Bond modified polyester heat transfer powder coating

Product description:
A new system of modified polyester powder coating has been developed specially which will accept inks and dyestuffs applied under the heat transfer technology. By the means of heat transfer, almost all kinds of wood grain and some marble effect could be availed after spraying Bond modified polyester powder coating. It is very suitable for the decorating of the aluminum profile and furniture application. Bond modified polyester powder can possess the finish excellent mechanical properties, good weather ability and more clear woody pattern comparing with the Bond HT heat transfer powder.
Features and applications:

    1、High gloss and clarity, excellent leveling;
    2、Excellent powder utilization, so can save the cost of spray processing;
    3、Excellent transfer effect and improving weatherability;
    4、Products comply with GB/T5237.4-2008、AAMA2604 and HG/T2006-2006

Shelf life: Store under cool, dry conditions. It is recommended that the material be used within 12 months of certification below 30℃. It should be rechecked the quality if expire.

Pretreatment: in order to get the best adhesion, the substrate should be treated properly.
Phosphate pretreatment for iron substrate;
Chromate pretreatment for aluminum substrate.
Applying technology: can be applied by manual or automatic electrostatic or tribo spray equipment. Unused powder can be reclaimed and recycled through the coating system
Curing schedule and the key point of the heat transfer:
Bond modified polyester heat transfer powder should be curing 10℃ higher above the normal polyester powder. It is recommended that the baking temperature be 210℃@10min ( metal temperature). The woody color could be adjusted by the heat transfer over temperature. The heat transfer time are range from 3 to 5 minutes.
