Laboratory Special Formulation Behsan Kar Chemi understands that no two applications are the same, and thus we offer custom formulating services. We can build a new product from the ground-up, or simply modify a formulation that already exists. Either way our staff of accomplished chemists is up to the challenge. Most products can be blended in batches as small as three drums. In addition to greases and oils we can develop and manufacture other formulas such as cleaners, degreasers products.
