Polyflake® The Solution
Before you dispose of corroded, expensive or irreplaceable equipment - consider repairing and restoring it to original condition using Polyflake®.
Developed in Europe and made from chemical resistant highly modified resins, mixed with glass flakes, Polyflake® can repair, rebuild and protect equipment to original standards at a much lower cost than replacement.
What Are Polyflake® Coatings?
These are formulations of glassflakes and corrosion/chemical resistant polymer resins. Compared to other chemical and corrosion resistant resins available, Polyflake® is the natural choice. By a controlled polymerisation process the resin is bonded to the original bare metal, and in a three-phase process the corroded or damaged machine parts are restored to their original specifications The formulation can be varied to produce spray, brush or trowel grades to meet the specific needs of each application, and suit the corrosive, chemical and mechanical conditions to be encountered. Polyflake® can be applied to most metal surfaces, concrete, synthetics and substantially increases the operational life of all treated equipment.
- Linings and coatings containing glassflakes show superior resistance to abrasion and impact. They enhance a vacuum bond with the substrate to the extent that no undercutting will occur.
- Because the glassflakes are only 3-4 microns thick, there can be as many as 300 parallel overlapping glassflakes in a 2mm thick lining - thus a very tortuous path is offered to liquid of vapour penetration.
- Examination of underlying surfaces after removal of the Polyflake® coatings showed that no under-film oxide had been formed. This proves that the product is highly resistant to penetration of oxygen and other corrosive chemicals.
The flakes also perform two other very important functions:
- Glassflakes control the shrinkage stress normally associated with resins during their cure, and they reduce the co-efficient of expansion of the resin to match closely that of aluminium.
- Coupled with the already excellent adhesion properties, the glassflakes enable the bond with steel to be maintained at temperatures as high as 170 degrees C.
