Abstract: Production of an adhesive layer containing at least one isocyanate reactive polymer and a solid surface-deactivated polyisocyanate and to increase its shear strength, comprises heat treatment at a temperature, preferably ≥ 40 degrees C above the drying temperature. The shear strength of the resulting adhesive joint is at least 10% higher than without the heat treatment. A process for the production of an adhesive layer and to increase its shear strength comprises: (A) preparation of an aqueous dispersion or solution containing at least one isocyanate reactive polymer and a solid surface-deactivated polyisocyanate; (B) application of the aqueous dispersion or solution onto a substrate; (C) production of an adhesive layer by removal of the water by drying at 20-95 degrees C (preferably 50-95 degrees C); and (D) performing heat treatment where the layer is heated continuously, stepwise or directly to a temperature, preferably at least 40 degrees C above the drying temperature. The shear strength of the resulting adhesive joint is at least 10% higher than without the heat treatment and the isocyanate reactive polymer and the solid surface-deactivated polyisocyanate are chosen such that following step (C), the adhesive layer has a loop tack of at least 2 N/inch.

Abstract: A method for manufacturing containers for growing plants, comprising an initial step of reducing plastics and fired clay to granules and a final step of releasing the containers from molds. The method includes, in order of sequence, the intermediate steps of preparing a mixture of the granules, introducing the mixture into the molds, heating the mixture until the melting temperature of the material is approximately reached, holding the mixture at that temperature, and cooling the mixture. A container produced with the method includes uniformly distributed fired clay granules and reticular formations of plastics that mutually bind the granules. The invention overcomes the drawbacks of the prior art, by providing containers that combine the best characteristics of earthenware and plastic containers, respectively.
