Medium solids polyester/amino coatings, exterior durability, resistance to chalking and chemical resistance. PolylureŽ1500 is a medium solids polyester/amino coatings system for aluminum extrusions. This system is designed to meet the application and performance demands of the residential aluminum window and door market. Coatings in this system are field-proven, exterior quality finishes. They provide the exterior durability, resistance to chalking and chemical resistance demanded by this market. PolylureŽ1500 coatings are an excellent alternative to acrylic/melamine offering higher solids than acrylics, while still providing the solvents necessary for efficient use of thermal oxidizers. PolylureŽ1500 coatings do not exhibit the tacky overspray associated with high solids polyesters.
All exterior components of aluminum windows and doors that will lend themselves to a factory applied oven baked finish can be coated with the PolylureŽ1500 system. This system can be custom designed to meet the color, gloss, application and cure requirements of most manufacturers of these products.
PolylureŽ1500 coatings are designed for spray application. They can be custom designed for application by manual non-electrostatic, manual electrostatic and high speed rotary atomizers such as disks and bells. They are formulated for application to aluminum that has been properly cleaned and pretreated in accordance with technical specifications from Valspar. Long-life durability and performance are achieved by applying 0.8 to 1.2 mils of PolylureŽ1500 topcoat. For special applications, PolylureŽ1500 may be applied at higher film builds.
PolylureŽ1500 coatings exhibit stain resistance and require minimal maintenance. Surface residue is generally removed with conventional cleaning solutions and/or mild detergents. Minor scratches in the field may be touched up with acrylic modified air dry enamels or two package urethane enamels matched to the same color and gloss.
PolylureŽ1500 coatings are available in a wide spectrum of standard colors. Special colors are also available from Valspar.
