Intelligent Controls for a Repeatable, Defect-Free Process.

This is a common myth that is no longer true. While you cannot directly charge water, modern electrostatic spraying equipment for water-based paints works through a method called isolation. The entire fluid handling system—the pump, hoses, and the gun itself—is isolated from electrical ground. The system then charges the entire paint supply to a high negative voltage. As the paint is atomized, the charged droplets are drawn to the grounded part just like a solvent-based system. TIMS COATING can provide expertly designed electrostatic spraying equipment that allows you to get the high transfer efficiency of electrostatics with the environmental benefits of water-based coatings.

Runs and sags are defects caused by applying too much paint in one area, causing it to succumb to gravity before it can set. This is a common problem that can be solved with properly set up spraying equipment. The primary cause is moving the spray gun too slowly across the part or holding it too close. Another cause is having the fluid flow rate set too high for the speed of application. An automated or robotic spraying equipment system from TIMS COATING is the ultimate solution. By programming the exact speed, distance, and flow rate, we can engineer a repeatable process where runs and sags are physically eliminated from the equation.

The nozzle tip is a small but incredibly important component of your spraying equipment. Choosing the right one is critical for a good finish. Nozzle tips are identified by a three-digit number, like "517". The first digit ("5") when multiplied by two gives you the spray fan width at 12 inches away (a 10-inch fan). The last two digits ("17") indicate the orifice size in thousandths of an inch (0.017"). You should choose a fan width that is appropriate for the size of the part you are spraying. You should choose an orifice size based on the viscosity of the material you are spraying—thicker materials like primers require a larger orifice, while thinner materials like stains require a smaller one.

A "paint kitchen" is the common industry term for the fluid handling room or area that supports your spraying equipment. It is an essential, climate-controlled space where paints are stored, mixed, quality-checked, and pumped to the spray booth. A professional paint kitchen from TIMS COATING includes agitators to keep the paint homogenous, viscosity control cups for quality checks, fluid heaters to maintain a consistent temperature (which affects viscosity), and high-quality pumps and regulators to deliver the paint to the guns at a precise, unwavering pressure. Without a well-managed paint kitchen, it is impossible to achieve a consistent, high-quality finish on the production line.
