  2. Sealant - Wikipedia

    en.wikipedia.org/wiki/Sealant

    Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal. In building construction sealant is sometimes synonymous with caulk (especially if acrylic latex or polyurethane based) [2] and also serve the purposes of blocking dust, sound and heat transmission. Sealants may be weak or ...

  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. 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 rubber - Wikipedia

    en.wikipedia.org/wiki/Silicone_rubber

    Silicone rubber is an elastomer (rubber-like material) composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations.

  6. Butyl rubber - Wikipedia

    en.wikipedia.org/wiki/Butyl_rubber

    Polyisobutylene and butyl rubber are used in the manufacture of adhesives, agricultural chemicals, fiber optic compounds, ball bladders, O-rings, caulks and sealants, cling film, electrical fluids, lubricants (2 stroke engine oil), paper and pulp, personal care products, pigment concentrates, for rubber and polymer modification, for protecting ...

  7. Silicone grease - Wikipedia

    en.wikipedia.org/wiki/Silicone_grease

    Silicone grease is widely used as a temporary sealant and a lubricant for interconnecting ground glass joints, as is typically used in laboratory glassware.Although silicones are normally assumed to be chemically inert, several historically significant compounds have resulted from unintended reactions with silicones.

  8. RTV silicone - Wikipedia

    en.wikipedia.org/wiki/RTV_silicone

    RTV silicone (room-temperature-vulcanizing silicone) is a type of silicone rubber that cures at room temperature. It is available as a one-component product, or mixed from two components (a base and curative).

  9. Polydimethylsiloxane - Wikipedia

    en.wikipedia.org/wiki/Polydimethylsiloxane

    The polymer is manufactured in multiple viscosities, from a thin pourable liquid (when n is very low), to a thick rubbery semi-solid (when n is very high). PDMS molecules have quite flexible polymer backbones (or chains) due to their siloxane linkages, which are analogous to the ether linkages used to impart rubberiness to polyurethanes .
