    HELP........anyone know how to make dilatant?

    I am looking for someone that is capable to produce a chemical called "dilatant"

    I got my own set of the formula to make dialtant but I need a chemist to help me out.

    I believe one wants to make a 'dilatant' compound, along the lines of what Dow Corning has made, a version of which became known as Silly Putty.

    Re: HELP........anyone know how to make dilatant?

    "Dilatant" appears to be just an adjective being used as a noun. Dilatancy is a rheological property. A fluid which increases viscosity as shear is increased is called "dilatant" (an adjective, not a noun). A good example of a dilatant fluid is cornstarch dispersion in water (I do not know at what concentrations).

    Beach sand as well (at least along the Gulf coast in Texas).

    maybe misunderstood from wikipedia? Quote from the article:
    ,... and then the "cornstarch" example is given.

    Re: HELP........anyone know how to make dilatant?

    No. You aren't misunderstanding Wiki. At low or slow velocity, a dilatent material (usually a suspension) will have a lower viscosity than at high velocity. The beach sand can be handled quickly and form a ball which then melts away when you stop handling it. It is actually a wonderful example that almost everyone who has made mudpies understands.

    I used to run the rheology equipment in our Division... actually I set up the laboratory and trained all of the operators. I've heard of it.....

    I just wonder what is the different between D3O ( www.d3o.com/) and dilatant compound?? Is there any commercial formula for this product??
