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 present invention relates to a thermally curable liquid resin composition capable of being used in the manufacture of abrasive articles, and to the resulting abrasive articles.

Liquid resin composition for abrasive articles

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.

A resorcinol-modified phenolic resin composition is formed by reacting a basic catalyst, formaldehyde, water and a benzene-ol to form an intermediate composition to which resorcinol is subsequently added to reduce the presence of free formaldehyde. Optionally, an alkanolamine can be combined and reacted with the resorcinol-modified phenolic resin composition to form a resorcinol-alkanolamine-modified phenolic resin composition. The resorcinol-modified phenolic resin and the resorcinol-alkanolamine-modified phenolic resin compositions can be employed to coat abrasive products having a relatively low free formaldehyde content.

Phenolic resin formulation and coatings for abrasive products

The invention relates to a sizing composition intended to be applied to mineral fibers, especially glass or rock fibers, which contains at least one polycarboxylic acid and at least one polyamine. It also relates to a method of preparing the composition, to its use for sizing mineral fibers for the purpose of forming, in particular, thermal and/or acoustic insulation products, and to the products obtained.

Mineral fibre sizing composition containing a carboxylic polyacid and a polyamine, preparation method thereof and resulting products

The invention relates to a sizing composition for a thermal and/or acoustic insulation product, based on mineral wool, comprising an epoxy resin of the glycidyl ether type, an amine hardener and an accelerator chosen from imidazoles, imidazolines and mixtures thereof. Application to the manufacture of thermal and/or acoustic insulation products having improved mechanical properties after aging, especially in a wet environment.

Sizing composition for an insulating product based on mineral wool, and resulting products

The invention relates to a thermal and/or acoustic insulation product based on mineral fibers for use above 150&#xb0; C., especially between 200 and 500&#xb0; C., or even up to 700&#xb0; C. and higher in the case of rock fibers, which comprises at least 1%, or at least 2% and even more than 4% by weight of binder obtained from a sizing composition, the resin or resin mixture of which consists substantially of at least one epoxy-type resin whose EEW value is between 150 and 2000, preferably at least 160 and/or at most 700, or even at least 170 and/or at most 300.

Insulation product, such as a thermal insulation product, and production method thereof

Insulating product based on mineral wool sized with a binder based on a phenol-formaldehyde resin, in which the binder comprises, as a mixture: Use of such a sizing composition for manufacturing insulating products, while reducing the emissions of ammonia gas on the manufacturing line.

Insulation product in particular thermal containing a binder based on phenol-formaldehyde resin and method for making same

A phenol-formaldehyde resole resin is prepared using a high level of catalyst at a polymerization temperature of about 63&deg; C. The endpoint, measured by salt water tolerance, is selected so that the resulting resin has a water dilutability of 20:1 at neutral pH after storage for three weeks at a temperature of about 13&deg; C., with a free phenol level of no more than 0.50 percent.

Low emission formaldehyde resin and binder for mineral fiber insulation

A sizing composition which is a phenol-formaldehyde resin substantially free of urea or of a urea derivative and which has reduced emissions of isocyanates upon heating. Insulation products based on mineral wool, especially glass wool or rock wool, which are suitable for mass-produced thermal appliances and contain the sizing composition have reduced organic emissions during manufacturing and when used in thermal appliances.

Insulation product, especially thermal insulation product, and its manufacturing process

The invention relates to a resin composition based on a urea-modified phenol-formaldehyde resole which has a formaldehyde/phenol molar ratio of 2 to 5, exhibiting a free formaldehyde content lower than or equal to 3 percent (by weight relative to the total weight of the composition), a free phenol content lower than or equal to 0.5 percent and a dilutability measured at 20&deg; C., of at least 1000 percent and to a process for the preparation of this composition. This composition is characterized in that it contains an overcondensed resole obtained by the condensation of phenol, of formaldehyde, and optionally of urea in basic medium, until the product has a water dilutability at pH 9 that is lower than or equal to 2000 percent, or the product of neutralization of such as resole. The modification of an overcondensed phenolic resole by neutralization with boric acid according to the invention permits the dilutability of the resole to be increased. An application is for sizing composition s for products based on mineral wool with a reduction in atmospheric pollution upon use.
