Developed for testing materials that can be affected by petroleum-based penetrants, ZL-4C water-based fluorescent penetrant contains no petroleum derivatives and is harmless to materials that can be attacked by petroleum-based solvents, such as plastics. It is also safe for use on ceramics, and it can be used as a leak detector. It is always recommended that the inspection material is tested for compatibility with ZL-4C prior to use.
An ultra-high sensitivity penetrant (Level 4), ZL-56 fluorescent water-washable penetrant is safe for use on alloys in engineering and aerospace use, including aluminum, steel, nickel and titanium. ZL-56 is designed for non-porous and highly machined components. Developers recommended are ZP-4D powder, ZP-9F non-aqueous, SKD-S2 non-aqueous and ZP-5B water suspendible.
Developed for testing rough machined surfaces, ZL-60D fluorescent water-removeable penetrant is ideal for finding indications in castings, forgings, extrusions and rough surfaces.
This medium-sensitivity penetrant washes off parts quickly and easily, leaving less fluorescent background – even on rough surface – for clearer indications and better inspection reliability.
ZP-4D is a noncombustible dry powder developer for form A penetrant testing that is ideal for highly sensitive fluorescent penetrant processes. ZP-4D is applied to oven dried parts following the use of penetrants and forms a thin film on parts that enhances the visibility of ultra-fine discontinuities.
ZP-4D is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.
As a complementary developer for penetrant inspections, ZP-5B forms an opaque white coating that makes a contrasting background for indications. This white powder developer is mixed with water for use and disperses quickly to form an opaque white suspension, but must be continually agitated during use to ensure uniformity of mix as developer will settle out on standing.
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.
Por lo general, se usa para una amplia variedad de materiales de prueba, como soldaduras, fundiciones, forjas, pruebas de fugas, recipientes a presión, aeronaves, marina, construcción, mantenimiento, tuberías de petróleo, componentes de plantas de energía y trabajos de metal en general en equipos automotrices y fuera de carretera. y maquinaria agrícola.
ZP-9F figura en la lista de productos calificados QPL SAE AMS 2644.
Designed to remove excess surface penetrant, ZR-10E minimizes surface background during Method D fluorescent penetrant testing while protecting indication integrity in critical component inspections. ZR-10E provides long tank life and excellent solution consistency for dependable, long-lasting performance in a variety of applications.
