Operation and Safety
  • Before use, thoroughly mix components A and B in a 1:1 ratio. Stir for 5 minutes. It is recommended to use it after 5-10 minutes of vacuuming at -0.09MPa~-0.08MPa
  • Temperature and curing time: 25 ℃, no flow starting from 120 minutes; Fully cure at 120 ℃ for 30 minutes.
  • The mixed adhesive should be sealed, stored, and used up within a safe operating period, otherwise it will slowly solidify and cause waste.
  • The curing speed of the adhesive is related to temperature to a certain extent, and curing will be slower at low temperatures.
  • This product is not a hazardous material, but do not enter or eye contact. If accidentally splashed, rinse with plenty of water.
  • The A and B components of the colloid must be sealed and stored to prevent leakage during transportation!
  • During the vulcanization process, this product should avoid contact with organic compounds such as N, P, S, ionic compounds containing heavy metals such as Sn, Pb, Hg, Sb, Bi, As, as well as organic compounds containing unsaturated groups such as acetylene groups. Otherwise, it may cause poor adhesive curing. Therefore, compatibility testing between silicone rubber and the substrate should be conducted first before use.
Color and packaging

A group of 20Kg for component A and 20Kg for component B (small bucket),

Or a set of A component 200Kg and B component 200Kg (large barrel)

Storage and expiration date

Store in a dry place for a storage period of 12 months. If it expires, it needs to be retested and can be reused after passing the inspection.

This type of product belongs to non hazardous goods and can be transported as general chemicals.
