- Application Equipment
Conventional Air Spray Reduce up to 10% with Q650 if required Air Assisted Airless Reduce up to 10% with Q650 if required Airless Reduce up to 10% with Q650 if required Electrostatic Spray Some adjustments for polarity may be necessary to maximum of 2 m.ohms Brush & Roll Recommended only with Touch Up Retarder Q750 - Surface Preparation
All surfaces must be clean and free from dirt, oils, rust, flaking paint, and other contaminants. Ensure a sandblast quality of SSPC-SP6 (NACE 3) commercial blast or better and prime with a compatible epoxy primer prior to application (such as FerraPrime 105FP). Proper surface preparation will enhance the performance of the coating system.
- Application Instructions
- Thinning - Thinning is not necessary, but may facilitate flow depending on application equipment, using up to 10% total by volume. Only use the specified thinners approved by the manufacturer. Be aware that additional reduction (solvent) will increase the VOC levels of the mixed coating. Always know VOC laws for coating applications in your area and follow regulated restrictions.
- Application - Mix thoroughly before use, A to B ratio is 4:1. Combine 1 gallon “A” NexShield HS Urethane Topcoat with 1 quart “B” 80500C and mix well. Apply when surface and air temperature are between 35°F - 100°F. Ensure surface temperature is at least 5°F (3°C) above the dewpoint.
- Drying Time - See application data for typical dry times. Low temperature, high humidity, poor ventilation and thick films will slow drying. Q500 Accelerator may be added up to 0.25 fl oz per mixed gallon of NexShield to increase cure rate. Using accelerator will alter cure times.
- Clean Up - Flush mixed material from pot and lines immediately after use. Clean up paint tools or spills immediately with recommended thinner, carefully observing cautions on paint and thinner labels. Dried paint may be removed by scraping.
