Description
[3M, St Paul, MN] A brand name for a thermoplastic adhesive that is applied in the molten state and becomes solid as it quickly cools. Special devices, often sold as glue guns, hold the solid stick while provide heat at the tip to melt the outer section for application.The original 3M brand of Hot-melt Glue Sticks are composed of a copolymer of ethylene vinyl acetate (EVA at 65%) blended with a hydrocarbon resin (terpene-phenol at 30%). Currently many varieties of hot-melt adhesives (HMAs) are available that provide varying melt temperatures, melt viscosities, set-time, surface flow, surface wettability and bond strength.
Synonyms and Related Terms
Hot melt glue sticks; Hot glue; Hot-melt adhesive (HMA)

Physical and Chemical Properties
EVA based HMAs:
- Have 2 year long shelf-life and do not loose volume on cooling
- Do have any specific disposal requirements
- May be susceptible to oxidation and UV degradation with age
Forms/Sizes
EVA based formulations include:
- 3M hot melt adhesive 3748
- 3M Scotch-Weld Hot melt adhesive 3762Q
- 3M Jet Melt Glue Sticks 3764
- 3M Scotch-Weld Low melt glue
- 3M Quadrack hot glue
- Maxistick 6300 Hot Melt Glue Stick
