REYNOLDS RHODIUM R5
Ultra Brilliant White Brightness - World's brightest rhodium at L*91
Highest Rhodium Content - at 5 gram / 100mL. More concentrated for more rings.
​
Reynolds Rhodium is a product of SunWing Technology HK and is imported from Europe.
Reynold R5 contains the highest Rhodium content at 5 g per 100 mL compared to competitor. This translate to more concentrated and more rings plated.
​
Thicker coating, with deposits up to 1.5 µm brilliant brightness.
​
Works even at the lowest rhodium concentration of 0.3 g.
Produced ultra brilliant white bright rhodium deposit of L*91 and Yellowness Index of 6
Reynold contains brightener to aid process complex design
L* refers to lightness, evaluated according to CIELAB system (DIN5033), 100 is most bright. YI:D1925 is a Yellowness Index, the lower the value, the least yellow
MAKE UP PROCEDURE :
To make up one litre of rhodium bath,
1. Prepare 600 cc deionized / distilled water
2. Gently add 15 ml pure sulphuric acid
(Analytical Reagent grade) with stirring.
3. Gently add 40 ml Reynold R5 with stirring.
4. Top up with deionized / distilled water to one litre
mark.
