Abstract: A thermosetting-resin-based coating that is capable of forming a substantially flame-resistant barrier upon being exposed to heat. The coating includes a thermoset resin, an acid catalyst having a pKa value of less than 2, a filler selected from glass, mica, talc, perlite, vermiculite and combinations thereof, and an organic-intumescent material. The thermoset coating is at least 75% of the total weight of the coating.

Abstract: A co-injection nozzle pin (20) having downstream and upstream ends. The nozzle pin has therein a central bore (30) including an upstream end (32) adapted to communicate with a first material and a downstream end (34) exiting at the downstream end of the pin. The nozzle pin also has an outer surface (36) including a first portion (38) having a diameter D1, a second portion (40) having a diameter D2, wherein D2 is less than D1 and the first portion is rearward of the second portion. The pin further includes a channel (46) spiralling around the outer surface and being adapted to communicate with a second material. The channel (46) includes a first segment (52) defined in the first portion (38) of the outer surface and increasing in depth as it travels in a downstream direction and a second segment (54) defined in the second portion (40) of the outer surface and decreasing in depth as it travels in a downstream direction.

Abstract: The invention provides a method of co-injection molding. The method includes mixing a plastic inner material and an endothermic-blowing agent to form a core mixture. A plastic outer material is injected from a first injection unit into a co-injection manifold to create a flow of outer material therethrough. The core mixture is injected from a second injection unit into the co-injection manifold to create a flow of core mixture therethrough. The flow of the outer material and the flow of the core mixture are then controlled through the co-injection manifold and into a mold cavity. The core mixture expands as heat is provided for the endothermic-blowing agent to absorb.
