TYPICAL USES

Plascoat NG10 is ideal as a general coating material, being particularly suitable for domestic wirework applications.

GUIDE TO TYPICAL COATING CONDITIONS

Recommended Pretreatment:

For mild steel, ensure metal is clean by thorough degreasing and removal of mill scale.

Batch Operation:

Metal preheat temperature 300°C - 400°C, depending on metal thickness. Dip for 3-5 seconds. A post-heat cycle at 200°C may be required to develop fully the surface finish on thin items.

Automatic Coating Plant:

Pre-heat oven 360 - 400°C for 2 to 4 minutes

Dip 3 - 5 secs

Post-heat oven 200 - 220°C for 2 to 4 minutes

Water Quench Optional

The process temperatures used should only 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.

HEALTH AND SAFETY

Plascoat NG10 is supplied as a finely divided powder. Whilst there are no known health hazards associated with NG10, 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 HS101, 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.
