Polyurea Coatings

RamShield CPS-300

Two-Component, 100% Solids, Zero VOC, Fast-Set Aromatic Silicone Polyurea Spray Elastomer

Overview

Ram Shield CPS-300 is a two-component, 100% solids, zero VOC, 1:1, fast-set aromatic silicone polyurea spray elastomer system. Its silicone-modified structure gives superior chemical and heat resistance compared to traditional polyurea systems. Although aromatic, Ram Shield CPS-300 exhibits reduced oxidation when exposed to UV/sunlight, greatly reducing gloss loss. It is resistant to algae and marine growth with excellent chemical and heat resistance.

Key Features

Fast Set

Gel time of 5–7 seconds enables rapid return to service, minimizing downtime across aerospace, industrial, and containment applications.

Good Gloss Retention

Silicone-modified aromatic chemistry greatly reduces UV oxidation and gloss loss compared to standard aromatic polyureas, maintaining appearance over time.

High Chemical Resistance

Superior chemical resistance for food processing plants, primary and secondary containment, and tank linings exposed to aggressive process chemicals.

High Elongation

325 ± 20% elongation accommodates substrate movement and thermal cycling without cracking or delamination.

High Film Build

Applied at any desired thickness horizontally, vertically, or overhead — theoretical coverage of 1 gallon per 1,600 sq ft at 1 mil.

High Heat Resistance

Silicone-modified structure maintains coating integrity under elevated temperature conditions in industrial manufacturing and mining environments.

Low Temperature Application

Can be applied in cold conditions, extending the usable season and reducing scheduling constraints on outdoor and industrial projects.

Typical Applications

  • Aerospace / aviation
  • Food processing plants
  • Industrial manufacturing
  • Mining and agriculture
  • Primary containment
  • Secondary containment
  • Tank linings
