REDGARD PU - 108
Selection and Specifications Data
GENERIC TYPE: Aliphatic Polyurethane, Part A and Part B mixed just prior to application.
GENERAL PROPERTIES: REDGARD POLYURETHANE COATING is a high build, attractive, satin finish top coat with very good resistance to splash and spillage of acids, alkalies, solvents, salts and water. It is easily applied by airless or conventional spray.
Excellent abrasion resistance
Excellent flow characteristics
- Maybe applied in a single coat directly over inorganic zinc primers
Substrates and Surfaces Preparation
These instructions are not intended to show product recommendations for specific service. They are issued as an aid determining correct surface preparation, mixing instruction and application procedure. It is assumed that the proper product recommendations service from the materials.
|SURFACE PREPARATION||Remove any oil or grease from surface to be coated with clean rags soaked in REDGARD HHB THINNER in accordance with SSPC-SP 1-82|
|STEAL||Apply over clean, dry recommended primers|
|MIXING||Mix Part A seperately, then add part B in the recommended proportions and mix thoroughly. Do not mix partial kits|
|POT LIFE||4 hours minimum @ 75°F (24°C) and less at higher temperatures. Pot life ends when coating becomes too viscous to use. Moisture contamination will shorten pot life and cause gallation|
|BRUSH||Recommended for touch up only. Use natural bristle brush applying with full strokes. Avoid rebrushing. Two coats maybe required for uniform hiding and film thickness|
|ROLLER||Use medium to long nap-roller depending on surface. Thin up to 25% by volume with REDGARD PU REDUCER for proper flow-out. Two coats may be required for uniform hiding and from thickness|
|TEMPERATURE||To Handle or Re-coat|
|40°F (4°C)||20 Hours|
|50°F (10°C)||12 Hours|
|75°F (24°C)||5 Hours|
|90°F (32°C)||1 Hour|
Use REDGARD PU REDUCER
Read and follow all caution statements on this Product Date Sheet and on the Material Safety Data Sheet for this product.
