Permabond UV640 thicker viscosity general purpose impact resistant clear UV glue

PERMABOND UV640 is a single part, fast setting, and UV curable adhesive designed specifically for bonding plastics. This material has excellent adhesion to a variety of plastics including polycarbonate. Permabond UV640 has very high shear strength, elongation and impact resistance making it ideal for applications that require substrates with different coefficients of thermal expansion. Features & Benefits Cure on demand High shear strength Fast curing with low-power lamps 100% solids, no solvents Excellent adhesion to plastics Physical Properties of Uncured Adhesive Chemical Composition Methacrylate ester Viscosity @ 25°C 20rpm: 3,000-5,000 mPa.s (cP)2.5rpm: 12,000-25,000 mPa.s (cP) Specific Gravity 1.1 Performance Characteristics UV Curing Wavelength 365 - 420 nm UV Curing Time (by strength of light) Low power 4mW/cm² battery lamp: 10 secsLED 100mW/cm² lamp: 4 secsUV light guide 30W/cm²: 2 sec Tensile Strength 1900psi (13 N/mm^2)
