[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. The various polymer compositions provide varying melt temperatures, melt viscosities, set-time, surface flow, surface wettability and bond strength.
Synonyms and Related Terms
Holt melt glue sticks; Hot glue; Hot-melt adhesive (HMA)
Physical and Chemical Properties
EVA based HMAs tend to have a long shelf-life and do not loose volume on cooling. Also the HMAs usually do have any specific disposal requirements. Some HMA formulations are susceptible to oxidation and UV degradation.
EVA based formulations include:
- 3M Jet Melt Glue Sticks No. 3764
- Evo-Stik® 7702
- Thermogrip® 6363
- Maxistick 6300 Hot Melt Glue Stick
Low temperature hot-melt glue (3M #3792 LMQ) is used for paperboard and foam
High temperature hot melt glue (3M #3748Q) is used for Coroplast.
