  • Patent number: 9809899
    Abstract: A method of coating an electroplating rack used for supporting non-conductive substrates during a plating process. The method comprises the steps of contacting at least a portion of the electroplating rack with a plastisol composition, the plastisol composition having dispersed therein an effective amount of an additive; and heating the electroplating rack with the plastisol composition thereon to a suitable temperature and for a sufficient time to cure the plastisol and form a solid insulating coating on the electroplating rack. The coated electroplating rack may then be used for mounting non-conductive substrates for subsequent metallization steps.

  • Publication number: 20040067440
    Abstract: An actinic energy ray-curable resin is obtained by reacting (c) an epihalohydrin with hydroxyl groups of a linear epoxy resin (A′) which is a product of the polyaddition reaction of (a) a bifunctional hydrogenated bisphenolic epoxy compound with (b) a compound having at least two carboxyl groups in its molecule to obtain a polynuclear epoxy resin (A″) having epoxy groups in its terminal and side chain and further reacting (d) an unsaturated monocarboxylic acid with an epoxy group of the polynuclear epoxy resin (A″) to introduce a photopolymerizable unsaturated group therein and further reacting (e) a polybasic acid anhydride with a hydroxyl group of the polynuclear epoxy resin to introduce a carboxyl group therein. A photocurable and thermosetting resin composition capable of being developed with an aqueous alkaline solution is obtained by mixing this actinic energy ray-curable resin with a photopolymerization initiator, a diluent, and a polyfunctional epoxy compound.
