Performance and parameters Name: JL-608AB adhesive appearance: transparent liquid body viscosity: 5000-8000cps operation time: (with 100 grams of adhesive 20-30 minutes) curing speed: (25 ℃, 1-2 hours) proportion of mixing (A: B weight ratio of A: B = 1: 1) Tensile shear strength: (25MPa) adjustable: 20 24 1:1 ≥ 25 Scope of application Poly 608 high-temperature AB adhesive is particularly suitable for color TV high-voltage packages, medical equipment, oil drilling, PCB boards, mining equipment, wear-resistant ceramic sheet, high-current transformers, induction cooker base plate, filters, insulating panels, micro-motors, confidential potting, cable joints, such as bonding and potting.
Methods of use ● Poly 608 high temperature AB adhesive to be bonded to the fixed parts need to be kept dry, clean; remove the substrate surface loose material, sandblasting, electric grinding wheel, steel wire brushes or coarse sandpaper and other ways of sanding, to improve the repair of the surface roughness, the use of acetone detergent wipe, in order to clean the surface of the next in order to enhance the adhesive force. ● Poly 608 high temperature AB adhesive according to the proportion of the amount, A, B agent mixing needs to be fully stirred to avoid incomplete curing; mixing evenly after the injection of glue in a timely manner, and try to use in the time available to use the glue has been mixed; Poly 608 high-temperature transparent AB adhesive curing process, please clean the containers used in a timely manner and utensils, so as not to glue solidified in the utensils on the items.
