Columbian TecTank utilizes proprietary premium coating technology that provides maximum corrosion resistance, abrasion resistance and encourages smooth material flow. Our experience has led to continuous technology and process improvements. The result is the finest epoxy coating available in the dry bulk tank industry. The OptiBond™ coating process is derived from years of in-field experience and performance data.*
Stage 1: Parts are degreased and rinsed Precisely controlled hot air drying and pre-heating
Stage 2: Parts surfaces are blasted with engineered grit material Rugged 3-D surface topography is created for better powder coating acceptance A high velocity air curtain removes residual particulate
Stage 1: Parts are powder coated in our proprietary electrostatic booth with precision environmental controls Parts are cured at controlled temperature to maximize the cross-link bonding
Stage 2: Uniquely engineered polyurethane topcoat is applied for UV protection on exterior surfaces Sheets are cured at controlled temperature yielding the final product
Quality Control Parts are subjected to a rigorous quality control evaluation with high voltage defect testing procedure. This will identify any holidays, inclusions and thin areas in the coating. No other company has a higher quality control standard than Columbian TecTank.
