Contact angles with water and methylene iodide
were then measured and the dispersion and polar components of solid surface tension were calculated (see ASTM D7490 for details).
More significantly, chrome diopsides in particular would have been lost due to the use of undiluted methylene iodide
at a specific gravity of 3.
It was synthesized by first preparing a large batch of iodoform which was then reduced to methylene iodide
Cyclopropyl bromosilane was prepared for the first time by cyclizing trimethoxy vinyl silane with methylene iodide
using the Simmons-Smith reaction.
into tetrabromoethane and than dilute methylene iodide
15 Table 3--Wate and Methylene Iodide Contact Angles with Various Weathering Cycles (Measured in Degrees) Xenon Arc As is incl.
The data in Table 3 shows water and methylene iodide contact angle measurements with six different panels (different basecoat and cleareoat compositions).
The present investigation took this change into account when calculating the dispersion and polar components of the surface free energy from water and methylene iodide contact angles.
3] treatment on three polymer surfaces--PMMA, polycarbonate, and poly(tetrafluo-roethylene) (PTFE)--by measuring contact angles of water and methylene iodide as a function of irradiation time.
A microsyringe was used to place either a water dro or a methylene iodide drop on the polymer surface with sufficient volume to provide a base of more than 0.
The two liquids selected were water and methylene iodide (C[H.
3 and Table 1 were measured using methylene iodide.
