FILM AND SEED COATING COMPOSITION

A film coating composition, and seed coating composition formed comprising the film forming composition. The film coating composition comprises rosin resin and/or starch derivative and wax dispersion. The sum of rosin/starch and wax in the film coating composition being in the range 2 to 60 wt.%. The seed coating formulation optionally comprises an agrochemical active and/or nutrient, and is applied to seeds or bulbs for wet and dry flowability, abrasion resistance, dust off, germination, plantability and colour retention. In particular, the seed coating composition provides said properties whilst essentially or completely microplastic free. There is also provided a method of making the formulations, and for treating seeds or bulbs with seed coating formulation.

Coating providing modulated release of volatile compositions

Described are modulating coatings that are configured to provide an improved release profile of a volatile composition from a base material, wherein the modulating coating includes a barrier substance that is configured to hinder a release of the volatile composition through the modulating coating, and a hygroscopic substance that is configured to facilitate the release of the volatile composition through the modulating coating.

Removal of paint from porous, smooth, and mineralogically fragile surfaces

Compositions and methods of the invention are directed to the removal of solid films, and particularly paint layers, from substrates, and particularly smooth, porous, and/or mineralogically fragile substrates such as sandstone. The compositions include cooked aqueous solutions of starch. The compositions can advantageously remove paints and other unwanted solid films from these and other substrates without damaging the substrate itself.

AN INTERMEDIATE LAMINATE PRODUCT, AN EXPANDED LAMINATE STRUCTURE, AND PROCESS MANUFACTURING THEREOF
20170361573 · 2017-12-21 · ·

An intermediate laminate product includes a first paper layer including lignocellulose fibres, and a dry coating layer applied to one surface of the first paper layer, the coating including expandable microspheres having an expansion temperature (T.sub.E), at least one polysaccharide, and a plasticizing additive which is capable of forming a thermoplastic blend with the polysaccharide. An expanded laminate structure includes the intermediate laminate product and a second paper layer comprising lignocellulose fibres, which is attached to the dry coating by heat lamination. A liquid packaging board includes the expanded laminate structure and a liquid barrier layer. A process for forming the expanded laminate structure includes applying a second paper layer to the coating of the intermediate product at a second temperature (T2), which is above the expansion temperature (T.sub.E) of the microspheres, whereby the microspheres expand, and at which the plasticizing additive causes plasticizing of the polysaccharide, to form a thermoplastic blend.
