Coating Equipment

Flat spray unit

A spraying unit for flat substrates of varying dimensions up to 600 mm x 600 mm is available at the Centre. The sample table has a maximum displacement of 2000 mm. A variety of coating parameters, such as the transverse and lateral speeds of the spraying nozzles along with the table speed can be controlled to obtain coatings of desired quality. The unit is attached to a drying oven for baking the coatings prepared.

Spray coating line

A chain type coating line equipped with 95 spindles for coating of symmetrical components has been installed and commissioned. The unit is capable of coating up to 900 components per hour and the conveyor speed can vary from 1 to 15 parts per min. The coated components can be heated / dried in an adjoining IR chamber. The dimensions of a typical component that can be handled are 200 mm height and 150 mm diameter.

Spin coater

Two desk top spin coating units are available for carrying out experiments at the lab scale. The largest sample that can be handled for spin coating would be a wafer of dimensions 200 mm x 200 mm.

Dip coater

A table-top dip coater, is available for carrying out lab-scale experiments on 100 mm square substrates of up to 5 mm thickness. Variable withdrawal speed allows control over film characteristics such as thickness and uniformity. Angle dependant dip coater-can take up 1 m x 1 m substrates and can be tilted up to an angle of 15 degrees.
