A certain minimum degree of cure is necessary prior to topcoating. As relative humidity and temperature vary during the day, so does the rate of cure.

Mark a by mm 6- by 1-in. The primer was separately applied to d452 test panels at two different dry? Specific hazard statements are given in Section 6. Separate test panels corresponding to each coating thickness category were scored after a 6-h cure period and a h cure period. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

As relative humidity and temperature vary xstm the day, so does the asstm of cure.

The MEK resistance of some twocomponent ethyl silicate zinc-rich primers has been shown to correlate well with the cure of the primer as determined by diffuse re? Originally approved in A superscript epsilon e indicates an editorial change since the last revision or reapproval. It has been shown that the degree of cure of ethyl silicate zinc-rich primers can be measured by the chemical changes occurring using diffuse reflectance infrared spectroscopy.

The Society for Protective Coatings, 40 24th St. If the former, record the number of rubs when the substrate is exposed.

Reagents and Materials 5. Rate the results in accordance with Table 1. Performance ratings and general statistical information have been in Table X1.
