A method of preparing a low bubbling and low yellowing, high refractive index polyurethane or polythiourethane is provided. A method of evaluating an aromatic polyiso(thio)cyanate material, such as an aromatic diisocyanate, e.g., m-xylylene cyanate, is provided. The method evaluates transmittance in a sample of the isocyanate to determine if the aromatic polyiso(thio)cyanate material will lead to unacceptable bubbling or yellowing in a high refractive index or high Abbe number polymer composition.

Method of preparing low haze polymer compositions for use in high refractive index optical materials

Disclosed are thermally curable film-forming compositions comprising a binder, a flow control system comprising a sag control agent, and less than 5.0 wt.-% of melamine-based components, based on the total weight of resin solids in the film-forming composition, as well as methods for forming a cured coating on a substrate and substrates comprising the cured coating layer.

Thermally curable film-forming compositions providing benefits in appearance and sag control performance

A coating composition includes: (a) a carboxylic acid functional polyol polymer; (b) a melamine-formaldehyde crosslinker reactive with the carboxylic acid functional polyol polymer; (c) an acid catalyst; and (d) a non-aqueous liquid medium. The carboxylic acid functional polyol polymer has an acid value within a range of from 30 to 120 mg KOH/g and a hydroxyl value within a range of from 60 to 150 mg KOH/g. The melamine-formaldehyde crosslinker includes imino and methylol groups that together make up 35 mole % or less of the total functionality of the melamine-formaldehyde crosslinker, and butyl groups and isobutyl groups that together make up 5 mole % or greater of the total functionality of the melamine-formaldehyde crosslinker. The coating composition cures at a temperature of 100° C. or less.

Solvent-borne coating compositions, coatings formed therefrom, and methods of forming such coatings

A curable film-forming composition is provided, comprising: (a) a polymeric binder comprising reactive functional groups; (b) a curing agent comprising functional groups that are reactive with the reactive functional groups of (a); and (c) a polysiloxane resin comprising aromatic functional groups and terminal active hydrogen groups. In certain examples of the present invention, the polymeric binder (a) comprises an acrylic polyol prepared from a monomer mixture comprising a hydroxyl functional monomer, and the curable film-forming composition further comprises a rheology modifier comprising: (1) a non-aqueous dispersion of an internally crosslinked organic polymer; (2) a silica dispersion; and/or (3) a reaction product of an amine and an isocyanate. Also provided are coated substrates that include the curable film-forming compositions described above and methods for forming a composite coating on a substrate.
