It was observed that white smoke was generated during the curing reaction and volatile components were scattered.
- the cured products 1 to 10 obtained in Examples 1 to 10 and the cured product comparative products 1 to 9 of Comparative Examples 1 to 9 were subjected to a heat resistance test by the following measurement method.
- the test results are shown in Table 1.
- the 1% weight loss temperature is shown in the upper row, and the 5% weight loss temperature is shown in the lower row. It was found that the cured products 1 to 10 of the present invention have a high heat resistance temperature.
- the cured product comparison products 1 to 9 since the volatile components were scattered, the equivalence ratio balance between the bur group and the Si—H group was lost, and it was expected that only the low heat-resistant temperature appeared.
- a thin film on glass was placed in a glass container on a hot plate, heated to 350 ° C. with nitrogen gas flowing, and held for 1 hour. The heating was stopped in a nitrogen atmosphere as it was, and the film was cooled to room temperature, and the surface of the thin film was visually observed.
- the thin film on glass plate (SOG film) was immersed in the amine test solution. After immersion, the test piece was washed with ion exchange water, air-dried, and the presence or absence of cracks was determined with a microscope.
- the cured products 1 to 10 of the present invention have values of a relative dielectric constant of 2.7 to 2.9, and it was found that they are low dielectric constant compounds.
- each cured product was cured, was placed in a vacuum deposition apparatus, a high purity aluminum was deposited to a thickness of 200nm under reduced pressure of less than 10- 3 Pa, pair electrodes It was. After removal from the vapor deposition system, the charge amount at 1 kHz and 10 kHz was measured with an LCR meter 42 62A manufactured by Yokogawa Hewlett-Packard Co. to calculate the film thickness and the area force relative dielectric constant of aluminum.
- the cured products 1 to 10 obtained in Examples 1 to 10 and the cured product comparative products 1 to 9 of Comparative Examples 1 to 9 were subjected to an outgas amount test by the following measurement method.
- the test results are shown in Table 1. Thereby, it turned out that hardened
- the silicon-containing curable composition of the present invention is excellent in storage stability, transparency, handling properties, curability and the like, and further, the cured product has heat resistance, crack resistance, base resistance, optical properties, electrical properties. Further, it can be used as a curable composition having excellent physical properties such as low outgassing properties.
- display materials, optical materials, recording materials, sealing materials such as semiconductors, high-voltage insulating materials, insulation 'anti-vibration' waterproofing, moisture-proofing, spin casting, potting, dating, etc.
