Testing of Insecticidal Paint Toxicity – VOC Matter

VOC insecticidal paint

Sample 1 (BD99)

Insecticidal Paint Toxicity VOC: The amount of the paint taken in the Aluminium dish was 50 grams. After subjecting to heating in oven, its weight recalculated. Following were the results:

Weight of Aluminium dish before heating= 50 grams

Weight of Aluminium dish before heating= 46.5 grams

% VOC = = 6.8%

Sample 2(D-50EC):

Insecticidal Paint Toxicity VOC: The amount of the paint taken in the Aluminium dish was 50 grams. After subjecting to heating in oven, its weight recalculated. Following were the results:

Weight of Aluminium dish before heating= 50 grams

Weight of Aluminium dish before heating= 44.6 grams

% VOC = = 10.8%

Sample 3(DM-50EC):

Insecticidal Paint Toxicity VOC: The amount of the paint taken in the Aluminium dish was 50 grams. After subjecting to heating in oven, its weight recalculated. Following were the results:

Weight of Aluminium dish before heating= 50 grams

Weight of Aluminium dish before heating= 43.4 grams

% VOC = = 13.2%

Blend 1(BD99 & D-50EC):

The amount of the paint taken in the Aluminium dish was 50 grams. After subjecting to heating in oven, its weight recalculated. Following were the results:

Weight of Aluminium dish before heating= 50 grams

Weight of Aluminium dish before heating= 45.1 grams

% VOC = = 9.8%

Blend 2 (BD99 & D-50EC):

The amount of the paint taken in the Aluminium dish was 50 grams. After subjecting to heating in oven, its weight recalculated. Following were the results:

Weight of Aluminium dish before heating= 50 grams

Weight of Aluminium dish before heating= 44.2 grams

% VOC = = 11.6%

Here are the results summarized in the form of graph:

pH Test

The pH test is simply performed by using digital pH meter to know the exact readings of the samples. For this purpose, each time pH meter was dipped into the prepared paint and the reading was noted when the fluctuations on the pH meter stopped. Following pH values were obtained:
