  • AMINE CO-INITIATOR MIXTURE
    Publication number: 20240141078
    Abstract: The invention relates to a co-initiator comprising the aminobenzoate derivative according to Formula (I) and at least one ancillary amine, wherein the reactivity and solubility of said co-imitator in UV-curable resins is sufficiently high that the co-initiator can be used in UV radiation curing processes. Formula (I) wherein R1 and R2 independently represent methyl or ethyl groups; and j, k, l and m are independently 0 to 20.

  • Oil or gas drilling tool block with textured coating
    Publication number: 20150115635
    Abstract: An oil or gas tool block with an advanced textured coating produced by automated electro spark deposition equipment. A die insert includes a substrate onto which a gripping surface is formed. The gripping surface is a textured coating electro-deposited on the substrate. The textured coating includes a cobalt-based alloy supplied directly by the welding electrode, allowing the continuous build-up of material typically in the range of 0.001-0.040 inches. The cobalt-based alloy comprises a blend of chromium, cobalt, iron, manganese, molybdenum, nickel, and silicon. One or more die inserts, whether blank or textured, can be stacked to form a tool block. In a process for making the die insert, the substrate is texture-coated using electro-spark deposition in two passes, including a first coating pass and a second coating pass. Hard coating may follow to thereby form a gradient of layers.
