30-01 K Laboratory Control Coater

INTRODUCTION

The K Control Coater widely used for the application of paints, varnishes, adhesives, liquid printing inks and many other surface coatings to produce quick, accurate and repeatable samples. These may then be used for quality control and presentation purposes, R& D and computer colour matching data etc. These are elements vital to a company’s success in the modern world.

Multiple coatings in one operation for comparison purposes
Standard coating speeds infinitely variable between 2 and 15m/min

Meter Bar Coating

Meter bars provide the simplest method of applying accurate, repeatable layers of surface coatings on to most substrates. A meter bar is produced by winding precision drawn stainless steel wire on to a stainless steel rod resulting in a pattern of identically shaped grooves. These grooves then precisely control the wet film thickness. Close wound bars will produce coating thickness from 4 to 120µm. Higher coating weights up to 500µm can be obtained using spirally wound bars. A three-part Melinex/foam/rubber coating bed is supplied as standard. Vacuum, magnetic, heated and glass beds are also available, as detailed on the back.

GAP APPLICATORS

Micrometer Adjustable Applicator

This applicator incorporates an adjustable spreading blade with micrometers to accurately set the substrate/blade gap from 0 - 10mm in 10µm increments, providing a most versatile tool. It gives a coating width of 100mm and produces a wet film thickness equal to the gap setting.

Bird Applicator

Precision ground all over, this stainless steel applicator provides a coating width of 100 mm and is available with gap sizes of 25, 50, 75, 100, 150 or 200µm. The Bird applicator produces a wet film thickness equal to half of the gap size.

Cube Film Applicator

Made of precision ground stainless steel, the cube film applicator provides a coating width of 41 mm. Each applicator is supplied with two gap sizes: 50 and 100µm or 150 and 200µm. This applicator produces a wet film thickness equal to half of the gap size.

4-Sided Applicator

This device enables the user to coat four separate film thicknesses with a single applicator. Providing a coating width of 60mm, the 4-sided applicator is supplied with gap sizes of 30, 60, 90 and 120µm. It produces a wet film thickness equal to half of the gap size.

SPECIAL PURPOSE COATING BEDS

Specialised coating beds are available to ensure the best possible results for particular applications. Each is suggested for different types of substrate.

Vacuum Bed

TYPE A. Recommended when coating on to a delicate or stretchy substance such as aluminium foil or polythene This is a rubber faced bed connected to a vacuum pump which holds the material perfectly flat. Vacuum is applied from the edges of the substrate only.

TYPE B. A smooth aluminium faced bed with vacuum applied via multiple holes over the entire substrate surface. This is suitable for more rigid substances, and especially recommended when coating on to paint charts with gap applicators.

Magnetic Bed - C

For use when coating on to magnetic substrates (such as tin plate) to ensure a flat surface. Permanent magnets are used and are operated by an on/off key.

Headed Bed - D

For use when applying coatings which require heating (such as hot melts). The bed has a smooth aluminium face which can be heated up to 200°C and is set by a digital temperature controller.

Glass Bed (Not Illustrated)

This provides a perfectly flat surface which is very easily cleaned. It is especially recommended for gap applicators which provide a hard surface.
