Abstract:
The present invention relates to a method of preparing moisture-curable silylated polymers by reacting amino- or carboxy-containing polymers with methylenehydrocarbyloxysilanes, and to the compositions formed thereby. In particular, the inventive compositions possess fast moisture-curable capabilities. Illustrative of the compositions of the present invention are those including a polymer of Formula (I).
Abstract:
The invention relates to the discovery that pre-treating mineral oxide particles with a silylated polymeric coupling agent prior to suspending the particles in a binder polymer increases the crack resistance and adhesion of particles to a inkjet printing substrate such as paper sheets. Such pretreatment also reduces the amount of binder needed to achieve acceptable performance, leading to improvements in production speed and image quality.
Abstract:
The invention relates to a polymer dispersion containing water and at least 60 wt. % of an organic polymer which has at least one group of general formula (I) A-Si(Z)n(OH)3-n. The invention also relates to a composition containing at least one organic polymer which has at least one group of general formula (I), and at least one other organic polymer or a mixture of two or more other organic polymers.
Abstract:
A radiation-curable composition for use as an optical fiber material or coating comprising the combination of the following pre-mixture ingredients: (A) about 5 wt.% to about 95 wt.& of one or more radiation-curable oligomers, (B) about 5 wt.% to about 95 wt.% of one or more monomer diluents, (C) optionally, one or more photoinitiators, (D) about 0.1 wt.% to about 30 wt.% of one or more adhesion promoters represented by: R -L-Si(OR )3 wherein R is a group comprising an ethylenically unsaturated radiation-curable group; and said three R groups independently of each other are C1-C10 groups; and L is a linking group which comprises one or more alkoxy or branched propoxy groups.
Abstract:
A sprayable coating composition that contains at least one soluble film-forming silicon-containing compound having, on average, more than one functionalized silicon group, a volatile organic carrier, a polymer microparticle component, and a catalyst; a substrate coated with the composition; a process for coating the substrate to provide a protective finish; the finish-protected substrate; certain oligomeric compounds and a process therefor.
Abstract:
A composition comprising water and the following components: (a) an epoxy compound comprising at least one epoxy group and at least one hydrolysable silyl group; and (b) a hydroxy functional polymer having carboxy and/or sulpho groups. The compositions are generally water-based and may be used for making films and coatings having good mechanical and physical properties.
Abstract:
A thermosetting composition comprising a hydroxylated resin, a hydrolyzable silyl compound polymer, a hydrolyzable silicon compound, and a curing catalyst gives a coating material free from the problem of malodor, and a coating film prepared therefrom is improved in adhesion, solvent resistance and hardness.
Abstract:
The present invention is directed to a coating composition, such as a substantially clear coating composition, which comprises (1) an alkoxysilane, (2) a polysiloxane, (3) a plurality of particles, and (4) curing agent that is reactive with the polysiloxane. The coating composition of the present invention can exhibit increased physical properties, such as scratch resistance, when compared to similar coating compositions that lack the components disclosed herein.
