TASETO KEIKO CHECK Fluorescent Penetrant Inspection Materials

Product Made In Japan
Manufacturer: TASETO
Model: KEIKO CHECK

TASETO KEIKO CHECK, the fluorescent penetrant inspection material, detects any minute defects or flaws accurately.
KEIKO CHECK Inspection should be done under Black Light (ultraviolet lamp).
Three types of TASETO KEIKO CHECK, water washable, post emulsifiable, and solvent removable fluorescent types, are available.
The developer includes non-aqueous type, dry powder type, and aqueous type, and each has its advantages.

Types	Symbols	Characteristics	Applications
Water washable penetrant	N-21P	Hydrophobic type	For smooth surface
	L-2	Higher sensitivity than N-21P.	For smooth surface
	N-180P	Water based type	For low-precision inspection
High sensitivity water washable penetrant	N-2P	High fluorescent brightness. Inspection is possible without a developer.	General testing
	N-3P	Higher sensitivity than N-2P.	Precision testing
	N-4P	Higher sensitivity than N-3P.	High-precision testing
	N-5P	Higher sensitivity than N-4P.	Ultra-high precision testing
Post emulsifiable penetrant	AP-5 AP-6	For precision inspection. Use AE-56 as emulsifier. Suitable for testing fine hair cracks.	Ultra-high precision testing
Emulsifier	AE-56	Used with AP-5 or AP-6.	For post emulsifiable fluorescent Penetrant
Non-aqueous developer	FD-S	Large suction force of penetrant Quick drying.	Partial testing of large-size parts.
Dry developer	ADD-456	White fine dry powder.	For detecting very fine flaws.
Wet developer (aqueous)	ADW-456	Used by dispersing white fine powder in water.	Suit for penetrant testing equipment.

Applications

Mass-produced small parts, threads, keyways, and other acute corners, and rough surfaces.

Features

1. Good fluorescent brightness and flaw detectability.
2. Usable with a variety of developers, thus widening the range of applications.
3. N-series fluorescent penetrants have self-developing action. Developers are not needed;
however, the use of a developer enhances the flaw detectability.
4. N-21P fluorescent penetrant is optimum for decreasing the drainage cost.

How to Use
