If a compound is cured
under a sufficient pressure for a long enough time, many times porosity can be avoided (ref.
All areas of the core were cured
and several cores were produced.
Based upon the totality of the evidence, the Appellate Term properly found that the violation of the tenancy (by reason of the continuing objectionable animal behavior) had not been truly cured
based on the sparse bubble count at 14 min, we projected that the control part would be fully cured
at about 14.
These material are usually molded in a closed system (with or without pressure) and may be cured
at room or elevated temperatures.
Upon completion of the building process the build platform is raised, and the partially cured
and uncured sand is removed from the machine.
materials exhibit high deflection temperatures, excellent chemical resistance, and good retention of mechanical properties at elevated temperatures.
systems (hotbox, warmbox and shell) are those in which the binder is mixed with the sand and catalyst, and blown into a heated corebox or against a pattern to produce the core or mold.
The products include Chemlok 8114 for bonding Vamac, bisphenol curing FKM, polyacrylates, ethylene acrylic and peroxide cured
EPDM elastomers; Chemlok 8115 for bonding sulfur cured
NBR and Vamac elastomers; Chemlok 8116 for bonding peroxide curing compounds such as silicone, EPDM, FKM and HNBR elastomers; and Chemlok 8117 for bonding peroxide curing compounds such as silicones, EPDM, FKM and HNBR, as well as bisphenol compounds and Vamac elastomers.
Tg for urethane cured
with KR 44 is 468 F versus 241 F for one cured
In addition to carbon, oxygen and hydrogen, these cores contain small amounts of sulfur after they are cured
Use of these synergistic systems can be demonstrated in both mineral and carbon black filled compounds, cured
with conventional sulfur, low sulfur, sulfur-donor or peroxide systems.
Electron curing at ambient temperatures has reduced the stresses in unidirectional composites by at least 75%, compared with an equivalent composite heat cured
at 302 F.
Cores could then be blown and gas cured
on the same machine.
Various authorities worldwide have already mentioned LEDs to be the ultimate light source for activating light cured
materials in the future.
