DIRECTIONS FOR USE
Preliminary Statement:
Prior to application it is necessary to read the Material
Safety Data Sheet for inbation about precautionary
measures and safety recommendations. Also, for chemical
products exempt from compulsory labeling, the relevant
precautions should always be observed.

Preparation:
The surfaces of the substrate must be dry and free from oil,
grease and dust.

Application:
Application Temperature : 225 to 240 °C
Application System : Hotmelt application systems

When bonding to a substrate with high thermal conductivity
the use of a specific application temperature is required for
good wetting.

Do not heat the product above the specified application
temperature range.
When the product is not in use do not apply heat, this will
degrade the quality of the product and in extreme cases
cause carbonisation. The standby temperature for the
product is approximately 50°C below the application
temperature, but not for longer than 72 hours.
MACROMELT 6812 may absorb moisture from the air. This
will not be apparent in the solid b, but may cause
bubbles on heating and could affect the bond quality. It is
important, therefore, that containers are kept closed and
sealed when not in use.

Cleaning:
Carbonised and set (non thermoplastic) material must be
removed mechanically. Removal of the thermoplastic
material from the hot apparatus can be achieved with
solvent free cleaning system, such as Macromelt 0062
(see separate technical inbation)

Classification:
Please refer to the corresponding safety data sheets for
details on:
  Hazardous Inbation
  Transport Regulations
  Safety Regulations

Storage:
When properly stored in a cool, dry b, with the
container tightly closed when not in use, this product will
have a shelf life of at least 24 months.
