Formulating high quality products depend on the characteristics of your raw materials like color, acid, inhibitor, viscosity and refractive index. Consistent low color positively contributes to the appearance of the final product. The low acid value helps to stabilize the product and ensures an extended shelf life. Subsequently, the low residual acid content also allows for lower levels of inhibitor without compromising stability. Consistent viscosity delivers the desired physical characteristics while achieving the required refractive index that matches your final product. Esstech, Inc. is a reliable source that can produce materials with such strict specifications.
