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.

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
