GENERAL DESCRIPTION
Plascoat PPA 662 is a polyolefin-based alloy, designed for application by a variety of techniques to give a protective coating with excellent resistance to aqueous environments. The coating gives excellent adhesion without the need for an adhesion priming coat and can withstand steady or cycling temperatures between -40°C and +65°C.
Plascoat PPA 662 is available in a limited range of colours, including Black, White, Grey & Yellow.

TYPICAL USES
Reinforcement cages, tank lining Battery boxes Coating of pipes/fittings, wirework
GUIDE TO TYPICAL COATING CONDITIONS
Recommended Pretreatment: Ensure metal is clean by thorough degreasing and removal of mill scale. To get the full benefits of the material, the metal can be blast cleaned to Swedish standard SA 2½-3. Phosphating will assist the long term corrosion resistance in aggressive environments.
Batch Operation: Metal preheat temperature minimum 280°C. Dipping time 5-20 seconds. A post-heat cycle at 170°C may be required on light items. Air cool (satin finish) or water quench (semi-gloss finish).
These values are only intended as a guide and will vary according to metal thickness and type.
For typical properties of the coating see below.
HEALTH AND SAFETY
Plascoat PPA 662 is supplied as a finely divided powder. Whilst there are no known health hazards associated with PPA 662, normal handling precautions for dealing with fine organic powders should be taken - i.e. excessive dust generation and inhaling of the powder should be avoided. Facilities may be required for removing excess dust from the working area during the coating of more difficult items.
As with all polymeric powders, the material can ignite if brought into contact with a high temperature source or ignition - particularly in the fluidised condition.
Reference should be made to Plascoat Health and Safety Data Sheet HS501, available on request.Should the coating be required for contact with food or potable water, further details should be obtained from Plascoat. |

STORAGE
Stored in a clean, dry area at 10-30°C and out of sunlight, the material should not deteriorate. However, in the interest of good housekeeping, old stocks should be used first.
