Description

ZP-9F Product information

ZP-9F is a non-aqueous developer made of organic particles, used often in aerosol cans. It produces a fast-drying, opaque white coating and contrasting background for fluorescent and visible penetrant inspections.

It is typically used for a wide variety of testing materials such as welds, castings, forgings, leak testing, pressure vessels, aircraft, marine, construction, maintenance, petroleum pipelines, power plant components, and general metalwork in automotive, off-highway equipment and farm equipment.

Benefits of ZP-9F

• Provides excellent background contrast
• Fast drying
• Thin opaque coating masks surface blemishes
• QPL SAE AMS 2644 Qualified Product List

Increases indication visibility

• Improves indication detection by creating an optimal surface for penetrant indication formation.
• Bright white, opaque coverage blocks all underlying surface color and quickly draws penetrant to the surface for stronger, clearer indications.

Application versatility

• Can be used with a variety of Type 2 and Type 1 penetrants in many different situations without measuring or diluting.
• EN ISO 3452 conformance allows SKD-S2 to be used to inspect a wide range of parts.
• The solvent blend in SKD-S2 makes it suitable for use at low temperatures, especially around 0°C and lower, where using water would be impractical.

Faster cleaning

• Reduces inspection process time by minimising post-inspection cleaning.

Instructions for use

Before using any developer, ensure the test surface is clean, free from excess penetrant, and dry. Residue from water-based penetrants can be removed with a water spray; solvent-based penetrants by wiping with a solvent cleaner.

With visible penetrants, cracks will appear as red lines and porosity as spots. If you see a general reddish colour or pink film, that means the penetrant was not completely removed.

With fluorescent penetrants, indications will fluoresce bright yellow/green under UV light. If you see a general greenish film, that means the penetrant was not completely removed.

If left to stand, the developer particles will settle out of suspension. ZP-9F must be continually agitated/shaken during use to ensure uniformity of mix.

Apply by spraying only (dipping or brushing will cause excessive solvent action) by aerosol or conventional spray gun. Spray in thin even layers which just wet the
surface. Too wet a spray will cause excessive bleeding and running of indications; too dry a spray will result in slow indication development, as well as possible loss in overall sensitivity.

After inspection, remove developer residue by wiping with a cloth, or use a water and detergent wash.
