Introduction 1
1 Introduction
1.1 Overview
The Select Coat SC-100 Series Circulating High-Speed Film Coaters provide non-atomized, selective
application of conformal coating materials. Coating is applied in a film rather than the atomized spray
produced by conventional airless spray guns. The SC-100 Series Film Coater easily integrates with
Asymtek's Century and Select Coat Series Conformal Coating Systems. Coating programs are designed
and the SC-100 Series coaters are operated with Asymtek's Easy Coat for Windows software.
This section covers the following topics:
•Models
•Specifications
•Dimensions
1.2 Models
There are two models available:

SC-104HS High Speed Film Coater 0-90°None
SC-105HS High Speed Film Coater 0-360°0-30°
Both models are based on the standard SC-100HS Film Coater.
