A sol comprising a solvent, an alkoxide, a catalyst, and a protein, wherein the protein is a plant-derived protein, an animal-derived protein, a fungus-derived protein, or any combination thereof. The sol may be used to immobilise pigment. The sol may be used to form a fluid resistant or impermeable barrier and/or a free-standing unsupported structure.

The present invention relates to a method of providing thermal and/or acoustic insulation to a structure, comprising the steps of: providing a substrate which comprises fibres; applying the substrate to the structure; blending the substrate with a binder composition before, during or after application of the substrate to the structure; allowing curing of the binder composition after the substrate and the binder composition have been applied to the structure; wherein the binder composition comprises at least one hydrocolloid. The present invention also relates to an insulated structure obtainable by said method.

The invention features a reinforcement element including a continuous paper strip having a first side and a second side, a first adhesive composition disposed on at least one of the first side and second side.

The invention further features a paper reinforced tape including a continuous paper strip, a continuous paper backing layer and a first adhesive composition disposed between the continuous paper strip and the continuous paper backing layer thereby adhering the continuous paper strip to the continuous paper backing layer.

The paper reinforced tapes and reinforcement elements of this invention have improved repulpability, recyclability, compostability and biodegradability. Further, these reinforcement elements and paper reinforced tapes, despite being predominately paper, unexpectedly provide excellent container reinforcement properties and further can be used as opening tapes, closing tapes and carrying handles.
