Description
DESCRIPTION
KEY #471 is a two component, ultra high solids, aliphatic polyaspartic polyurea designed to provide high gloss, UV light stable (non-yellowing), high temperature resistance and chemical resistant protection as a high performance industrial maintenance coating. KEY #471 is a superior, new generation resin exhibiting fast cure time and excellent stain resistance. KEY #471 has very low odor and can be applied indoors in occupied areas. KEY #471 can be used as a clear or pigmented high gloss finish coating on various Key Resin Systems.
KEY ADVANTAGES
• Rapid set time (recoat in 6 hours)
• Excellent abrasion resistance
• Chemical and stain resistance
• Hot tire stain resistant
• Excellent UV light resistance
• Low odor for use in occupied areas
• Meets USDA requirements
• High temperature resistance to 300°F
• High gloss
KEY CONSIDERATIONS
• Substrate temperature must be a minimum of 35°F
• Substrate must be free of dirt, waxes, curing agents and other foreign materials
• Do not apply over damp or wet substrates
• 15-18 minute working time; relative humidity levels higher than 50% RH will further decrease working time
• May be thinned up to 10% with MEK, ethyl acetate, or Oxsol 100
• Only pre-tint material that will be used the same day; color will darken over time
COLOR SELECTION
KEY #471 is available in Clear only, and may be tinted on the jobsite using Key Universal Color Packs (UNVCP) or Polyaspartic Color Packs (PCP) available in Key Resin Standard Colors available in Key Resin Standard Colors or approved custom colors with minimum quantity requirements and possible increased cost.
COVERAGE KEY
#471 is typically spread at 125-250 ft2 /gallon to yield 6-12 mils. Up to 16 mils is possible in one application but will exhibit a longer cure time to develop full hardness required for heavy traffic. Do not apply >16 mils.
