VACUUM METALLIZING COATINGS - VB-4360-SP

 

VB-4360-SP HIGH HEAT VACUUM METALLIZING BASECOAT
DESCRIPTION VB-4360-SP is an industry recognized standard, in High Heat Resistant Clear VM Basecoats. Among its attributes, VB-4360-SP offers adhesion to most high heat resistant substrates including Nylon, GTX, PC, BMC, PET, Polyarylate, Aluminum, Steel, Zinc Die Cast, Ultem and Amodel PPA. At optimum cure, VB-4360-SP develops exceptional hardness and provides iridescent free performance through 500 F. This Metallizing Basecoat exhibits excellent specularity and optical properties, and cures to a clear, transparent film. VB-4360-SP is suggested for use on high intensity Automotive and general purpose lighting applications, where the ultimate in adhesion and performance are required.

OTHER INFORMATION DOT Classification: Flammable Liquid (FL) HMIS Rating: 2-3-0 H-F-R HMIS RATING KEY H = Health F = Fire R = Reactivity 0 = Minimal Hazard 1 = Slight Hazard 2 = Moderate Hazard 3 = Serious Hazard 4 = Severe Hazard REDUCTION Apply as is, without reduction for spray. Reduce 2:1 or as much as 3:1 with Acetone or Butyl Acetate for dipping applications. Reduce 3:1 or as much as 4:1 with Butyl Acetate for application by flow coat method. APPLICATION Method: Apply by Conventional or HVLP Spray, Dip and Flow Coating application. CURE CYCLE Flash off 15 to 30 minutes, followed by a 90 minute Cure at 250 degrees F. For shorter baking schedules where higher temperatures permit, bake at 300 - 325 degrees F. for 60 minutes. Can be cured for shorter durations, at temperatures up to 500 degrees F. SPECIAL NOTES Due to the unique nature of this coating, VB-4360-SP can be cured at significantly lower temperatures than the assemblies in-service operating temperature may require. Please contact your Pearl Paint representative to learn more about VB-4360-SP and other thermally resistant Vacuum Metallizing Coatings. STORAGE Store in tightly sealed containers, at ambient temperatures. Protect from moisture, evaporation and foreign materials. Process ability of this product can be adversely affected by evaporation and contamination. SHELF LIFE 12 months, provided materials are kept in sealed original containers under specified conditions. Storage beyond this period can produce higher viscosities. AVAILABILITY VB-4360-SP is available in 5 and 55 gallon epoxy phenolic lined steel containers. Please contact Pearl Paints for ordering information.
