- 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.
