As motor designs become more compact and power-dense, insulation systems are under constant pressure from heat, speed, and mechanical stress. For OEMs and manufacturers, the question is no longer whether insulation matters—but how to choose the right one.
The CenvarSLT Product Series is designed to make that choice easier.
Developed specifically for trickle impregnation, CenvarSLT solventless resins help ensure reliable insulation performance where it matters most—inside the winding.
Why OEMs Prefer Trickle Impregnation (When Done Right)
Trickle impregnation is efficient and production-friendly—but only when the resin:
- Penetrates deeply into winding gaps
- Bonds strongly to conductors and insulation materials
- Withstands continuous thermal stress
- Cures consistently without brittleness
The CenvarSLT Series is formulated to support all of the above, helping manufacturers avoid insulation-related failures later in the equipment’s life.
What the CenvarSLT Series Delivers?
Across the range, CenvarSLT resins offer:
- Excellent electrical insulation properties
- High bond strength, retained even at elevated temperatures
- Thermal endurance up to Class F (155°C) and Class H (180°C)
- Controlled viscosity, ideal for trickle impregnation
- Solventless formulations for cleaner processing and repeatable results
But different applications need different balances of rigidity, flexibility, and thermal margin—which is why the series includes multiple grades.

This table is often where OEMs immediately identify which product aligns with their design philosophy—and where meaningful technical discussions begin.
Where CenvarSLT Fits Best?
The CenvarSLT Product Series is widely used in:
- Electric motors and generators
- High-speed rotating armatures
- Stators and rotors
- Trickle impregnation lines
- Applications with continuous thermal and electrical load
Whether you’re scaling production or refining a new motor design, choosing the right resin can significantly impact reliability, efficiency, and service life.
Built for Manufacturing Reality
CenvarSLT resins are not just lab-tested—they are production-proven. OEMs value the series for its:
- Predictable curing behavior
- Stable processing characteristics
- Consistent batch-to-batch performance
This translates to less rework, fewer failures, and better long-term performance in the field.
Let’s Discuss Your Application
Every motor has its own operating profile—speed, temperature, load, and environment. The right insulation solution comes from matching these realities with the right resin grade.
If you are an OEM, motor manufacturer, generator builder, or insulation system designer, the CenvarSLT Product Series offers a reliable starting point—and a knowledgeable technical team behind it.
