Bare Paint is a nontoxic, water based, water soluble, electrically conductive paint. Bare Paint adheres to a wide variety of substrates and is easily removed with water. Bare Paint is black in color and can be over-painted with any material compatible with a water-based paint. Please see the Bare Paint MSDS for precautionary information. Advantages Electrically conductive Nontoxic Water-soluble Works with low voltage DC power sources (see Power Sources p.2) Powers small devices Makes a unique microcontoller interface Can be used as a potentiometer Compatible with many standard printing processes Typical Properties Color: Black Viscosity: Highly viscous and shear sensitive Density: 1.16 g/ml Surface Resistivity: 55 /Sq 50 microns. More information on p.3 & 4 Vehicle: Water-based Shelf Life Unopened: 6 Months Drying Temperature: Bare Paint should be allowed to dry at room temperature. Drying time can be reduced by placing Bare Paint under a warm lamp or other low intensity heat source. 1www.bareconductive.com +44(0)2034325385 TheOldT rumanBrewery,91Brick Lane, LondonE16QL Bare Paint Technical Data Sheet Application Tips: Bare Paint is a unique material that can be applied in many different ways, from a paintbrush to common printing processes like screen-printing. To achieve consistent electrical performance it is best to apply Bare Paint in an even layer. If youre interested in screen printing Bare Paint, it is best to use a textile-type screen in order to achieve a generous layer thickness. We tend to use a 43T screen.

Power Sources: Bare Paint is intended for use with low voltage DC power sources and has not been tested with sources exceeding 12VDC. Higher voltages are not recommended. Substrates: Bare Paint is a water-based paint and it acts much like other paints you might be familiar with. Bare Paint adheres well to wood, paper products, some plastics, corks, textiles and metal. Hydrophobic materials such as glass and some plastics will exhibit poor adhesion, though this can be improved by roughing the surface with sandpaper or similar. Drying Tips: Bare Paint is fast drying at room temperature. This material dries rather than cures and gives off no fumes during the drying process. Drying time can be moderately reduced by placing the material near a low intensity heat source such as an incandescent lamp. Subjecting Bare Paint to a high temperature environment will negatively affect both physical and electrical performance. Flexibility: Bare Paint is somewhat flexible, but this flexibility depends on two factors, the layer thickness and choice of substrate. Regardless of substrate, a consistently thin layer of paint creates the most flexible circuitry. Areas of paint with wide variation in thickness tend to produce fracturing. Substrates which are flexible, but not stretchy (such as paper) work better than materials like Lycra which stretch in multiple dimensions. Cold Soldering: Bare Paint works well as a cold solder joint. Whether used to solder a surface mount or through-hole component onto a circuit board, or to adhere a component to a piece of paper, this material is strong and almost infinitely repairable. This unique property means that components can be harvested from projects, cleaned and reused. 2
