Instructions:
After general cleaning and drying of the components, the product is extruded from the metal hose and coated with glue. The glue comes into contact with moisture in the air and solidifies from the surface to the inside, with a maximum curing time of no more than 24 hours.
Notes:
① For temperature resistant components, they can be cured at room temperature first, and then treated in a damp oven at 50-100 ℃ for 4-8 hours to remove low molecular weight substances and fully cure to ensure the performance of the adhesive.
② When using this product for sealing, the thickness of one accumulation should not be too large. If it is ≥ 3mm, a layered pouring and gradual vulcanization method can be used. The thicker the adhesive accumulation, the longer the complete curing time.
③ After use, the rubber hose should be tightly covered and can be stored for reuse.
Packing Specification: 300ml/piece, 30 pieces/piece, in addition(45g/piece, 100 pieces/piece)
storesave:This product should be stored in a cool and dry environment for a period of one year.
