A Testament to Our Capability

"The strong relationship Dow has with SMI goes back several years to the very beginning of our Moldable Optical Silicone product line. The fit was natural. We had experience with SMI in other markets, and they're only a few miles down the road from our commercial, manufacturing, and technical centers. SMI was one of the first fabricators in the world to mold parts with DOWSIL™ Moldable Optical Silicones, helping us to grow the silicone secondary optic segment for LED lighting. What does this history mean for SMI's customers? It means they'll benefit from SMI's fabrication expertise and relationship with Dow's material experts."
