  • I haven’t been driving my truck a lot the last long and cold winter and I guess that’s why my batterie died. Now the battery was not even four years old and I didn’t really want to replace it already but I had to. So I decided to do something to increase the lifespan of the new battery.
    I mouted 3 12V epoxy resin solar cells on the truck bed cover. I used silicone to glew them on securely. The cells are only a few millimeters thick so I can still open the bak flip cover without damaging the cells. I installed a charging regulator right next to the new battery which keeps the current from flowing backwards and avoids an overcharging of the battery.
    The new battery that I got is a 100Amp hours car battery from Battery Industry Germany (BIG). It was the biggest battery that I could find that would fit into the spot.
    The maximum output of the cells is 0.4A. So whenever the batterie is not fully charged or for example the radio is used with the engine off the solar cells will fill the battery right back up and provide a good maintenance charge.

    this is where i bought the cells: http://www.ebay.de/itm/3x-12V-100mA-1-2W-150x70mm-Solarmodul-Solarzelle-Monokristallin-vergossen-/370704767825?pt=Bauteile&hash=item564fb9db51

    ‘-Krayden a Dow Corning Distributor presents Dow Corning CI-2001 White Reflective Silicone Coating

    - Illuminating Innovations, Dow Corning CI-2001 Highly Reflective Optical Silicone Coating

    Dow Corning CI-2001 White Reflective Coating Features and Benefits
    - Cures to a resilient highly reflective surface
    - UL flammability Classification at 3mil V0
    - Room temperature cure
    - Low viscosity enhances flow and fills in narrow gaps and spaces
    - Silicone solvent-borne resin in reduced solvent
    - Dielectric strength 620 Volts/mil
    - Excellent resistance to environmental aging
    - Used in the assembly of LED lamps / luminaires

    Dow Corning’s CI-2001 White Reflective Coating helps improve light output and efficiency of LED lamps and luminaires when it’s applied onto reflectors, mixing chambers,back light units, and PCB. Mixed with one part sprayable coating provides a homogeneous finish with better environmental resistance.
    It cures at room temperature to a tough, non-tacky surface. It can be applied by spray, flow, dip, or selective coating. Dow Corning Ci-2001 coating is designed to be sprayed in industrial paint spray equipment, standard-pressure paint spray guns, or high-volume, low-pressure spray guns. Product settling may occur during storage and shipping. You can also vigorously stir the product to re-disburse the reflective filler.Either way, the material must be mixed well and be homogeneous before
    and after you dilute it. For spraying operations,a dilution of up to 20% is recommended. If possible, select a spray gun with a least a two-step or a double-action trigger. For air guns, the optimal fluid pressure is between eight and 20 PSI. Before you begin coating,spray a horizontal test pattern on paper with the air cap in the vertical position.Hold the trigger open until the material begins to run. There should be an even distribution of the material. If not, adjust the pattern width with the spreader adjustment valve. This testing will help you determine the best distance and speed combination to achieve your best coverage and finish. As a rule of thumb, begin by testing at a distance of nine to 12 inches from the gun tip to the sample at a speed of approximately 12 inches per second. If the gun is too close,
    waves of coating material may be deposited, but if the gun is too far away, there might be gaps in the coating layer. Approximately one inch after reaching the end of the sample, reduce the pressure until only air is expelled from the gun. Maintaining your steady speed, continue the gun movement for at least five more inches. This last step should keep the gun free from accumulated coating which could cure between applications and clog the gun. For dip coating operations, the material may be used as supplied.
    Or solvent diluted if a thinner film is desired. Dow Corning CI-2001 Coating cures quickly when exposed to moisture.Keep containers tightly closed with minimal head space. Partially filled containers should be purged with dry air or other gases, such as nitrogen.
    If you are using dip tanks, these should be covered when not in use. Dow Corning CI-2001 White Reflective Coating is formulated to provide adhesion to most common substrates and materials. The tack-free and cure times can be shortened significantly by introducing mild heat up to 60 degrees Celsius and 70 percent relative humidity. you may improve adhesion by priming or with special surface treatments, such as chemical or plasma etching. A typical cure for a five mil coating is 10 minutes at room temperature, followed by 10 minutes at 60 degrees Celsius. And you should never cure a coating at temperatures above 60 degrees Celsius.
