Note:

·Curing conditions: After thoroughly mixing the liquid adhesive components A and B in a 1:1 ratio, mold the material in a 140 mm × 120 mm × 2 mm die at 175°C for 5 minutes.

·Solid adhesive: vulcanized under a 25×25 mm mold, using a 150 mm × 140 mm die, with vulcanization at 175°C for 5 minutes.

·This data is for reference only; the actual material properties and molding process parameters shall be subject to those provided by our Technical Department.

Packaging Specifications

Suitable for 200 kg/drum and 20 kg/drum.

Precautions

·Store at room temperature in a dry, well-ventilated indoor location, away from direct sunlight; shelf life is 12 months.

·During storage and use, contact with compounds containing N, P, S, Sn, or Pb can poison the platinum catalyst, thereby affecting the sulfidation process.
