Publication number: 20230374238Abstract: There is provided a method of coating a substrate comprising at least one chemical group, by contacting the substrate surface with a compound comprising at least one carbon-carbon double bond or a mixture of a first monomer M1 and a second monomer M2. Then a reaction is initiated to form a covalent bond by reaction of the photoactive groups 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 photoactive group. The method is to a large extent resistant to inhibition of impurities in the substrate surface. A greater uniformity of the elastic modulus throughout the substrate and the added layers can be achieved. When a further topcoat is added resulting surface has a high hardness, and the scratch resistance is improved. When a topsheet is applied the abrasion resistance is improved.Type: ApplicationFiled: October 28, 2021Publication date: November 23, 2023Inventors: Tommy HARALDSSON, Henrik MIKAELSSON, Jonas HANSSON, Carl Fredrik CARLBORG

Publication number: 20230048969Abstract: There is provided a method of coating a substrate comprising applying a first mixture where the first mixture reacts to form covalent bonds to the substrate surface and where the unreacted parts of the first mixture undergo diffusive mixing with a second layer, which is applied on top of the first mixture. This avoids creation of a weak layer, which may otherwise give lower adhesion. The adhesion as well as mechanical properties including the scratch resistance are improved.Type: ApplicationFiled: January 22, 2021Publication date: February 16, 2023Inventors: Tommy HARALDSSON, Carl Fredrik CARLBORG, Henrik MIKAELSSON, Jonas HANSSON

Patent number: 11143959Abstract: A method for making three dimensional structures using photolithography and an adhesively bondable material is disclosed. A thiol-ene-epoxy (OSTE(?)) 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.Type: GrantFiled: August 24, 2017Date of Patent: October 12, 2021Assignee: MERCENE LABS ABInventors: Carl Fredrik Carlborg, Tommy Haraldsson, Henrik Mikaelsson, Noriyuki Masuda

Patent number: 10975246Abstract: 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.Type: GrantFiled: March 4, 2019Date of Patent: April 13, 2021Assignee: MERCENE COATINGS ABInventors: Tommy Haraldsson, Henrik Mikaelsson, Carl Fredrik Carlborg, Jowan Rostami

Patent number: 10040944Abstract: Modification of polymer surface properties is disclosed by using a method comprising providing a liquid curable monomer formulation comprising a surface-active compound so that the surface active component is attracted to or repelled from at least a specific part of a master surface and is fixed in the polymer article upon curing. The method is carried out in one step and is thus simple and inexpensive to carry out.Type: GrantFiled: January 12, 2015Date of Patent: August 7, 2018Assignee: MERCENE LABS ABInventors: Gaspard Pardon, Tommy Haraldsson, Wouter Van Der Wijngaart

Patent number: 9862857Abstract: An object with a coating comprising: a) covalent bonds formed by reaction of a thiol group and a carbon-carbon double bond, b) covalent bonds formed by reaction of a thiol group and epoxide group, c) covalent bonds formed by a reaction of a carbon-carbon double bond and an epoxide group, said coating comprising a first primer coating and a second coating, said coating comprising covalent bonds between said first and second coatings, said first primer coating comprising covalent cross links between compounds, in the first coating the fraction (r3=ta/tc) of unreacted thiol groups (ta) to thiol groups which have reacted to form a covalent bond (tc) does not exceed 0.11, wherein the half height peak width of tan delta does not exceed 30° C. Advantages of the dual cure composition is that excellent strength is obtained and that the second curing is slow compared to the first initial curing.Type: GrantFiled: September 1, 2016Date of Patent: January 9, 2018Assignee: Mercene Labs ABInventors: Carl Fredrik Carlborg, Tommy Haraldsson

Publication number: 20170351175Abstract: A synthetic paper is manufactured with a method comprising the steps of: a) providing at least two types of pho to-polymerizable monomers, b) exposing the volume to a three-dimensional light pattern to induce a polymerization reaction, and c) removing uncured monomer to create an open microstructure. The volume comprises at least one monomer comprising at least two thiol groups and at least one monomer comprising at least two carbon-carbon double bonds, where the ratio (r1) between the number of thiol groups and the number of carbon-carbon double bonds fulfils one of: 0.5?r1?0.9 and 1.1?r1?2. One advantage is that off stoichiometry creates an edge effect giving better defined boundaries between exposed and unexposed parts in the volume and giving a possibility to create thinner micro pillars. Another advantage is that it is easy to bind molecules to the surface to obtain desired surface properties.Type: ApplicationFiled: January 18, 2016Publication date: December 7, 2017Inventors: Jonas Hansson, Hiroki Yasuga, Wouter Van Der Wijngaart, Tommy Haraldsson
