2. Silicone resin - Wikipedia

   en.wikipedia.org/wiki/Silicone_resin

   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 −).

3. Siloxane - Wikipedia

   en.wikipedia.org/wiki/Siloxane

   The main route to siloxane functional group is by hydrolysis of silicon chlorides: 2 R 3 Si−Cl + H 2 O → R 3 Si−O−SiR 3 + 2 HCl. The reaction proceeds via the initial formation of silanols (R 3 Si−OH): R 3 Si−Cl + H 2 O → R 3 Si−OH + HCl. The siloxane bond can then form via a silanol + silanol pathway or a silanol + chlorosilane ...

4. Silyl modified polymers - Wikipedia

   en.wikipedia.org/wiki/Silyl_modified_polymers

   Sealant products manufactured with silyl-modified polymers generally have most of the desirable properties of acrylic- or polyurethane-based products, including high opacity, short drying time, and good paint adhesion, as well as some key properties of silicone-based products, including adhesion to a wider range of substrate materials, higher ...

5. Silicone - Wikipedia

   en.wikipedia.org/wiki/Silicone

   Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...

6. Roof coating - Wikipedia

   en.wikipedia.org/wiki/Roof_coating

   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.

7. Nail (fastener) - Wikipedia

   en.wikipedia.org/wiki/Nail_(fastener)

   Once the casing has been removed, the nails can be extracted from the inner frame with any of the usual nail pullers; Clout nail – a roofing nail; Coil nail – nails designed for use in a pneumatic nail gun assembled in coils; Common nail – smooth shank, wire nail with a heavy, flat head. The typical nail for framing
