A method for making three dimensional structures using photolithography and an adhesively bondable material is disclosed. A thiol-ene-epoxy (OSTE(&#x2212;)) material undergoes a first reaction upon partial irradiation in a pattern to become a partially cross-linked polymer network. Non-cross-linked parts are dissolved in a solvent and removed. An initiator is added to activate the cross-linked polymer network so that it becomes adhesive and can then be covalently bound to another object to form an article. The method can be utilized to manufacture an article with a complicated three dimensional shape in an easy way.

There is provided a method of coating a substrate comprising at least one secondary amine, by contacting the substrate surface with a compound comprising at least one carbon-carbon double bond, wherein an electron withdrawing group is on at least one side of the carbon-carbon double bond, so that a complex is formed between nitrogen in the secondary amine and the carbon-carbon double bond. Then a reaction is initiated to form a covalent bond by reaction of nitrogen in the secondary amine and the carbon-carbon double bond, by subjecting at least a part of the formed complexes to actinic radiation, wherein the wavelength of the actinic radiation is adapted to be absorbed by the complex. When a further top-coat is added, the resulting surface has a high hardness, and the scratch resistance is improved.

The invention relates to a cement formulation with two liquid components. This alleviates the problems which result from dust generation where a powdered cement component is employed. Furthermore, the cement may be formed with conventional liquid handling and mixing equipment. The cement binder formulation includes a plasticizer. As the plasticizer is non-volatile, it remains an integral part of both the formulation and the final product obtained after application and drying of that formulation.
