Magnaflux SKL-SP1 Spotcheck Penetrant Pen - 12 Pack

Spotcheck SKL-SP1 is a post emulsifiable/solvent removable, red color contrast penetrant. It exhibits outstanding penetrating characteristics, providing for maximum reliability in locating surface-open flaws and discontinuities. It can be used over the entire spectrum of industrial applications where a visible penetrant inspection system meets the requirements for surface-open flaw detection. SKL-SP1 has also been successfully used on non-porous ceramics and similar materials. Note: SKL-SP1 is not recommended for the inspection of plastic materials, as it may stain, soften or even dissolve the base material under test.

This pen is ideal for small areas or parts, and for rework inspection without the overspray mess from aerosol cans.

Coverage: 1 aerosol can (16 ounce by volume) covers about 65 square feet

SKL-SP1 may be applied by: aerosol, dipping, flowing, brushing, conventional or electrostatic spray.

Penetration/Dwell Time: The generally accepted minimum penetration time is 2 to 5 minutes. 10 minutes being adequate for most situations, although specific process specifications may require longer penetration time.

Temperature: SKL-SP1 should be used at temperatures between 40°F – 125°F. Lower temperatures thicken the penetrant and longer penetration times are necessary. High temperatures should be avoided since this can lead to the breakdown of the dye resulting in color fade.

Penetrant Removal: SKL-SP1 excess surface penetrant can be removed by either SKC-S Solvent Cleaner/Remover or ZR-10B General Purpose Hydrophilic Remover.

Recommended Developers: A developer is used to maximize the sensitivity and to provide a white contrasting background against which the red indications can be readily seen. Two types of developer can be used.

SKD-S2 and ZP-9F Solvent Developers are quick drying materials, which may be applied by spraying. The component under test must be dry before developer application.

ZP-5B Water Suspendible Developer is a developer which may be applied by dipping or spraying; after application the component must be dried before inspection.

Composition: SKL-SP1 is composed of a blend of petroleum distillates, plasticizer and an oil soluble organic red dye.
