Plural Component Materials

• What Does the Catalyst Do in the Reaction?
• Initiates Cross-linking
• Controls the Rate of the Reaction

4
Uses and Benefits

• Why are they used?
• Quality
• Environment
• Cost of Manufacturing

5
Component Names

• A Component
• Resin
• Base
• Prepolymer
• Polyol
• Paint

• B Component

6
Mix Ratio

• The recipe of the components to yield the best
  characteristics of the end product.
• Material suppliers specify by Weight Vo
  lume
• Mix ratio is the critical factor in determining
  the coatings physical characteristics.

7
Plural Component Materials

• Spray Life/Work Time
• The Period of Time Mixed Material Remains Usable
• Usable Means that the Mixed Material can be
  Applied to Achieve Acceptable Physical Properties
• Pot Life can have different meanings. Be clear
  with the material supplier.

Plural Component Materials

• Types of Plural Component Paint Materials
• Polyurethanes - Common Topcoat
• Epoxies - Common Primer

9
Plural Component Materials

• The Challenge is Maintaining Proper Ratio
• Off-Ratio Blending results in Costly Failures
• Lost Production
• Rework
• Scrap
• Warranty
• Loss of market credibility
• Monitoring and Controlling the Mix Ratio Assures
  Finished Product Quality.
