Araldite pt 910

Example 2

The mixture was composed of 600 parts of Uralac® P3490 having T_g of 69° C., 45 parts of Araldite® PT-910 (Huntsman) having melting point (DSC, ISO 11357-1) 90-102° C., 15 parts of Resiflow PV 5 (Worlée-Chemie GmbH), 8 parts of Accelerator DT-3126 (Huntsman), 7 parts of Benzoin and 10 parts of short carbon fibers. The carbon fibers used had an average length of 60 μm and can be obtained under the product designation Tenax®-A HAT M100 (Toho Tenax Europe GmbH). All components were premixed in a high-speed mixer for 1 min and then extruded in a twin-screw ZSK-18 extruder at a screw speed of 400 rpm with a rear-zone temperature of 90° C. and a front-zone temperature of 100° C. In an alternative setting of the extruder, a temperature gradient of 40 to 100° C. and a cooling device for the feeding area was used. The compound obtained was then cooled down, granulated and fine ground to obtain a powder having a D50 of less than 100 μm. The powder can be used in a 3D printer, for example in a SLS laser sintering 3D-printing machine.

Example 1

The mixture was composed of 600 parts of Uralac® P3490 (DSM), a saturated carboxylated polyester resin, 45 parts of Araldite® PT-910 (Huntsman), 8 parts of Accelerator DT-3126 (Huntsman), 7 parts of Benzoin and 13 parts of charge control agent salicylic acid DL-N24 (Hubei DingLong Chemical Co., Ltd). This composition gave a transparent formulation. For different colours (Cyan, Magenta, Yellow, Black and White) 33 parts of Heliogen Blue K7090 (BASF) for cyan, 33 parts of Cinquasia Violet L5120 (BASF) for magenta, 106 parts of Sicopal Yellow L1100 (BASF) for yellow, 33 parts of Printex 90 BEADS (Orion Engineered Carbons) for black or 200 parts of TI Select TS6200 (DuPont) for white were added. All components were premixed in a high-speed mixer for 1 min and then extruded in a twin-screw ZSK-18 extruder. The compound obtained was then cooled down, granulated, fine ground and classified to obtain a powder having a D50 of up to 12 μm if not otherwise described.

Hardening (curing the coating layer on the substrate) was done at a temperature of 200° C. for 10 minutes.

All components were premixed in a high-speed mixer for 1 min and then extruded in a twin-screw ZSK-18 extruder at a screw speed of 400 rpm with a rear-zone temperature of 80° C. and a front-zone temperature of 90° C. In an alternative setting of the extruder, a temperature gradient of 40 to 100° C. and a cooling device for the feeding area was used. The compound obtained was then cooled down, granulated and fine ground to obtain a powder having a D50 of less than 80 μm.
