The present invention relates to a hollow glass, such as a bottle, glass, flask or pot, consisting of a glass substrate having, on at least one portion of its outer wall, a hydrophilic organic coating, for instance based on polyvinyl alcohol crosslinked with at least one acid selected from citric acid, polyacrylic acid and poly(acrylic acid-co-maleic acid). In order to manufacture this hollow glass, a solution containing the ingredients for forming the coating and at least one solvent is applied to the glass substrate by spraying, dip-coating or, when the hydrophilic organic coating is a partial coating, by spraying onto the outer wall of the glass substrate on which a mask has been applied, or by screenprinting; the glass substrate coated with said solution is dried; and the substrate is cured thermally or by UV radiation or by electron beam. It is possible to use this hollow glass for revealing a pattern thereon when said hollow glass is removed from a cold storage zone.

Hollow glass packaging object or container having an external anti-mist coating

A glazing unit includes a hydrophilic layer including a polyurethane network incorporating bis-urea functions. Furthermore, a process for manufacturing this glazing unit, includes depositing a solution containing at least one isocyanate, one polyol and one bis-urea including a polyol function, polyvinylpyrrolidone, a film-forming agent and a solvent on a glass substrate, drying the glazing unit containing the substrate and the deposited solution, and subjecting the glazing unit to a temperature of between 100 and 150&#xb0; C.

Glazing unit comprising a hydrophilic layer having an improved scratch resistance

A structure based on glass strand coated with a resin composition containing, by weight percent of solid matter: from 75 to 98% of a mixture of a first novolac having a glass transition temperature lower than or equal to 60&#xb0; C. and a second novolac having a glass transition temperature above 60&#xb0; C.; from 0.5 to 10% of a wax; from 1 to 15% selected from an imine and a modified melamine of formula (I): where R, R, R, R, R, and Rare each independently &#x2014;H, &#x2014;CHOH, &#x2014;CHOCH, or &#x2014;CHOCHOCHradical, with at least one of Rto Rnot being H; and from 0 to 10% of a plasticizing agent. Also, a resin composition for producing a reinforcing structure and bonded abrasive articles incorporating such a structure.

Glass strand structure designed to reinforce bonded abrasive articles

The invention relates to a structure based on glass fiber coated with a resin composition designed to reinforce bonded abrasive articles, the resin composition including the following constituents in the proportions indicated, expressed in percentage by weight of solid matter:

Glass fiber structure designed to reinforce bonded abrasive articles

The invention relates to a composition comprising mica and glass, said glass comprising: This composition is intended to be molded at a temperature above the Tg of the glass so as to form composite parts that can serve as an electrical insulator.

Glass for insulating composition

An aqueous polymer binder composition adapted for the manufacture of abrasive articles, such as coated abrasive articles, comprising at least one resin containing at least two azetidinium groups and at least one saccharide. The aqueous composition is formaldehyde-free and can further comprise proteins, starch grafted acrylic styrene, co-cross-linking agents, rheology modifiers, fillers, and hydrophobizing agents.

Aqueous resin composition for abrasive articles and resulting articles

An abrasive article which is made from a liquid resin composition containing no formaldehyde, which replaces the resol or urea-formaldehyde resin used as an adhesive in coated abrasives and the resol used as an impregnation resin in bonded abrasives. The liquid resin composition comprises a product that results from the oxidative cleavage of an unsaturated plant or animal oil, chosen from aldehydes, peroxides and mixtures of these compounds. The liquid resin composition can be used for the manufacture of coated and bonded abrasive articles.

Formaldehyde-free abrasive article

The invention relates to a liquid resin composition intended for manufacturing abrasives that comprises at least one novolac resin having a glass transition temperature less than or equal to 60&#xb0; C., at least one reactive diluent and optionally at least one crosslinking agent. Application of the resin composition for producing abrasive articles, especially bonded abrasives and coated abrasives. It also relates to the abrasive articles comprising abrasive grains connected by such a liquid resin composition.
