2. RTV silicone - Wikipedia

   en.wikipedia.org/wiki/RTV_silicone

   Silicones also exhibit good chemical resistance and high-temperature resistance (205 °C, 400 °F and higher). For this reason, silicone molds are suitable for casting low-melt metals and alloys (e.g. zinc, tin, pewter, and Wood's metal). RTV silicone rubbers are, however, generally expensive – especially platinum-cure.

3. 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 ...

4. Primer (paint) - Wikipedia

   en.wikipedia.org/wiki/Primer_(paint)

   Primer reduces the number of paint coats needed for good coverage and even color. A thin layer of paint may still be permeable to water. Water can permeate into the wood and cause warping, mildew, or dry rot. Primer improves the waterproofing of the finish. [4] Primers are not used as part of a wood stain treatment because they obscure the wood ...

5. Silicone rubber - Wikipedia

   en.wikipedia.org/wiki/Silicone_rubber

   In a platinum-based silicone cure system, also called an addition system (because the key reaction-building polymer is an addition reaction), a hydride- and a vinyl-functional siloxane polymer react in the presence of a platinum complex catalyst, creating an ethyl bridge between the two. [2] The reaction has no byproducts.

6. Conformal coating - Wikipedia

   en.wikipedia.org/wiki/Conformal_coating

   Film coatings ranging from 0.100 to 76 μm can be applied in a single operation. The coating thickness is uniform, even on irregular surfaces. Desired contact points, such as battery contacts or connectors, must be covered with an air-tight mask to prevent the parylene from coating the contacts. Applying parylene is a batch process that does ...

7. Flashing (weatherproofing) - Wikipedia

   en.wikipedia.org/wiki/Flashing_(weatherproofing)

   In earlier days, birch bark was occasionally used as a flashing material. [7] Most flashing materials today are metal, plastic, rubber, or impregnated paper. [8]Metal flashing materials include lead, aluminium, copper, [1] stainless steel, zinc alloy, other architectural metals or a metal with a coating such as galvanized steel, lead-coated copper, anodized aluminium, terne-coated copper ...
