The present disclosure relates to composite materials comprising a resin and at least one sheet that comprise optionally cellulose filaments (CF), fillers and optionally reinforcing fibers as well as methods for the preparation thereof. The methods comprise impregnating the sheets comprising the cellulose filaments, fillers and optionally the reinforcing fibers or a stack thereof with resin. The composite materials can optionally comprise at least one other sheet, the at least one other sheet being different from the at least one sheet and comprising fibers chosen from wood pulp, fiberglass, natural fibers and mixtures thereof. The sheet can also be in the form of a panel of a preform.

The present invention relates to a coating composition and method of manufacturing said coating composition. The coating composition is a two-component coating composition for construction surfaces. The present coating composition is effectively bonded to the surface without an additional application of intermediate layer overcoming the existing problems associated with conventional concrete surface treatment methods.

The present disclosure relates to coating compositions, kits, and methods of applying the same, for use with fireproofing materials. The coating compositions are effective to control the drying rate and shrinkage of fireproofing materials. The coating compositions are also able to be applied to fireproofing materials shortly after these materials have been applied to a substrate.

Provided is a ceiling tile coated on at least one surface with an acoustically transparent coating which creates pores at the tile surface and comprises a high Tg polymeric binder, titanium dioxide, and particles selected from the group consisting of void latex particles, hollow glass beads, calcium carbonate, calcium magnesium carbonate, calcined clay and any combination thereof. Compositions for acoustically transparent coatings and methods for making a substrate surface acoustically transparent are provided as well.
