCO/OH eq. ratio of 1.2 to obtain isocyanate-terminated polyurethane prepolymers. The prepolymers were cured under atmospheric moisture to make polyurethane–urea free films. [5]
