Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract We report the results of studying the effect of phosphorus-containing compounds, tetraethyl-diamino-tert-butyl phosphite and diethyl phosphite, on organosilicon compositions based on polyphenylsiloxane resin. The addition of these compounds in the composition improves the dispersion of aluminum dust, wettability of the aluminum/steel substrates by the organosilicon composition, and the gloss and surface roughness of the coatings. In the compositions with the maximum disaggregation factor of the pigment particles, the gloss is enhanced by 5% and the coating roughness is decreased by 40%.
