When using silane coupling agent KH-560 to treat alumina powder, what is the ratio of silane solution?

The proportion of silane solution can be adjusted according to needs, generally 20% silane and 80% solvent; The proportion of alumina added to the solution depends on the surface area of alumina. The larger the surface area, the more solution is used (the solution needs to be coated with alumina particles). The recommended ratio is 0.5-2% of solution: alumina, and the temperature usually appears when stirring, 40-50 degrees. The drying time will be very long. Generally, it takes 1-2 hours to enter the oven, and the temperature is controlled at100-10 degree, 895673768 qq. Youpu chemical industry
