Disclosed are non-toxic adhesive compositions that are tunable for selective adhesion to an intended substrate under any number of conditions, including a fouled substrate. Methods of making and methods of using are also described.

Adhesive formulations and methods for making adhesive formulations are provided. An adhesive formulation includes at least one oxazoline polymer and casein. Methods of making adhesive formulations include combining at least one oxazoline polymer and casein to form the adhesive formulation. Glue sticks made using these adhesive formulations and methods are also provided.

Easy to use and store. an environmentally friendly binding agent for cellulose-containing materials, without animal products, particularly suitable for use in the production of wood composites. and a composite material product obtained with the use of this binder is disclosed.

The invention relates to a method for coating surfaces by enzymatic reaction of a biopolymer, wherein the method comprises the following steps: a) applying an enzyme to the surface of a substrate, and b) contacting the enzyme with the biopolymer to be deposited, wherein the enzyme cleaves the biopolymer, wherein the cleavage gives rise to at least two cleavage products of the biopolymer having different solubility in a solvent, and at least one cleavage product of the biopolymer having relatively low solubility is deposited on the surface of the substrate, and to a coated article obtainable by the method and to a coating composition comprising a biopolymer and at least one component selected from the group comprising binders, fillers, pigments and/or additives, and optionally a solvent.
