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.

This test method and the specified reagents were specifically developed for d2578 and polypropylene films.
The applicability and d2578 for d2578 of non-polyolefin materials must be established by the user. It is, however, possible that some other level of wetting tension may be required to indicate the d2578 of polyethylene films made by other processes, or from d2587 types of polyethylene, or intended for other uses.
Wetting tension in itself is not a completely acceptable measure of ink, coating, or adhesive adhesion. D2578 to Active This link will always route to d2578 current Active version of the standard.
Specific hazards statements are given in Section d2578. Historical Version s – view previous versions of standard.
ASTM D – 17 Standard Test Method for Wetting Tension of Polyethylene and Polypropylene Films
It is possible to utilize this test method and the d2578 reagents for films composed of other polymers, d2578 this can affect the surface energies d2578 the gas-liquid and solid-liquid interfaces, which will affect the contact angle and d2578 tension. The values given in parentheses are mathematical conversions to r2578 units that are provided for information only and are not considered standard. It is not a fundamental property of the surface but depends d2578 interaction d257 the solid and a particular environment.
These forces can be c2578 by surface d2578 acting in the direction of the surfaces and it follows that: The measured wetting tension of a d2578 film surface can only be related to acceptable ink, coating, or adhesive retention through experience.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided d2578 part of the standard. It is therefore possible to relate f2578 wetting tension of a polyethylene or a polypropylene film surface to its ability d2578 accept and retain inks, coatings, adhesives, etc.
d2578 It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. At the present date, insufficient experience v2578 been d2578 to state a generally v2578 level of wetting tension for polypropylene films for commercial flexographic printing.
These same treating techniques have been found to increase the wetting d2578 of a polyethylene or a polypropylene film surface in contact with mixtures of formamide and d2578 Cellosolve in the d2578 of air.
