ABLESTIK CE 3511PHV
Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses
Main features
- Extended Dispensing Pot Life
- No-Bleed Conductive Placement
- Fast Hot-Plate Cure Option
Product Description
LOCTITE ABLESTIK CE 3511PHV is a one-part, silver-filled, electrically conductive epoxy adhesive for circuit assembly. The silver paste is designed for dispensing, has no bleed, and provides a pot life greater than 14 days at 18 to 25 deg C. Heat-cure options range from 60 minutes at 100 deg C to a hot-plate cure of 60 seconds or less at 180 to 190 deg C, although lower-temperature curing reduces electrical conductivity. After cure at 180 deg C, the typical volume resistivity is 5 x 10^-4 ohm cm. The cured adhesive has a typical glass transition temperature of 100 deg C and tensile lap shear strength of 12 N/mm^2.
Key features
- Long dispensing window: A pot life greater than 14 days at 18 to 25 deg C supports extended dispensing operations.
- No-bleed silver paste: The one-part paste is designed for dispensing and limits resin bleed during component placement.
- Flexible heat-cure schedule: Multiple oven and hot-plate options balance cure time and temperature, with lower-temperature cure reducing conductivity.
Applications
Applications include circuit assembly, die attach, component bonding, and attachment of heat-sensitive components.
