Product Description
DOWSIL™ EA-6052 Fast Low-Temp Cure Adhesive Kit is a black, flowable, two-part addition-cure silicone adhesive mixed 1:1 by weight or volume. Its temperature-controlled heat cure gives manufacturers a choice of 60 minutes at 90°C, 30 minutes at 125°C, or 10 minutes at 150°C, while a typical five-hour working time at 25°C supports dispensing and assembly operations. The mixed material can flow, fill, or self-level after dispensing and includes a UV indicator for inspection. Typical cured performance includes 4.7 MPa tensile strength, 170% elongation, Shore A 48 hardness, and 4.9 MPa unprimed lap shear to aluminum. Applications include sealing lids and housings, attaching baseplates, gasketing, and connector sealing.
Key features
- Temperature-controlled cure: Typical heat-cure schedules are 60 minutes at 90°C, 30 minutes at 125°C, or 10 minutes at 150°C.
- Two-part 1:1 system: Parts A and B are mixed 1:1 by weight or volume, with a typical five-hour working time at 25°C.
- Flowable dispensing: The mixed adhesive can flow, fill, or self-level and may be applied by manual or automated needle dispense.
- UV inspection indicator: Supports visual inspection after dispensing.
- Cured mechanical profile: Typical values include 4.7 MPa tensile strength, 170% elongation, Shore A 48 hardness, and 4.9 MPa lap shear to aluminum.
