GRAFFITI PROOFER® NANO-BASE
The next generation of nanotechnological non-stick protective resin is here. The GPA-400 is a non-stick coating with leading-edge durability, hardness and chemical resistance. GPA-400 is single component, water-clear, UV stable, heat stable and the product is dry to the touch in 2 hours . The GPA-400’s resin is a hybrid consisting of a patented methyl extended siloxane diol that is coupled with a unique nano-ceramic particulate that together provide both leading-edge durability and an astonishing high slip coefficient.
The GPA-400 does not allow paint, graffiti, permanent marker, stickers, gum, road tar, cement and other markings or environmental contaminants to bond to the dry film. This product is environmentally friendly, non-reactive, VOC, AQMD and CARB compliant.
Check with SEI for a certified applicator in your area.
GPA-400 exceeded the performance requirements
for ASTM D6578 Graffiti Resistance Test.
The GPA-400 is applied in 1 coat - recommended thickness is 14-150 Microns dry depending on application and substrate. The GPA-400 covers more square footage than any anti-graffiti coating on the market today.
SURFACE PREPARATION :
Apply the coating only when the surface temperature is more than 5F or 3C above the dew point temperature of the surrounding air and relative humidity is below 85%, in order to prevent moisture condensation on the surface. Always apply test area before proceeding with entire application. The surface is to be clean and free of any foreign matter. Product must be applied to a dry surface. Always apply to a test area before proceeding with entire application. Surface must be corrosion free at the molecular level although sanding may be sufficient a chemical cleaning and corrosion removal is recommended. Any existing corrosion may continue to propagate when coated that can lead to a coating failure in due course.
Concrete: Concrete temperature must be at least 60F (16C) during the coating application. Blast areas to be coated using sharp, angular abrasive grit. All surfaces are to be vacuumed or blown-down with oil-free, moisture-free air. Use steel shot of SAE 230-330 to prepare surface using a “Blastrac®” or similar device. The operator of this device should be experienced; concrete can be damaged by holding in one localized for extended times or using shot of improper size. The concrete surface shall be finished with a rough edge, free of chemical or environmental contamination, dry, clean of loose debris and of adequate surface strength. Neutralize acidic and alkaline surfaces, remove grease, standing oil, old coatings, sealants and dirt. SCS-002 Sp Sealer Prime is an approved sealer to be used as a primer for the GPA-400.
