WATER-BASED FLUORESCENT LIQUID PENETRANT
K81B-K81B/T-K81B2
DESCRIPTION / APPLICATION(S)
Fluorescent (type 1) liquid penetrant K81B is water-washable and
emulsifier removable (Method A&D), biodegradable, water-base, with a
sensitivity level 1 (1/2 for K81B/T, 2 for K81B2), with a
flashpoint higher than 150 °C.
• Contains no oil or petroleum distillates
• Self-developing, it is possible to avoid the use of developer
• No background and low penetrant consumption due to its low viscosity
• Very low sulfur and halogen according to the Standards
• Environmentally friendly: not flammable, no toxicity and COD levels
• Conforms Standards : EN 571, ISO3452, ASTM E1209, ASTM E1417, AMS
2644, ASTM Sez.V Art.6 etc.
INSTRUCTIONS
1- Pre-cleaning: a good cleaning is essential to obtain reliable
indications and to reduce the fluorescent background. Clean the surface
by rapid evaporation solvent Elite BC1 (flammable) or by protective
detergent Elite 20, the only compatible with Elite K81B that can be used
directly in sequence without the steps of rinsing and drying before
applying product Elite K81B.
2- On the surface cleaned by Elite 20 apply a thin layer of K81B by
spraying, dipping, or brush application.
3- A 2 to 20 minute dwell time is suggested. Allow the penetrant to
drain from the part: it allows penetrant savings and improves
performance.
4- In order to remove penetrant, wash with water at ambient temperature.
Avoid washing penetrant with high water pressure or high temperatures.
Washing with water may be preceded by a pre-wash with Elite E81B
emulsifier diluted in water from 0.5 to 10%. This allows the elimination
of fluorescent background from "difficult" surfaces and a considerable
reduction of water consumption by allowing water recycling.
5- Drying: begin drying procedure immediately after the water wash; do
not allow water to stand or puddle on the part’s surface. Compressed air
is recommended to disperse and remove any surface water before placing
the part into the oven. Place part in a re-circulating oven set no
higher than 70°C, just long enough to evaporate surface moisture. Use a
heat gun to dry parts too large to fit in oven; avoid overheating.
6- Developing: K81B is self-developing, although a developer can be used.
Developing time remains mandatory according to the Standards (2 ÷ 20
minutes about).
7- Inspection: inspect part under appropriate UV light intensity.
Shelf life: 5 years from manufacturing date. Keep away from direct
sunlight.
NB: Water based composition implies that at temperatures close to 0°C
the product may become cloudy and even freeze. This does not modify its
characteristics: it is just necessary to bring the product back to the
working temperature range according to the Standards (10°C - 50°C)
before use.
