At The Battery Show North America 2019,Dow Performance Silicones has showcased new materials and capabilities for electric vehicle (EV) and battery pack designers to help manage thermal, adhesion, sealing and throughput challenges.
Dow featured its newest adhesion and conductive materials innovations: DOWSIL™ EA-4700 CV adhesive and DOWSIL™ EC-6601 electrically conductive adhesive.
Bruce Hilman, Dow’s Global Segment Leader for Transportation Electronics said that through close collaboration with the customers, the company is developing advanced new silicone technologies that address broadly relevant manufacturing objectives, such
as room-temperature-cure adhesives that reduce both cycle times and the environmental impact of energy-intensive oven curing.
Latest DOWSILTM Product Line
DOWSIL™ EA-4700 CV Adhesive
DOWSIL™ EA-4700 CV adhesive for transportation supports faster curing for increased throughput and bonds at room temperature to traditional metals and plastics used in electronics assembly.
The material provides the durable adhesion and environmental sealing to substrates used in automotive electronic modules, including:
-
Aluminum
-
Polybutylene Terephthalate (PBT)
-
Polyphenylene Sulfate (PPS)
DOWSIL™ EC-6601 Electrically Conductive Adhesive
DOWSIL™ EC-6601 electrically conductive adhesive improves shielding effectiveness and stability in high mechanical stress environments with improved flexibility.
Its unique chemistry enables engineers to use it as either a formed-in-place gasket (FIPG) or cure-in-place gasket (CIPG).
Thermal Management Materials & Battery Module Mockup
Dow also showcased its broad portfolio of thermal management materials. These products help battery pack engineers and designers to balance difficult thermal materials selection trade-offs.
The company also featured a battery module mock-up that shows liquid-dispensed silicone encapsulants, gels and foams, which, with low viscosities, are ideal for filling in and around geometrically complex battery module components.
The company also features a battery module mock-up that shows liquid-dispensed silicone encapsulants, gels and foams. These formulations have low viscosities and they are ideal for filling in and around geometrically complex battery module components to reduce the impact of stress and shock and to slow the propagation of a thermal event between individual cells.
Dow also presented an Interactive Vehicle App, a digital tool highlighting where Dow materials solutions can address specific application challenges.
