1 Introduction

1.1 Overview

The SC-450 PreciseCoat Jet is a non-contact coating valve providing high-speed delivery and exceptional

volumetric control for various conformal coating fluids. The SC-450 PreciseCoat can jet conformal coating

materials between and next to components up to 15 mm. It dispenses fluid either as discrete dots or a

rapid succession of dots to form a line down to 1.5 mm wide. Please contact Technical Support for the

suitability of the SC-450 PreciseCoat Jet technology for other applications. It is fully compatible with

Select Coat Series Coating Systems.

This manual is intended primarily as a reference for trained process engineers and service technicians.

However, others unfamiliar with Select Coat applicators may also find this manual useful as a general

introduction.
