Dowsil 9189 is a flowable viscosity, fast tack free conformal coating. It has a UL 94 V-0 flammability rating and it has no added solvents. It can be considered for uses that require flame resistance. This innovative material is pigmented to hinder component identification and it will cure to a soft, low-stress elastomer. The main applications this product is well suited for are PDP module assembly and parts for fixing on circuit boards.
Dowsil SE 9189 RTV is a one part polydimethylsiloxane adhesive. The viscosity of this product is 23300 Cp and it has a 97.6 % Non-Volatile Content. At a temperature of 25 degrees Celsius, it will become tack-free in approximately 8 minutes. Dow 9189 may be applied by using an automated or manual needle. An effective temperature range for the silicone elastomer is -45 to 200 degrees Celsius for extended periods of time. Any temperature higher or lower may change the behavior of the material and applications can become complex requiring more consideration.
Dowsil SE 9189 is a room temperature cure material in an environment with 30 to 80 percent relative humidity. Mild heat below 60 degrees Celsius may be applied to accelerate the curing process. When exposed to vapor or liquid fuel or solvent, the product is only capable of handling a splash or intermittent exposure. The performance will be altered if there is continuous exposure to solvents and fuel. Dow SE 9189 will provide unprimed adhesion to a variety of substrates including ceramics, reactive metals, laminates, resins, plastics, and glass. Good adhesion cannot be expected on non-reactive plastics or non-reactive metals.
It is of high importance to comprehend the proper handling, usable life, and storage of Dowsil SE 9189. Products should be kept tightly sealed with airspace minimized. Shelf life and temperatures that this product should be stored at will be listed on the label. All surfaces need to be thoroughly cleaned or decreased to attain the best results. This product has not been tested nor has it been deemed suitable for pharmaceutical or medical uses.
