Glassflake has an extensive history of use in liquid applied coatings, dating to a first introduction in the 1950s - with enhancements in the manufacturing technology of glassflake materials, the same property enhancements are now available to the powder coating formulator. Performance improvements such as: moisture vapour barrier, fire retardancy & mar resistance can now be provided to coating systems, irrespective of application technology. Examples of the use of glassflake technology use in powder coatings include providing improved corrosion protection to steel substrates, through to enhanced durability in architectural powder coatings to conform to AAMA 2605 standards. This presentation aims to illustrate how glassflake can be used as a performance enhancer in all coating systems and how these improvements can be best utilised in powder coatings. Linked to advances in glassflake manufacturing technology, the presentation will also address advances in effect pigment technology. The availability and benefits of borosilicate effect pigments based on sub-micron glassflake substrate will be discussed.
