When a drop of liquid rests on the surface of a solid, and a gas is in contact with both, the forces acting at the interfaces must balance. These forces can be.

The measured wetting tension of a specific d2578 surface can only be related d2578 acceptable ink, coating, or adhesive retention through experience. Historical Version s – view previous versions of standard. These forces can be represented by surface d2578 acting in the direction of the surfaces and it follows that: The d2578 given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
d2578 These same treating techniques have been found to increase the d2578 tension of a polyethylene or a polypropylene film surface in contact with mixtures of formamide and ethyl Cellosolve in the presence of air.
At the d2578 date, insufficient experience has been gained to state a generally acceptable level d2587 wetting tension d2578 polypropylene films for commercial flexographic printing.
This test method and the specified reagents were specifically developed d578 polyethylene and polypropylene films. Link to Active This d2578 will always route to the current Active version of the standard.
Referenced Documents purchase separately D2578 documents listed below are referenced within d2578 subject standard but are not provided as part of the standard.
It is the responsibility of 2d578 user of this standard to establish appropriate safety, health, and environmental practices and determine the d2578 of regulatory limitations prior to use. It is d2578 a fundamental property of the surface but depends on interaction between the d2578 and a particular environment.
It d2578 therefore possible to relate the wetting tension of a polyethylene or a polypropylene d2578 surface d22578 its d2578 to accept and retain inks, coatings, adhesives, etc. Wetting tension in itself is not a completely acceptable measure of ink, coating, or adhesive adhesion.
The applicability and significance for use d2578 non-polyolefin d2578 must be established by the user. It is, however, possible that some other d2578 of wetting tension may be required to indicate the acceptability of polyethylene films d2578 by other processes, or from other types of polyethylene, or intended for d25788 uses. Specific hazards statements are given in Section 8. It is possible to utilize this test method and the specified reagents for films d2578 of other polymers, but this can affect the surface energies of the gas-liquid and solid-liquid interfaces, which will d2578 the contact angle and wetting tension.
