Abstract:
A polymer composition containing a specific silyl group-containing polymer, in which the maximum size of particles contained therein is 2 µm or less, and the number of particles having a size of 0.2 µm to 2 µm is 1,000 particles/ml or less. The composition may further contain a specific compound or at least one component selected from an organosilane represented by (R 1 ) n Si(X) 4-n , a hydrolyzate of the organosilane and a condensate of the organosilane. The composition is excellent in storage stability, high in hardness and excellent in mechanical strength such as wear resistance, so that a coating film having good taking-up properties even when no lubricant is contained, extremely smooth and having no difference in film thickness can be formed.
Abstract:
Ambient temperature curing coating composition comprising a polysiloxane having the formula (I): wherein each R1 is selected from the group consisting of alkyl, aryl, and alkoxy groups having up to six carbon atoms, reactive glycidoxy groups, and OSi(OR3)3 groups, wherein each R3 independently has the same meaning as R1, each R2 is selected from the group consisting of hydrogen and alkyl and aryl groups having up to six carbon atoms, and wherein n is selected so that the molecular weight of the polysiloxanes is in the range of from 500 to about 2,000, and alkoxysilyl-functional acrylic polymer, and a curing catalyst. The invention further relates to the preparation of an alkoxysilyl-functional acrylic.
Abstract:
A film-forming composition, typically a topcoat, having improved adhesion to certain commercially available adhesives. The composition includes a curable film-forming polymer, typically an acrylic and/or a polyester polymer, with carbamate and/or urea groups. The composition further includes a material containing one or more hydrolyzable silyl groups. The hydrolyzable silyl group-containing material optionally can be a polymeric or oligomeric. Also disclosed are a method of applying the above described film-forming composition to a substrate and the coated article prepared by such a method.
Abstract:
A coating fluid for forming a coating on a support for use in inkjet printing comprises a liquid medium having dispersed therein (a) an inorganic oxide selected from aluminium oxide and silica, (b) a binder polymer, and (c) a polymeric crosslinking agent containing functional groups for reaction with the inorganic oxide. The components (a), (b) and (c) are preferably dispersed in an aqueous liquid and the relative amounts of inorganic oxide to polymeric crosslinking agent are from 500: 1 to 15:1 preferably 250:1 to 20:1, the relative amounts of inorganic oxide to binder polymer are from 50:1 to 2:1 preferably 20:1 to 4:1 and the relative amounts of binder polymer to polymeric crosslinking agent are from 40:1 to 2:1 preferably from 20:1 to 3:1 the amounts being by weight on a dry basis.
