AT5130-Two-part Structural Acrylic Adhesive for Low-Surface-Energy Bonding
AT5130 is a premier, solvent-free two-component acrylic-based structural adhesive specifically developed for high-performance bonding of low-surface-energy (LSE) thermoplastics. Engineered to eliminate the need for primers or complex surface pre-treatments, it provides exceptional adhesion to challenging substrates such as polypropylene (PP), polyethylene (PE), polyamide (PA), and TPO
Features and benefits
-
Primerless LSE Bonding: Superior adhesion to PP, PE, TPO, and PA without the cost and time of surface pre-treatment.
- Exceptional Durability: Provides excellent thermal stability, water resistance, and chemical resistance (including salt-water, brine, and diesel).
-
Mechanical Fastener Replacement: Replaces screws and rivets, reducing weight and preventing stress concentration in structural assemblies
-
Thixotropic Consistency: Non-sagging paste formula allows for precise application on vertical or overhead surfaces.
-
Multi-Substrate Versatility: Effectively bonds plastics to metals (Steel, Aluminum, Copper) and composite materials like FRP.
- Environmental & Safety Compliance: Solvent-free, low-odor formulation that fully complies with RoHS 2011/65/EU standards.
