November 4, 2026 ALPHA HiTech SM42-1311 Mount Adhesive
ALPHA HiTech SM42-1311 is a high-performance one-component fast curable surface mount adhesive designed specifically for high-speed dispensing applications in SMT assembly lines. Manufactured by MacDermid Alpha, this advanced formulation ensures reliable component holding before wave soldering processes.
Key Features of ALPHA HiTech SM42-1311
Engineered for automated electronics manufacturing, this surface mount adhesive provides outstanding process stability and adhesion strength. The key technical benefits of ALPHA HiTech SM42-1311 include:
- Excellent Thermal Resistance: Capable of withstanding harsh thermal profiles during wave soldering operations.
- Excellent Adhesion Strength: Keeps surface-mount components securely anchored to the PCB during high-speed assembly.
- Non-Sagging Profile: Exceptional workability that prevents dot slumping and maintains consistent dot height profiles.
- Halogen-Free & RoHS Compliant: Fully halogen-free formulation strictly complying with RoHS Directive EU/2015/863 environmental standards.
Application Guidelines and Curing Profile
Adhering to proper storage, thawing, and thermal curing protocols ensures optimal performance when applying ALPHA HiTech SM42-1311:
- Storage & Thawing: Store at 1°C to 10°C in an upright position with the tip facing the bottom. Allow syringe to thaw at room temperature for 2 hours before opening the cap.
- Dispensing Guidelines: Optimized for high-speed dispensing applications under room temperature conditions. To prevent contamination, never return unused material to its original container.
- Curing Profile (Convection Oven): Achieve full property development by curing at 120°C for a minimum of 120 seconds, or at 150°C for a minimum of 80 seconds.
