LOCTITE® AA 3525

LOCTITE® AA 3525 is a commercial-grade, single-part acrylic adhesive engineered for high-strength, toughened structural bonding. This light-cure adhesive eliminates the need for mixing, offering immediate processing efficiency for high-volume manufacturing and assembly. It delivers exceptional structural integrity, flexibility, and moisture resistance, making it the premier choice for demanding industrial applications, including electric motor balancing.

Whether you require the 25ml bottle (IDH 234691) for precise assembly or the 1L container (IDH 234693) for automated production lines. This formula ensures a low-yellowing finish even in sunlit environments, preserving both cosmetic and structural properties over long-term exposure.

Key Features & Industrial Applications

• Multi-Substrate Bonding: Formulated specifically for high-strength adhesion across plastics, metals, glass, and ceramics.
• Electric Motor Balancing: Highly stable and resilient under dynamic stress, making it ideal for precision electric motor components.

Frequently Asked Questions

What equipment is required to cure LOCTITE AA 3525?
LOCTITE AA 3525 requires exposure to UV or visible light of sufficient intensity to achieve full cure depth. For optimal process control and rapid fixture times, industrial-grade UV Lamps are highly recommended.

Can LOCTITE AA 3525 be used on dissimilar substrates?
Yes, this commercial-grade structural adhesive is specifically toughened to handle the differing thermal expansion rates when bonding dissimilar materials, such as glass-to-metal or plastic-to-metal assemblies.
