George Koch Sons has repeatedly advanced and refined liquid coating technology to enhance coating performance, respond to environmental issues, and meet the needs of our customers for high uptime performance and low life cycle costs. Today, our liquid finishing systems are used alone or in combination with electrocoat and powder coat to meet stringent quality, cost, operating, and emission requirements.

KOCH is among the pioneers in liquid finishing systems, and we continue to work with customers around the world who first purchased a KOCH finishing system in the 1930’s and 1940’s.  Liquid coating has undergone tremendous change and refinement since then. George Koch Sons has contributed to that change and refinement, and we now use liquid coating alone or in combination with electrocoating and powder coating, in a wide range of applications, to help our customers meet stringent quality, cost, operating, and emission requirements.

Liquid coating is the oldest and, for many products, still the best available finishing technology. A combination of new environmentally friendly coating formulations and the development of whole new classes of complex and/or heat- sensitive products has led to continued refinement and use of liquid coating technology.

Liquid coating is widely used for automotive and other products requiring a smooth, mirror-like finish. It is widely used in finishing operations that require fast, frequent color changes. It is also widely used for application of UV-curable, waterborne, and plural component coating materials on plastics and wood. It is often the most practical choice for heat-sensitive parts, including some plastics and many parts produced by and for the electronics industry.

Liquid coating is often the most practical choice for complex parts whose size and geometry make electro-coat or powder coating and curing excessively expensive. Our high-efficiency down-draft water wash and side/down-draft paint system booths provide clean, quiet working environments. They are automotive approved, capture 99.9% of all particulates, and can be installed at floor level. Our patented recirculating air systems minimize exhaust air volume and monitor the air stream to ensure safe operating conditions. Side-draft paint spray booths can be completely enclosed with the addition of a supply plenum.
