Plastisol is the result of thin vinyl resin particles dispersed in a specific oil. A liquid plastisol coating is applied to various components to ensure the impartation of specific qualities. In Grand Rapids, finishing companies often use this technique on metal substrates to meet not only functional specifications but also aesthetic ones. One method of achieving optimal results is dip coating.
Dipping is one of the oldest methods employed with vinyl dispersions. Plastisol dipping or dip coating is the dipping into or immersion of the substrate surface of a metal component in a liquid plastisol. This deposits a layer or skin of the plastisol on it. The part is then withdrawn from the liquid. Each action is set at a specified rate to ensure the right thickness of the coating.
Dip coating is capable of imbuing the metal substrate with a number of benefits – all intended to improve the overall quality and capabilities of the component. Among the numerous benefits derived from the process are:
- Corrosion and chemical (most alkalines and acids)resistance
- Thermal and electrical insulation
- Added resilience and durability
- Color and texture
- Versatility for selecting the thickness of the film or coating
- UV Stability
- Vibration and sound dampening
- Improved handling
- Enhanced aesthetic qualities
Finishers also find this method easy to use on geometrically complex and intricate parts. It easily coats the hard-to-reach nooks, corners, angles, and crannies. It provides protection while smoothing over the edges. All accomplished without interfering with or even affecting the overall functionality of the part.
Liquid Plastisol Dip Coating
The advantages inherent in employing dip coating are ideal for meeting and even exceeding the demands of certain applications. In Grand Rapids, finishers utilize this method for diverse applications. From tools to medical instruments, dip coating in liquid plastisol provides such diverse parts with several required and desirable qualities.
