Transpareant yellow-brown liquid. Its color does not affect the bonding strength. Products may contain lamellar sediment.

Product Application:
Two-component adhesive must be used within the applicable period after putting after putting in RFE. The length of applicable period is not only related to the polymer content of adhesive, but also other relevant components ( Like reisn, antioxygen, plasticizer, solvent, etc. When close to the applicable period, usually a few hours or one working day, adhesive becomes more difficult to operate, and viscosity rises soon, Finally, it becomes the irreversible jelly. 100 quality adhesive, Hydroxyl polyurethane ( Polyurethane account for around 20%), RFE dose 4-7. Chloroprene rubber ( Rubber account for around 20%), Our RFE dose 4-7.
