TQC Sheen Automatic Panel Sprayers (4500N – 4700N)

Repeatable results with automatic panel sprayers

This durable automatic paint sprayer from TQC Sheen is designed to remove inconsistencies in the application of wet sprayed coating materials when applied by experienced operators using a handheld gun. It can save time in application and create a consistent set of parameters for your paint testing.  

Consistency in paint testing applications

Consistency in coating application is absolutely essential for subsequent evaluation of color, gloss, opacity, and general appearance for inks and coatings. It is also very useful for assessing the physical properties of a paint or coating, including thickness, sagging, levelling and adhesion. 

Evaluation of these properties is particularly important when applying high performance coatings such as metallic, pearlescent paints and special effect coatings. By eliminating variabilities at the application stage, it means you can attribute any discrepancies in the applied coatings to differences in formulation or processing before the application of the coating material. 

Pneumatic application: Automatic Panel Sprayers

TQC Sheen Automatic Panel Sprayers are fully pneumatic and have been developed in association with major coating manufacturers, to ensure they match real-world demand. 

It is equipped with a range of adjustments to allow you to determine the optimum settings for consistency in the application of a wide range of liquid coating materials. Subsequent sample batches can be applied using the same settings. 

Our Pneumatic Panel Sprayers also comply to the requirements of ASTM D823/A, which denotes the standard practices for producing films of uniform thickness of paint, coatings and related products on test panels. 

Panel sprayer options and models

Two models are available, namely SH0586 and SH0590. (Previously SH4500N & SH4700N models respectively) 

The SH0586 is equipped for a single spray gun* use, the SH0590 model has the facility for two spray guns. Spray guns are not included with the Sprayers and should be bought separately.  

Differences between the new models and the superseded Sheen 4500N and 4700N models 

• The models SH0586 and SH0590 are the standard Sheen 4500N and 4700N, which had a switch for 2 settings with fixed values of 40 and 50 mm lift increments. 
• The models SH0582 and SH0581 are 2 new models, which are also based on Sheen models 4500N and 4700N, however with configurable lift settings. They also have a switch, but this switch has a custom predefined Lift setting as of factory. The lift setting can be configured in steps of 10mm up to maximum of 500mm. The lower the number the more steps. The required configuration needs to be defined on the order. 
• The SH0582 model benefits customer specified panel lift increments, from 10 to 500mm. (smaller increments produces greater overspray of previous pass of the spray gun. Lift increments to be specified at the time of ordering) 

New spray panel variants

Based on the SH0586 (single gun) and SH0590 (twin gun) models, the two new variants SH5082 (single gun) & SH5081 (twin guns) are available for the customer to specify the gun lift increments from 10mm to 500mm. 

Spray panel holders

All models are supplied with magnetic panel holders as standard; an optional Vacuum Panel Holder is available for use with non-magnetic and other flat panels. This option is only available when installed from the factory. 

Setting parameters 

The sprayers offer the facility to determine the optimum atomization, coating build, flash off timing, flow/levelling, film thickness, and also gun traverse speeds and accelerated drying. 

These settings are particularly important when defining the characteristics of new formulations. 

Optimum settings

Once the optimum settings for a product have been achieved, they can be easily reproduced for quality control and further sampling, thus enabling identification of any inconsistencies in formulation or preparation.
