How to Precisely Control the Mixing Ratio of AB Silicone

I. Core Issues Caused by Inaccurate AB Silicone Ratio

Even a 1–3% deviation in the AB silicone mixing ratio can directly result in product failure:

• Incomplete curing, surface tackiness, and insufficient hardness

• Bubbles, cracking, and poor adhesion

• Significant degradation of temperature resistance, waterproofing, insulation, and other performance properties

• High rework rates leading to increased costs and delayed delivery

Root Causes: Manual weighing/volume dispensing has large errors, temperature and viscosity fluctuations, and unstable material supply—making long-term precision control extremely difficult.

II. Automatic AB Glue Dispensing Machines – The Precision Mixing Solution

AB glue dispensing machines are the industrial standard solutionto inaccurate ratio issues, with key advantages:

• Independent servo-driven dual pumpsensure ratio precision up to ±0.5%–±1%

• Constant temperature control + closed-loop adjustmentoffset fluctuations in temperature and viscosity

• Supports a wide ratio range from 1:1 to 100:1 with one-click formula switching

• Equipped with static/dynamic mixing for uniform, bubble-free blending

• Features automatic alarms and anti-curing cleaning for stable mass production

Switching from manual mixing to automated dispensing eliminates ratio inaccuracies, boosts efficiency, and reduces defect rates—making it the optimal choice for silicone potting processes.
