Starch Paste Powder

B36 is a *pre-gelatinised starch refined from regular Maize. It is a general purpose pure bookbinding paste and contains no fungicide.

To prepare, whilst vigorously stirring, add powder to cold water until required consistency is reached.

Available in:
300g packs - makes approximately 1 gallon
1.5kg packs - makes approximately 5 gallons
25kg sacks - makes approximately 62 gallons

Specification:
*Pre-gelatinised starch is starch which has been cooked and then dried in the starch factory on a drum dryer or in an extruder making the starch cold-water-soluble. Spray dryers are used to obtain dry starch sugars and low viscous pre-gelatinised starch powder. Pre-gelatinised starch is a processed carbohydrate. It does not contain gelatin and is safe for vegetarians and vegans.

Instructions or Information:
As the B36 is a water soluble paste, to some extent the amount of cold water you add to the paste powder is up to you. Most would make it up to the consistency of wallpaper paste. This is quite ‘gloopy’ and jellified. So if you turn the mixing container upside-down, the paste will stay in place. However, if you prefer using the paste wetter, then this is fine too. Just bear in mind that the paste will take longer to dry, as there is more water to evaporate away. It also depends on what you are doing:

• For paper to paper, then thicker is better
• For leather to board, slightly wetter would be better, as both leather and board are vey absorbent. In fact with leather you may want to do a first application on the leather, allow to dry before applying a second coat.
• For ‘paste-washing, then the paste can be wetter still.

It really is a matter of trial and error depending on what you are doing.
