the period and the amplitude of the swings of the pendulum is measured as a function of temperature or time according to the method described by B. Hartman and G. F. Lee, Journal of Applied Polymer Science, 21 (1977) p. 1,341. The period p is related to the relative rigidity (RR...
*Pendulum hardness determined according to DIN EN ISO 1522: 2006 As can be seen from the results in Table 1 use of the clear coat compositions contemplated herein leads, in the same overall drying time, to coatings with earlier hardness and improved hardness development. Specifically the coating...
In the alicyclic alcohol sequential addition process, the time period until the whole quantity of the 4,4′-dihydroxybicyclohexyl compound represented by Formula (3) is added to the reaction system may be suitably set in consideration typically of the operational ease and reaction rate, but is ...
The polyorganosiloxane can be compounded with (meth)acryloyloxysiloxane capable of forming the unit of the formula (I-1). A methacryloyloxysilane is particularly preferred as the compound capable of forming the unit of the formula (I-1). Specific examples of the methacryloyloxysilane include β-m...
(distance between supports). All test specimens are conditioned to the measurement temperature of 0° C. over a period of from 2 to 3 hours. A test specimen is then placed without delay onto the support of a pendulum impact tester in accordance with ISO 179. The distance between the ...
