  • Patent number: 8501852
    Abstract: The invention relates to a method for improving the wettability and/or adhesivity of plastic surfaces, in particular, to facilitate printing, painting or adhesion. A lubricant is added to the plastic, particularly to improve the processability thereof. According to the invention, a metal soap-free lubricant is used as a lubricant for the plastic. Alternatively, the wettability and/or the adhesivity of the polyamide surfaces can be improved, especially in order to facilitate printing, painting or adhesion, by increasing the number of end groups of polyamides, optionally maintaining metal soaps as lubricants.

  • Patent number: 8436082
    Abstract: An adhesive for filling in gaps between stones, the adhesive including at least 100 weight parts of an unsaturated polyester resin suitable for air-drying, between 1 and 5 weight parts of hydrogenated castor oil, between 0 and 60 weight parts of micron silica, and between 1 and 15 weight parts of an anti-shrinking agent. The adhesive overcomes the disadvantages of conventional marble glue, such as, poor air-drying property, poor shrinkage resistance, and poor permeability. The adhesive of the invention has good permeability, strong shrinkage resistance, and high brightness after being polished, and is not sticky after curing. The invention solves the difficulty of gap-filling of stone by providing a new category of marble glue.

  • Patent number: 8420723
    Abstract: A method of producing a tire mix, including a first mixing step, in which a mix contains at least one cross-linkable unsaturated-chain polymer base, 10 to 100 phr of silica, and 1 to 20 phr of a silane bonding agent in the trialkoxymercaptoalkyl-silane class; and a final mixing step, in which a curing system is added to the mix. The silane bonding agent is used in adsorbed form on 0.5 to 2 phr of zinc oxide, and on 5 to 15 phr of carbon black. At the first mixing step, the mix contains 1 to 5 phr of one or more fatty acid derivatives, and, at the final mixing step, 1 to 2 phr of zinc oxide is added to the mix. The fatty acid derivatives are derived from condensation of a fatty acid, having a carbon number of 16 to 20, with an alcohol having a carbon number of 2 to 6, or with a primary or secondary amine having a carbon number of 2 to 6.
