Description
Chemical name: 4-Diazo diphenylamine/ formaldehyde condensate hydrogen sulfate.
CAS: 41432-19-3
Appearance: lemon yellow with pure color/ free-flowing powder.
Moisture(LOD): 7+1%
Activity(titration) :100+6%
Odor: Faint, slightly irritant.
Solubility:10 grams dissolves readily with vigorous shaking in 100ml of water at 25℃.
Particulate matter: The solution from the abole solubility test is passed though medium porosity filter paper. Typical lots will show no residue and an acceptable lot will show only a small number of specks on the filter paper.
Solution stability (after 15 days): min. 50%
Application & Care
Application: Negative working sensitizer for silk creen.
Care: Keep off the actinic light and store in a cool temperature area.
Diazo Mixing Instructions
Mixing In Aluminum Foil Packaging
1. Place bag in vertical position and tap or shake lightly to gather the diazo at the bottom of the bag.
2. Tear or cut the top of the bag (easier to cut).
3. Open pack gently to prevent diazo from escaping.
4. Pour in 50ml / 50cc / 50g of water.
5. Fold top edge of the bag over twice to seal.
6. Hold the bag closed tightly and gently agitate solution using a side to side motion to dissolve completely.
7. Pour the mixed solution / diazo into the emulsion.
8. Pour additional water (50ml / 50cc / 50g) into the bag to rinse out any residual diazo left in bag. Repeat steps 5-7.
9. Mix / Stir the emulsion until the mixed solution / diazo is fully dispersed (color should be even / uniform) .
Mixing In A Separate Container (Recommended)
1. Pour 100ml / 100cc / 100g into a container (plastic pails, cups, etc.) .
2. Gather diazo to the bottom of the bag.
3. Open packet gently to prevent diazo from escaping.
4. Gently empty the diazo out of the pack into the container.
5. Mix / Stir until diazo is fully dissolved.
6. Pour the mixed solution / diazo in the emulsion.
7. Mix / Stir the emulsion until the mixed solution / diazo is fully dispersed (color should be even / uniform) Recommended Water Amounts: SBQ Emulsions 25 ml / 25cc / 25g of water per quart (additional water may be required to fully dissolve diazo) 100ml / 100cc / 100g of water per gallon size Diazo / Dualcure Emulsions 100ml / 100cc / 100g of water per quart 400ml / 400cc/ 400g of water per gallon .
Note: Water volume is a recommendation and can be modified to the user’s liking. Goal is to fully dissolve diazo. For consistency, use the same water volume every time.
