Frequently Asked Questions
What colors are available?
Standard colors include black, white, and grey. Customized colors are available on request.
How should the adhesive be applied?
Apply in spots, wave-shaped beads, or straight strands depending on surface size and required initial tack, then press firmly with a twisting motion.
What is the service temperature range after curing?
Once cured, HY-722B maintains stable performance between -50°C and +100°C.
How does the adhesive cure?
It cures by water evaporation, which means at least one of the bonded surfaces must be porous.
