AT3925M 500g Adhesives and Sealants

Viscosity 36,000, 180,000 mPas; Bending Adhesion Strength >114, >128 kgf/cm²; UV Curing Conditions 100 mW/cm², 2 min; Curing Shrinkage Rate 0.5%, 0.9%; Tg +195, +233 °C; Thermal Expansion Coefficient 18, 20 ppm/°CNTT Advanced Technology Corporation’s high-precision optical adhesives allow easy fixation of optical components with sub-micron accuracy. Based on epoxy, these high-precision optical adhesives are available with low viscosity of 36,000 mPas (AT3916P) or with high viscosity of 180,000 mPas (AT3862P). Both adhesives show minimal position changes due to curing time and temperature.Shrinkage rate during curing is very low for this series of high-precision optical adhesives, and the thermal expansion coefficient is small. Using ultraviolet (UV) ray curing makes alignment easy.NTT Advanced Technology Corporation’s series of high-precision adhesives show excellent durability: Even after a high-temperature process at +260 °C, the adhesives’ bonding strength does not change. And no peeling occurred after 200 cycles in a simplified heat cycle test.In order to achieve high reliability, a product must clear the tests conducted by the users themselves. If you have had even just a bit of dissatisfaction in precision or durability results in the past, please put NTT Advanced Technology Corporation’s high-precision adhesives to the test.In case you need any consulting regarding issues related to adhesion, please contact the AMS Technologies optical adhesives experts to discuss the detailed challenges of your application.Key Features:Low Shrinkage Rate During Curing: 0.5% (AT3862P), 0.9% (AT3916P)Low Thermal Expansion Coefficient: <20 ppm/°CUltraviolet (UV) Curing for Easy AlignmentExcellent Durability: No Change in Bonding Strength After +260 °C High-temperature Process, No Peeling After 200 Heat Test CyclesViscosity: 36,000, 180,000 mPasBending Adhesion Strength: >114, >128 kgf/cm²UV Curing Conditions: 100 mW/cm², 2 minGlass Transition Temperature Tg: +195, +233 °CApplications: High-precision Fixation of Optical Components With Sub-micron Accuracy
