Product Description
CT-E3006 is a two-component epoxy potting compound. Component A is a viscous liquid mainly composed of epoxy resin and functional fillers, while Component B is a transparent modified amine curing agent.
The product offers good flowability and can be applied manually or automatically using a dispensing machine. After curing, it provides high bonding strength to various substrates, including stainless steel, aluminum alloys, PBT, ABS and other materials.
Product Features
Moderate viscosity and excellent flowability: Suitable for both manual potting and automatic dispensing applications.
Room-temperature and heat curing: Can be cured at room temperature or by heating. Low exothermic heat during curing helps prevent damage to individual capacitors.
High bonding strength: Provides excellent adhesion to stainless steel, aluminum alloys, PBT, ABS and other substrates.
Excellent water resistance: After 1,000 hours of 85°C/85% RH testing (85/85 test), the product shows only minor degradation in physical properties such as tensile strength and shear strength.
Excellent resistance to thermal shock: Performs well under temperature cycling from -40°C to 105°C. No cracking or deformation is observed after 1,000 hours of high- and low-temperature thermal shock testing.
Excellent dielectric properties: High volume resistivity and dielectric breakdown strength, providing excellent resistance to electrical tracking and leakage.
Applications
CT-E3006 is primarily designed for waterproof sealing and protection of electronic components, including supercapacitors and capacitors.
Packaging
30 kg/pail: Component A: 24 kg/pail; Component B: 6 kg/pail
Storage and Transportation
1. Store in a cool, dry and dark place at temperatures below 25°C. Keep the container tightly sealed.
2. This product is non-flammable and non-explosive and can be transported as general chemical goods. During transportation, protect the product from direct sunlight, compression and impact to prevent leakage.
3. Shelf life: 6 months under recommended storage conditions.
