ASG Chemical Bonding Process

Many factors set ASG apart from larger companies, not the least of which is our unique chemical bonding process. This proprietary system allows ASG to offer a durable, custom finish at an unprecedented price point. More importantly, the essential sound of our select tonewoods and exacting design specifications ring through in every instrument we produce. We’re often asked how we can offer such impressive graphics that equal the finishes seen on custom guitars played on stages by renowned players such as James Hetfield, Rick Nielsen, Zoltan Bathory, Buddy Guy and countless others, even though their guitars cost thousands more than the production instruments on our site.

So how do we do it, and what is it? How do we get that smooth, colorfast finish with a dimensional magnitude and shine unseen on other guitars? Is it airbrushed acrylic? Machine-applied poly-resin?  In a word: No. Our finish is a unique process using several steps, a process honed to perfection in our Fullerton shop over several years of diligent refinement. We can’t tell you every aspect of the recipe, but we can furnish a few of the technical details.

It all starts with our choice of premium tonewoods, which go through an extensive preparation process after careful screening to weed out any anomalies likely to cause defects. We spread a multi-ethyl hexylacrylate monomer, and cure our tops before the real magic begins. Then we painstakingly apply a free radical polymerized imprint to the curved instrument top, almost like tattooing ink to the skin, before introducing a sorbitol-based surfactant additive and montmorillonite application to create a synergistic nanocomposite coating.

This unusual nanocomposite, once cured, was found to be a cost-effective, durable layer that seals the dye-like subcoat to perfection. The bonding and formation of the nanocomposites have outstanding adhesion-bonding properties similar to epoxies and some silicone applications, but work in a highly coactive manner with our other content agents. Several layers of a hydrogen bonding equilibrium process involving quinone and nitroarene anion radicals and dianions create a chemically protective encapsulant coating coupled using electrochemical processes for an extraordinarily stationary electrode composition, resistant to water, oil and a wide swath of light spectra, all without resorting to industry standard tooling and cost that accompanies it. The result is an unparalleled depth, sheen and detail that lasts a lifetime. Any questions?
