Hardt bright streamer question


Recommended Posts

Hi guys...

what's the use of wheat flour in hardt bright streamer composition? Secondly why flake aluminium insted of atomized as in other tailed stars.

Posted

wheat flour is for binding, as paste or powder.

Flake aluminiums are used to help consolidation when the metal content is high flakes hold eachother better.

what kind of compositions are bound with wheat paste?what make difference binding composition with wheat paste and with dextrin.

Thank you

high charcoal/flitter comps need wheat paste to bind properly.

Wheat paste will create a rubbery patty that cuts nicely, even better results are acheived by adding dextrin to.

The paste makes a patty that won't crumble when cut and dextrin makes it harder

 

try it, you'll like it

Can wheat flour be used instead of dexrin in other compositions or even in bp?

I probably wouldn't want to use it in BP. I think it would slow it down and increase dross.

I think so too.

CMC is the best for BP

Wheat paste is not used INSTEAD of dextrin. It's used in addition to dextrin. My experience is that wheat paste gives wet strength and a cohesive mixture, while dextrin is the primary agent that gives wet strength. This is particularly helpful when dealing with streamers and mixes high in flake aluminums. It's also supposed to be helpful when dealing with compositions containing coarse materials like firefly compositions and some brocades.

 

Please make sure not to mix up wheat flour and wheat paste. They are not the same thing, and are not interchangeable. Wheat flour must be cooked into wheat paste in order to get the most out of it. Wheat flour on it's own is only mildly adhesive and probably wont confer much of a benefit.
