Overview
MY3070 is a high-performance industrial adhesive developed for demanding applications across multiple industries. As a structural adhesive, it forms permanent bonds between dissimilar materials, maintaining integrity under mechanical stress and environmental challenges. The adhesive belongs to the category of modified epoxy resins, combining the strength of traditional epoxies with improved flexibility. Its formulation has been optimized through proprietary technology to deliver consistent performance in both manufacturing and repair applications.
Physical and Chemical Properties
MY3070 exhibits a viscosity range of 15,000-25,000 cP at 25°C, making it suitable for both manual and automated application methods. The adhesive cures through an exothermic reaction when mixed with its designated hardener, typically reaching handling strength within 2-4 hours at room temperature. Key chemical resistance properties include stability against oils, mild acids, and alkalis, though prolonged exposure to strong solvents may degrade the bond. The cured adhesive maintains dimensional stability across its operating temperature range, with a glass transition temperature (Tg) of approximately 80°C.
Main Applications
In the automotive sector, MY3070 is extensively used for bonding structural components such as body panels, brackets, and reinforcement elements. Its vibration damping characteristics make it particularly valuable for electric vehicle battery assembly. The electronics industry employs MY3070 for potting and encapsulation of sensitive components, where its low shrinkage during curing protects delicate circuits. Aerospace applications include composite material bonding in non-critical structural areas, subject to rigorous testing and certification.
Safety and Storage
Uncured MY3070 requires careful handling as it contains potential skin sensitizers. Facilities using this adhesive should maintain proper ventilation and provide chemical-resistant gloves (nitrile or neoprene recommended) and safety goggles. Storage stability is typically 12 months from production date when kept in original, unopened containers. Once opened, the product should be used within 3 months. Partial crystallization may occur at temperatures below 5°C; this can usually be reversed by warming to 40-50°C with gentle mixing.
B2B Procurement Guide
When sourcing MY3070, industrial buyers should verify the adhesive meets relevant industry standards such as ISO 10964 for structural adhesives. Technical datasheets should specify batch-to-batch consistency metrics including viscosity tolerance and cure time parameters. For large-volume procurement (over 500kg), consider negotiating pricing based on annual commitment levels. Quality-conscious buyers should request third-party test reports validating bond strength under specific environmental conditions relevant to their application.
