Processes of making a non-woven glass fiber mat are described. The process may include forming an aqueous dispersion of fibers. The process may also include passing the dispersion through a mat forming screen to form a wet mat. The process may further include applying a carbohydrate binder composition to the wet mat to form a binder-containing wet mat. The binder compositions may include a carbohydrate, a nitrogen-containing compound, and a thickening agent. The binder compositions may have a Brookfield viscosity of 7 to 50 centipoise at 20 C. The thickening agents may include modified celluloses such as hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC), and polysaccharides such as xanthan gum, guar gum, and starches. The process may include curing the binder-containing wet mat to form the non-woven glass fiber mat.

According to one or more embodiments, a method of making an antifouling coating includes forming a polythioaminal polymer by reacting a fluorinated primary amine with an aldehyde to form an intermediate imine, and then reacting the intermediate imine with a dithiol. The method further includes depositing the polythioaminal on a substrate, and increasing a temperature of the polythioaminal deposited on the substrate to crosslink the polythioaminal and increase a contact angle of the substrate with crosslinked polythioaminal.

The present disclosure refers to an acid-cured coating composition with low free formaldehyde emission and preparation method thereof. The acid-cured coating composition comprises an alkyd resin, an amino resin, and an acetoacetyl-functional silicon-based resin, wherein upon curing, the amino resin itself releases at least 0.8 wt % of formaldehyde, based on the weight of the amino resin; weight ratio of the alkyd resin and the amino resin is in a range of from 70:30 to 45:55. The present disclosure also refers to a coated article.
