Liquid latex is a compound often used for special effects makeup, body painting, mask making, and casting applications.
Limerick [edit]
Liquid latex is ordinarily made of 33% latex, 66% water, and less than 1% ammonia (to increase its shelf life and to control the pH of the solution). Liquid latex is sold in volumes ranging from 2 ounces to 1 gallon, and its consistency is similar to latex house paint. Its consistency can be augmented with the use of additives. For example, water can exist added to thin the latex, and Aerosil tin exist added to thicken it.[1] Cosmetic liquid latex contains approximately 0.three% ammonia, while arts and crafts and mould-making liquid latex can contain more double this corporeality, giving the latter a much stronger odour.
Liquid latex is naturally clear, and dries into a translucent amber color. Manufacturers add pigments to the product to provide opaque pigment choices of multiple colours. The colour of the paint in the jar may initially look chalky or pale, but as it dries, it develops into a rich color (for case, gray becomes blackness). Acrylic paint can be mixed with liquid latex for custom colours, but may not be suitable for utilize in cosmetic applications. In these situations, liquid makeup or food coloring tin be used.
As the latex dries, information technology becomes quite mucilaginous and volition stick to itself if accidentally folded over. Most manufacturers offer a slick spray for latex one time it is dry to remove tackiness, assuasive the movement of the model'due south limbs. Alternatively, powders can be dusted over stale liquid latex to create metal effects. 1 advantage to the tackiness of liquid latex is that it can deed as an adhesive for attaching items such as zippers. Different well-nigh other body and face paints, liquid latex is removed by peeling it off, since water does not reactivate it.

A four-ounce jar of liquid latex can typically comprehend an average human being torso. It is typically applied using a disposable sponge and takes about 5 to ten minutes to dry depending on how thick it is applied. Equally it dries, it solidifies to a rubbery consistency and in the process ends up shrinking by approximately 3%.[2]
Removing latex from skin can cause pain or pull torso hairs out, like to waxing. Even though latex is non-toxic, some people can have an allergic reaction to it. The nigh astringent of these happen immediately and are categorized every bit an immediate hypersensitivity reaction.

Mold Making [edit]
Liquid Latex is useful for molding due to its flexibility one time dried, which allows for the casting of undercut sculpture.[3] In that location are several methods for making a latex mold, each with numerous variations. Below is a full general outline of several methods. In whatever method of mold making, care must be taken to avoid air bubbles on the first layer of applied latex.
Brush Method [edit]
Commencement, the original object to exist molded (master) is cleaned and dried before beingness paced onto a not-porous substrate. Adjacent, liquid latex is painted onto the chief, leaving the bottom uncovered, but painting out around the base on the substrate. Latex must be painted on in multiple layers, allowing the latex to dry between each one. The drying procedure can be expedited with the apply of a fan or hair dryer. The number of layers applied typically ranges from 8 to twenty, though more may be necessary depending on the size of the mold. A latex mold of a chess piece 15cm in height would usually have 8 - 10 coats. Reinforcement, such equally burlap, string, or cheesecloth, may be added betwixt layers to strengthen the latex, and prevent tearing during removal from the casting.[4]
Dip Method [edit]
If your master is porous enough to draw moisture from the latex, you tin simply dip the master into the liquid latex to make your mold. Later on dipping, bubbles may class on the surface of the master. If this happens, pop the bubbles with a brush and re-dip immediately. Allow latex to dry in betwixt dips.
Removing the mold [edit]
Once the latex is completely dried, the latex mold is and so peeled off, turning the latex mold inside-out in the process. Talcum powder or soapy water should be applied to the exterior of the mold before removal, to prevent the latex from sticking to itself. Afterward popping the latex back into its original shape, you tin can and then use the mold to cast the item in your casting medium of choice.[5]
Safety [edit]
Due to the presence of Ammonium Hydroxide, liquid latex may cause pare irritation and eye irritation. The amount of Ammonium varies profoundly, and depends on the latex's intended utilise. Liquid Latex intended for mold-making may cause serious eye irritation.[half-dozen] If liquid latex gets in your optics, rinse charily with water for several minutes. Remove contact lenses, if present and easy to do, and go along rinsing.
Latex is also a mutual allergen, and may trigger an allergic reaction in some people.
