T&E products include more than 20 types of cartridges and accessories and more than 180 types of needles, so it is easy to get confused with so many products, if you are using dispensing accessories for the first time or you have found that the accessories you are using are not quite suitable, please refer to our suggestions:
I. Four guidelines:
Small point - small gauge needle, low pressure, short duration
Big point - large needle, higher pressure, longer time
Thick glue - slanted needle, higher pressure, set time as needed
Water-based liquids - small needle, lower pressure, set time as needed
II. Fluids requiring special settings
Instant glue: For water-based instant glue, use safety piston and Teflon lined metal needle; for thick instant glue, use conical bevelled needle; for flexible, use PP needle.
UV adhesive: Use amber coloured syringe, white piston and slanting needle (UV shielding). If you use other kinds of needles, please order UV shielding needles from our company.
Light curing adhesive: Use black opaque syringe, white piston and UV shielding needle.
Anaerobic adhesive: Use 10CC syringe and white PE piston.
Sealants and pastes: If the white piston bounces back badly, please change to the safety type and use a slanted needle.
