Density (Specific Gravity) Cups
The Density of a coating should remain constant from batch to batch. Also known as
Density(Specific Gravity)
Cups. Specific Gravity Cups are used to determine the specific weight per unit volume
of a liquid at a given
temperature.
A stainless steel precision instrument for determining the specific weight of paints and
similar products.
A tolerance of 0.1% is guaranteed. Testing is carried out in accordance with ISO at
23±2℃.
This instrument consists of a cylindrical container and cover with a hole for exhaust of
excess liquid for any
excess Paint(or Ink)to be removed when the cup cover is pressing tightly.
By doing so, will also ensure that no air bubbles(or pockets of air)are being trapped.
It is in according with DIN 53217,ISO 2811,and BS 3900 A19. And each density cup
comes with Calibration Certificate.
Procedure
-Weight cleaned density cup empty and record weight
-Temper density cup and test liquid(20℃±0.5℃;68°F±1.0°F)
-Fill density cup
-Put cover on without tilting
-Avoid air bubbles
-Remove overflowing liquid carefully with absorbent cloth
-Weight filled density cup
-calculate density
