PLASCOAT PPA 583

Performance Polymer Alloy Coating

 

GENERAL DESCRIPTION

 

Plascoat PPA 583 is a powder based on a blend of polyolefins and is supplied for the fluidised bed coating of metal articles. It melts at a lower coating temperature than other coating powders. This has been achieved without loss of stress crack resistance or loss of thermal stability. The coating has no adhesion to metal but offers a water resistant porous free coating. Plascoat PPA 583 is therefore ideal for coating items which will be exposed to sunlight for prolonged periods of time but which are not permanently fixed in position. Furthermore the coating has an attractive low gloss finish.

 

TYPICAL USES

 

Lawn mower handles, Display racks

 

GUIDE TO TYPICAL COATING

CONDITIONS

 

Recommended Pretreatment:

Ensure metal is clean by thorough degreasing and removal of rust and mill scale.

 

Batch Operation:

Metal pre-heat temperature: 270°C min.

360°C max

Dip for 3-5 seconds.

Post-heat cycle may be required to obtain smooth finish on thin metal. Water quench optional.

 

Automatic coating plant:

Pre-heat oven 280°C for 2 to 4 minutes

Dip 3 - 5 secs

Post-heat oven 150°C for 2 to 4 minutes

Water Quench Optional

 

The process temperature used should be the minimum to achieve an acceptable surface finish. Overheating may cause the coating to discolour later in storage or in service.

 

Thicknesses outside the recommended range may be detrimental to the properties of the coating.

 

For typical properties of the coating see below.

STORAGE

 

Stored in a clean, dry area at ambient temperature the material will not deteriorate. However, in the interest of good housekeeping, stocks should be rotated.

 

HEALTH AND SAFETY

 

Plascoat PPA 583 is supplied as a finely divided powder. Whilst there are no known health hazards associated with PPA 583, 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 certain 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 HS511, available on request.
