PCL hot melt adhesive application
Problem Phenomenon
PCL hot melt adhesive bonding strength and open time, application performance balance.
Cause Analysis
PCL hot melt adhesive bonding strength; open time; curing speed; temperature resistance; substrate matching.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Formulation optimization for strength; ②Open time regulation; ③Curing management; ④Substrate testing; ⑤Application matching.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The performance balance of PCL hot melt adhesive is the key to application; both formulation and process are emphasized; testing ensures bonding quality.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
