Product Introduction of 3M Scotch-Weld Epoxy Adhesive DP100LH Plus
3M Scotch-Weld Epoxy Adhesive DP100LH Plus LH is a fast-setting, two-part epoxy adhesive with a 1:1 mix ratio. It is unique among fast-setting mercaptan-cured epoxies, as it combines high shear strength with good peel performance. This adhesive delivers a strong, permanent bond even under vibration and impact, making it ideal for demanding applications.
With a low halogen formulation, this epoxy adhesive is particularly well-suited for bonding electronic devices. It effectively bonds a wide range of substrates including metals, ceramics, glass, wood, and many plastics. Its low viscosity allows for easy dispensing, self-leveling, and makes it highly effective for filleting and potting applications. It features a two to four-minute work life, allowing for slight repositioning, and reaches handling strength in about 20 minutes. Full cure is achieved in 48 hours at 72°F (22°C).
When using a Duo-Pak (DP) size adhesive, users can rely on 3M dispensing equipment for accurate and convenient metering, mixing, and dispensing. The adhesive offers excellent mechanical performance and is ideal for applications in electronics, transportation, specialty vehicles, electrical products, general industrial use, sporting goods, construction, and consumer goods.
