Frequently Asked Questions
What Permabond adhesives are compatible with the DD50MLCOMBOGUN?
The DD50MLCOMBOGUN is compatible with all Permabond 2-part adhesives supplied in 50ml dual cartridges with 1:1 or 2:1 mix ratios. This includes Permabond ET series 2-part epoxies (e.g., ET515, ET5428) and PT series 2-part polyurethanes (e.g., PT321) in 50ml cartridge format. Verify the mix ratio of your specific adhesive cartridge before use.
What is the difference between a 1:1 and 2:1 mix ratio cartridge?
The mix ratio refers to the volume ratio of Part A to Part B in the adhesive cartridge. A 1:1 ratio means equal volumes of both parts are dispensed simultaneously. A 2:1 ratio means twice the volume of Part A is dispensed for every one part of Part B. The DD50MLCOMBOGUN is designed to accommodate both ratios — the cartridge geometry and plunger design automatically dispenses the correct ratio for each cartridge type.
Do I need a static mixer with this dispensing gun?
Yes — a static mixer tip is required to mix the two adhesive components as they are dispensed. Permabond 2-part adhesive cartridges typically include one static mixer per cartridge. Additional static mixers are available separately. Always attach a new static mixer before beginning dispensing, and leave the used mixer attached to the cartridge between uses to prevent the mixed adhesive at the tip from curing back into the cartridge.
How do I prevent the cartridge from dripping between uses?
After dispensing, release the trigger and allow the pressure to equalize before removing the cartridge. Leave the used static mixer attached — the cured adhesive in the mixer tip acts as a seal. Store the cartridge with the mixer attached in a cool location. When resuming use, dispense a small amount to purge any partially cured material from the mixer before applying adhesive to your workpiece.
