PETG solvent bonding poor effect
Problem Phenomenon
When PETG products are bonded to each other with solvent, the bonding strength is insufficient and they easily come apart.
Cause Analysis
The selected solvent does not match and cannot effectively dissolve the PETG surface, application uneven or volatilization too fast, bonding surface not clean.
Solution
Select a suitable solvent (dichloromethane, MEK/THF mixed solvent); ensure the bonding surface is clean and flat; control volatilization and ambient temperature.
Key Takeaway
PETG solvent bonding requires selecting a suitable solvent system and controlling bonding conditions.
