LOCTITE AA-3038 is a two-part acrylic adhesive specifically engineered for bonding low energy plastics without requiring surface pre-treatment. This advanced formulation delivers robust adhesion across challenging substrates. It significantly streamlines manufacturing processes. Furthermore, it enhances the durability of critical assemblies.
General Information of LOCTITE AA-3038
LOCTITE AA-3038 utilizes a two-part acrylic chemistry, comprising a clear yellow gel resin (Component A) and a viscous straw-colored liquid hardener (Component B). This system requires precise mixing, typically through a static mixer, to initiate cure. The product cures effectively at room temperature, simplifying application procedures. Its medium, thixotropic viscosity prevents material migration after dispensing, ensuring consistent bondline integrity. Consequently, this characteristic is crucial for precise application.
The formulation incorporates 0.25 mm fillers. These fillers meticulously control the bondline thickness, optimizing adhesive performance and joint strength. The thixotropic nature of LOCTITE AA-3038 reduces liquid product migration after application to the substrate. This ensures the adhesive remains precisely where applied, preventing run-off and waste. This acrylic technology offers reliable bonding solutions for demanding industrial environments.
Key Features & Technical Benefits
- No Surface Pre-treatment Required: Bonds low energy plastics like LDPE and HDPE directly, eliminating costly and time-consuming surface preparation steps.
- Two-Component Acrylic System: Ensures a reliable, consistent cure at room temperature, providing robust structural bonds.
- Thixotropic Gel Consistency: Prevents adhesive migration post-application, maintaining precise bondline geometry and reducing material waste.
- Integrated 0.25 mm Fillers: Controls bondline thickness accurately, optimizing stress distribution and maximizing bond strength.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Bonding e-coated metals (ECS) to glass fibre filled polypropylenes (PPGF).
- Adhering various low energy substrates, including LDPE and HDPE.
- Structural assembly where surface pre-treatment is impractical or undesirable.
