2、R - SOLIDS AND ASH CONTENT Application This method is used to determine the solids and ash content of silane adhesion promotor. Apparatus and Materials Required Porcelain Crucible With cover: 40 mm diameter and 35 mm high. Desiccator Charged with suitable desiccant. Analytical Balance Accuracy of +/
3、 - 0.1 mg. Mechanical Convection Oven Capable of maintaining a temperature of 105 +/ - 2 C. Muffle Furnace Capable of maintaining a temperature of 950 +/ - 10 C. Acetic Acid Solution 6 g of approximately 100 % acetic acid diluted to 100 mL with deionized water. Conditioning and Test Conditions All t
4、est values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/ - 2 C and 50 +/ - 5 % relative hum idity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure Determination of Solid Content: 1. Heat 3 cruc
5、ibles and covers in the muffle furnace for 30 minutes at 950 +/ - 10 C. 2. Cool the cr ucibles and covers in the desiccator, then weigh to the nearest 0.1 mg (Wa). 3. Place approximately 3 g of the sample into each crucible and weigh (include covers) to the nearest 0.1 mg (Wb). FORD LABORATORY TEST

Evaluation: Calculate the % solid as follows and report the results as the average value of the 3 samples. % solids = Wc - Wa x 100 Wb - Wa Where: Wa = initial weight of crucibles and c
