As you guys may have heard, after JerryRigEverthing got his hands on the LG flagship and did what most couldn’t even imagine doing, a controversy came into being. The all new LG G5 was tortured with scratches, burnt with a lighter and then a bend test was carried out. The scratch test suggested that LG G5’s aluminum chassis is in fact coated with a thin layer of plastic. Alternatively, LG themselves claimed that the ‘plastic’ layer is actually a thick paint coat which helps hide the antenna bands without disrupting their function.
After LG was asked for explanation, the following is what they said in reply:
What you’re seeing there is primer, not a plastic cover. As you know, primer is used to get paint to bond to aluminum, which is what we used for the G5’s body. The aluminum alloy we sourced is known as LM201b (patent pending) and was developed at the Korea Institute of Industrial Technology for use in automobiles and aircraft. LM201b, unlike the aluminum used in other smartphones, is diecast unibody which makes it very sturdy while still maintaining lightweight properties. We figured out a way to integrate the antenna bands into the aluminum seamlessly so you can’t feel the lines and covered the LM201b with primer and paint using a process called microdizing which means that tiny particles of metal are infused in the coating and bonded to the aluminum. I think it’s incorrect to say that a product isn’t all metal if paint is involved. That’s like saying cars and airplanes aren’t metal because they’re also painted. For the record, even metal that’s anodized will scratch off. Our process may be different but it achieved what we were aiming for, which is a smooth, seamless metal finish that’s durable and lightweight. We weren’t interested in doing what has already been done. When did this become a bad thing?
Apparently, the alleged ‘plastic’ layer was in fact a thick layer of primer, covered with paint coats. This particular process allowed LG to effectively hide the antenna strips while giving the flagship a rather warmer and softer feel as compared to the standard feel of the metal features in various other smartphones.
