An adhesive for joining metals and resins is disclosed. The adhesive comprises 0.0001˜3 wt. % of amino silane, 0.0001˜1 wt. % of a crosslinker and 0.0001˜3 wt. % of an organometallic compound. In particular, the adhesive forms an adhesive layer that has a metal atomic ratio less than 50%.

The present invention particularly relates to synthesizing photo-initiators having poly-oligo-silsesquioxane (POSS) structure and realizing photo-polymerization by using these photo-initiators and simultaneous and in-situ synthesis of Ag nano-particles in polymer matrix comprising POSS structure and obtaining wrinkled surfaces as a result of self-arranging thereof.

The present invention relates to a crosslinking agent compound in which a terminal crosslinkable functional group is capped with a silane-based protecting group, a photosensitive composition including the same, and a photosensitive material using the same.

A polyphenylene sulfide resin composition is obtained by mixing a polyphenylene sulfide resin (a), a fluororesin (b) and an organosilane compound (c). When a resin phase-separated structure of a molded product formed from the polyphenylene sulfide resin composition is observed by an electron microscope, the component (a) forms a continuous phase, the component (b) forms a primary dispersed phase having a number-average dispersion diameter of not greater than 1 m, and a secondary dispersed phase of the component (a) is included in the primary dispersed phase of the component (b).

Provided is a hydrophobic silica aerogel precursor, and a hydrophobic silica aerogel produced using the same. In the methods, a linear silane crosslinking agent containing a PEG-derived unit is introduced when preparing a hydrophobic aerogel precursor, resulting in the production of a hydrophobic silica aerogel having improved high-temperature thermal stability and improved physical properties.

The present disclosure provides a composite structure and associated method for preparing a composite substrate comprising an inorganic coating that is adhered to an organic-based substrate via an adhesion promoting agent comprising a molecule having a urea moiety at one end of the molecule and an alkoxysilane moiety at the other end of the molecule. The use of adhesion promoting agent having at least one of an amine or imine moiety and an alkoxysilane moiety promotes tight adhesion of the inorganic coating to the substrate.

The invention relates to a curable composition, containing (A) at least one polyorganosiloxane, which has at least one hydroxy group bound to a silicon atom, (B) at least one silane of the formula (1):

Si(R.sup.1).sub.m(R.sup.2).sub.n(R.sup.3).sub.4-(m+n)(1), as defined herein, (C) at least one aminosilane, and (D) at least one tin compound,
wherein the composition is free of epoxysilane and the molar ratio of the aminosilane to the tin compound is 1:1 to 50:1, as well as to the preparation and use thereof.
