1Measured with Brookfield viscometer HBT-DV3 +, spindle/chamber SC4-14/6R, at 25±1℃
2Take a slide glass and measure its weight, then use a fixture to scratch paste on it, put it into dry box after curing. Measure its weight after 16 hours and put it into temp & humid chamber. After 20 hours, take it out and measure its weight after drying. Calculate the ratio of weight change.
Advantages
Low surface roughness
Excellent anti-sulfurization - used in thick film resistors
Great acid resistance - applied to metal plate resistors
