November 9, 2026 ALPHA HT-130DL Surface Mount Adhesive
ALPHA HT-130DL is a one-component, intermediate-temperature, fast heat-curable surface mount adhesive designed for high-speed dispensing and screen printing applications. Developed by MacDermid Alpha, this epoxy-based red paste provides excellent productivity in wave-soldering processes. Electronics manufacturers rely on ALPHA HT-130DL for securing surface-mount components accurately on printed circuit board (PCB) assemblies prior to wave soldering.
Key Features and Benefits of ALPHA HT-130DL
This high-performance epoxy surface mount adhesive offers process stability and excellent workability for modern circuit assembly lines:
- Fast Heat Curing: Cures quickly at intermediate temperatures to maximize line productivity.
- Excellent Thermal Resistance: Maintains structural integrity and high bond strength during wave soldering thermal spikes.
- Non-Sagging Profile: Features a high thixotropic index (> 4.0) to maintain crisp dot profiles and prevent slumping.
- Excellent Workability: Formulated for stable performance in both high-speed automated dispensing and screen printing operations.
- One-Component Formulation: Supplied as a ready-to-use red paste in various syringe packaging options.
Processing Guidelines and Curing Conditions
Applying ALPHA HT-130DL on assembly lines allows operators to maintain high throughput and consistent dot geometry. The material uncured features a viscosity of 500 to 600 Poise (Malcom PC-10A, 30 rpm @ 25 °C), a pot life of 7 days at 25 °C, and a shelf life of 6 months when stored at 1 to 10 °C. Full property development is achieved in a convection oven using recommended curing profiles, such as 120 seconds at 120 °C or 80 seconds at 150 °C.
