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
- Thermogrip® 6363
- Evo-Stik® 7702
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.
