But before you apply heat, wash off all the rust penetrant
Some physical properties of solvents used as penetrants
are shown in Table 1.
Each volume covers a specific NDT method, as the new Volume 2 covers liquid penetrants
Unlike elastomerics, penetrants
do not provide a surface coating.
By incorporating these innovative adjuvants "in-can", pesticide formulators may now offer their customers all the advantages of silicone superspreaders and penetrants
require a water spray to remove the excess surface penetrant
the molecular diameters of the penetrants
determined from Fisher models.
the densities of the elastomer and the penetrants
were assumed to be equal; (2) All rubbers contained large proportions of fillers that may influence the swelling properties; (3) The precision in the molar mass assessment of the penetrants
is of the order of 10% and particularly the higher molar mass liquids have broader molar mass distributions.
Qualitatively, the methods of evaluation include visual bubble examination, visual comparison and dye penetrant
These curves are reminiscent of two-stage sorption behavior that has been noted for swelling penetrants
in glassy polymers (9-12), in which the initial stage is controlled by diffusion, and the latter stage is controlled by a slower process involving polymer relaxation.
