Application process:
• Mixture obtained should be tested prior to mass production usage for every batch manufactured.
The mixture obtained should cure / harden in 5-20 mins at 170 ℃ ± 2 ℃
E.g. A copper plate with a shallow hole, with heater below may be used for the test. However, the temperature should be maintained at 170 ℃ ± 2 ℃ during the test.
• Having added the Catalyst K-1, the mixture must be used within 4hrs during summer, within 6hrs during winter.
• During manufacturing process, temperature should about 250 ℃ . If the mica sheets separators (be it steel or fiberglass sheets) are too tightly bound together, it means that too high a pressure is used or the separators need to be recoated.
• The percentage of silicones should be at 7-9% of the mica plate's weight. If the percentage is too high or too low, simply adjust usage of toluene for fine-tuning. No changes to other compositions.
• Above steps are for purely recommendations, and in no way guaranteed by our company. Actual use should be adjusted to suit the manufacturing process and requirements accordingly.
