DOT Shipping Classification: Non-hazardous.


Handling suggestions: When substrates with high heat conductivity shall be bonded the use of a given application temperature is necessary for good wetting. The substrate surface should be free of dust and cleaned with a suitable solvent so that there is no fat and oil.

Do not heat the product over the mentioned application temperature range. Without using do not heat the product for a long time, because the quality can decrease or extremely the product cokes. The standby temperature is 80 °C.


EsterMelt 525 may adsorb moisture from the air. This will not be obvious in the solid form, but could cause foaming as the adhesive is melted which may result in poor bonds. Re close the container tightly as soon as sufficient adhesive has been removed for immediate use.


Apparatus cleaning: Remove very strong coked and not thermoplastic rests of hot melt mechanically.
