Hair Extension Glue Gun                   

Description of glue gun:

Glue guns come in low-temperature and high-temperature (hot-melt) versions. Low-temperature glue guns operate at approximately 120 °C (248 °F) and are well suited when high temperatures are undesirable, such as gluing lace and cloth. High-temperature glue guns operate at approximately 190 °C (374 °F) and produce a stronger bond. Dual glue guns have a switch for both low- and high-temperature use.

In addition to bonding surfaces together, hot-melt glue gun can be used to fill gaps, but the properties that allow gap-filling (high viscosity, high toughness, and so on) keep it from forming an adhesive film as thin and smooth as is possible with other adhesives. (For example, a wood joint properly made with hide glue may be invisible, marked only by a difference in grain at the seam line.) Bonds must be made quickly before the glue has time to harden. Usually it must be applied accurately with the glue gun, as it can not easily be spread, but it is always possible at any time to melt and spread the glue with a heat gun or a householdclothes iron, which helps when bonding larger areas.

Instruction of hot melt glue gun: 

1. Plug the glue gun into an electrical outlet. Make sure it is placed in a safe place, away from flammable items. As the glue gun heats up, a little bit of glue might drip from the end so you won't want to leave it on a wood table, carpet, or other surface that may be damaged by dripping glue.
2. Insert a glue stick into the round chamber at the back of the glue gun. If the glue gun already has a glue stick in the chamber, keep a second one in reserve nearby.
3. Gather the materials you want to glue together. Hot glue works exceptionally well on thick fabrics, dried flowers, Styrofoam, wood and plastics. Since it leaves a thicker residue, it is not the best choice for thin papers, fabrics and ceramics.
4. Check to see if the glue in the gun has melted by squeezing the trigger slightly and touching the tip to a test piece of paper or cloth. If the glue comes out easily, the glue gun has heated up fully. If the trigger is hard to pull, wait a minute more for the gun to heat more completely.
5. Pick up the glue gun and squeeze the trigger slightly while you draw a thin line on one side of the item to be glued.
6. Immediately place the other object to be glued on the glue line, pressing firmly.
7. Hold the two pieces together for about 15 seconds. Test to see if the item still holds when you remove one hand.
8. Let the item set for a few minutes in order to "cure." Once the glue has dried fully, use a fingernail to scrape away any of the excess glue.
