Product Specification

Pfund Cryptometer


The Pfund Cryptometer measures the hiding power of paints and pigments quickly and accurately. Using a small 3-5ml sample of wet paint, both the hiding power in square feet per gallon and the minimum wet film thickness required for complete hiding can be determined within minutes.
The Pfund Cryptometer is invaluable for production control of paints and pigments and for assuring that shipments conform to specifications for wet hiding power. It is also used together with the Pfund Film Gage during application of paints to insure adequate and uniform hiding power at the lowest possible cost.

Quick, accurate wet hiding power measurements of paints and pigments.
Determines coating thickness needed for complete hiding.
Determines area of coverage per gallon with complete hiding.
 
Applications


Manufacturing control and testing
Cost reduction through close control of coating thickness
Testing incoming shipment for conformity with wet hiding power specification

The cryptometer operates by forming a wedge-shaped film of paint between two optically ground and finished glass plates - a graduated opaque base plate and a transparent top plate. The plates are separated at a fixed angle. When the top plate is moved back and forth, a line of demarcation on the base plate alternately appears and disappears when the paint film is of sufficient thickness to produce complete hiding of the base plate. The graduation in mm at that point of the base plate is converted to hiding power sq. ft./gal.) and thickness (mils) by an accompanying chart. Chart calculations are based upon the tangent of the angle separating the plates and the length of the paint film in mm at the point where complete hiding is produced.
The Black and White Cryptometer tests paints and pigments of all colors, including all of the chromatic colors and the blacks, whites and grays. The base plate of this model has two graduated sections of opaque glass - a black section for testing of paints or pigments having a reflection factor of greater than 70%, and a white section for darker paints and pigments. Two top plates are furnished - one having a wedge constant of .007 for paints of lesser opacity and one with a .002 wedge constant for paints of greater opacity.
