MACROMELT 6812 is a hotmelt adhesive especially suitable for porous substrates such as paper, wood and leather. Technology     Polyamide Product Type   Hotmelt Cure          Physical setting Condition     Thermoplastic Components    One component Application    General assembly Appearance     Amber 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 form, 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.
