Publication number: 20110190452Abstract: The invention relates to a method for bonding, onto a carrier, active molecules having an activity either against undesirable organisms or phenomena, or promoting a desired phenomenon. The method comprises: preparing a chemical composition containing at least cationic micelles each including at least one active molecule; impregnating the carrier with the cationic micelle chemical composition; bonding the active molecules onto the carrier by creating at least one electrostatic bond between the cationic micelles and the carrier. The invention also relates to an active element including a carrier and active molecules bonded onto said carrier and having an activity either against undesired organisms or phenomena, or promoting a desired phenomenon. The active element includes cationic micelles bonded onto said carrier by at least one electrostatic bond and each including at least one active molecule.Type: ApplicationFiled: August 13, 2008Publication date: August 4, 2011Applicant: LONG LASTING INNOVATION - L2IInventors: Jean-François Fafet, Georges Antunes, Philippe Myard

Publication number: 20110178228Abstract: The present invention relates to resin syrup, which comprises a high-molecular-weight acrylic material containing a carboxyl group, and comprises a room-temperature-curing initiator and a high-temperature-curing initiator, and it also relates to an artificial marble containing a hardened form of the resin syrup, and to a production method for the same. The present invention can provide resin syrup having outstanding curing efficiency and a viscosity suitable for press molding by a process such as maturation because of the inclusion of the high-molecular-weight acrylic material containing a carboxyl group, the room-temperature-curing initiator, and the high-temperature-curing initiator, and it can provide an artificial marble containing a hardened form of the resin syrup, and a production method for the same.Type: ApplicationFiled: September 4, 2009Publication date: July 21, 2011Inventor: Hang Young Kim
