In silicone product manufacturing, achieving reliable and durable bonding between silicone and ABS (including plated ABS) is a common challenge for many engineers. The bond requires not only high strength but also excellent sealing, superior aging resistance, and strict environmental certifications. ODAKE CT747A, a flexible adhesive specifically designed for silicone products, is the ideal silicone bonding agent to meet these demanding requirements.
Why Choose ODAKE CT747A for Bonding Silicone to ABS?
ODAKE CT747A is a one-component, room-temperature curing, translucent organic silicone sealant/adhesive. After curing, it forms a soft and elastic silicone rubber body, perfectly matching the physical properties of silicone products and avoiding stress cracking caused by hardness mismatch. It is optimized for bonding silicone to ABS, PC, acrylic, and other materials, particularly suitable for applications requiring high sealing and aging resistance.
Performance Validation Based on Real Customer Testing
Take a demanding customer application bonding silicone to ABS components as an example, with the following test requirements. The performance of ODAKE CT747A was outstanding:
Excellent Sealing: The bonded area successfully withstood 0.05MPa air pressure for 12 hours with no leakage, thanks to its even application and excellent wettability, effectively filling micro-gaps.
Outstanding Aging Resistance: After 24 hours at 55°C/85% RH, the bond strength showed no degradation, proving its reliability as an aging-resistant silicone adhesive.
Superior High/Low-Temperature Tolerance: After multiple thermal shock cycles from -10°C to 50°C, the bond interface showed no cracking or delamination. This stems from its wide operating temperature range (-50°C to 200°C) and high elongation at break (≥200%).
Reliable Biocompatibility & Stability: After 24 hours immersion in artificial saliva, the bond showed no debonding, whitening, or softening, making it ideal for personal care and health-related silicone products.
Safety & Environmental Assurance: The product fully complies with international eco-certifications like REACH and ROHS, ensuring the final product is safe and non-toxic.
These results demonstrate that ODAKE CT747A is not just a silicone adhesive but a high-performance sealant and bonding agent capable of handling complex environmental challenges.
Key Performance Parameters
Flexibility & Elasticity: Shore A hardness of only 18-28A, elongation at break ≥200%, ensuring the bond can flex and stretch with the silicone product—a truly flexible adhesive.
Rapid Process Compatibility: Tack-free time 5-15 minutes, full cure 24 hours, suitable for most production line paces.
Electrical & Durability Properties: Good insulation (volume resistivity ≥1×10⁴ Ω·cm) and weather resistance, ensuring long-term stability in applications like smart wearables and small appliances.
Based on its reliable performance, ODAKE CT747A silicone adhesive is widely used in:
Smart wearable devices (e.g., watch straps, health monitoring patches)
Personal care appliances (e.g., facial cleanser brushes, massage heads)
Adult products & beauty devices
Fitness equipment silicone components
Smart home silicone seals
