Product Overview
This two-component sag-resistant silicone potting material includes addition and condensation curing formulas. Optimized with anti-slump rheology, it solves sagging and flowing defects of ordinary potting glue on vertical, inclined and overhead electronic modules. It delivers excellent adhesion and thermal stability on PCB, CPU, PC, PMMA and various metal substrates. It effectively absorbs thermal cycling stress, protecting chips and bonding wires with low volatility and high structural strength.
Technical Specifications
As dedicated thick section circuit protection silicone, it features outstanding vertical hold ability without sagging or dripping during curing. It has low volatile content, high bonding strength and excellent resistance to ozone and chemical erosion. It maintains stable insulation, shockproof and temperature-resistant performance in extreme working conditions. Viscosity, curing hardness and operating time support full personalized customization.
Product Features & Advantages
1. Superior Anti-Sag Performance: This non slump protective encapsulation material keeps intact thick coating on vertical and overhead module surfaces.
2. Stable Vertical Encapsulation: The vertical hold module potting compound ensures uniform filling and molding for special-angle electronic structures.
3. All-Round Durable Protection: Integrates waterproof, dustproof, anti-corrosion and wide-temperature resistant functions to adapt to complex environments.
4. High Structural Stability: Firmly bonds with multiple substrates, absorbs thermal stress effectively and avoids cracking or peeling failure.
Step-by-Step Usage Process
1. Pre-Stirring: Fully stir component A to homogenize settled fillers and shake component B thoroughly before mixing.
2. Accurate Proportioning: Mix A and B components strictly by standard weight ratio to retain stable sag-resistant performance.
3. Vacuum Defoaming: Defoam mixed compound under 0.01MPa vacuum for 3 minutes for bubble-free encapsulation.
4. Standard Curing: Cure at room temperature or heating condition; full curing takes 24 hours, affected by ambient temperature and humidity.

FAQ
Q1: What is the core advantage of sag-resistant potting compound?
A: It is a non slump protective encapsulation material with excellent vertical hold performance, suitable for
special-angle module encapsulation.
Q2: Will high-temperature curing cause sagging deformation?
A: No. The optimized rheological formula maintains stable molding effect without dripping or sagging
during curing.
Q3: Does stored colloidal stratification affect anti-sag performance?
A: No. Stir evenly before use, and it can fully restore stable vertical encapsulation and thick-section
protection performance.
