Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. [1] The colloid is coloured usually either wine red (for spherical particles less than 100 nm ) or blue-purple (for larger spherical particles or nanorods ). [ 2 ]
Liquid Latex intended for mold-making may cause serious eye irritation. [5] If liquid latex gets in your eyes, rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do, and continue rinsing. Latex is also a common allergen, and may trigger an allergic reaction in some people.
Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...
To create foam latex, a liquid latex base is mixed with various additives and whipped into a foam, then poured or injected into a mold and baked in an oven to cure.The main components of foam latex are the latex base, a foaming agent (to help it whip into a froth), a gelling agent (to convert the liquid foam into a gel), and a curing agent (to turn the gelled foam latex into a solid when baked).
The same paragraph also exempted "gold coins having recognized special value to collectors of rare and unusual coins", which protected recognized gold coin collections from legal seizure.

Ternary plot of different colors of Ag–Au–Cu alloys [1]. Colored gold is the name given to any gold that has been treated using techniques to change its natural color. Pure gold is slightly reddish yellow in color, [2] but colored gold can come in a variety of different colors by alloying it with different elements.
The resins for water-based paints are polyvinyl acetate latex, methyl methacrylate or acrylic resin. The resins for solvent-based paints are linseed or soya oils and alkyd resins. The pigments and resins are mixed with water for water-based paints and solvents for solvent-based paints so that they can be applied onto the road surface.
