Two-Component Gap Filler
A two-component silicone thermal gel (A+B, 1:1 by weight) that cures to a soft, pliable solid up to 8.0 W/m·K thermal conductivity. Designed for gap-fill and potting applications where the cured material must remain compliant to avoid stressing
Strengths
- 1:1 mix ratio by weight — straightforward dispensing line setup
- Cures to soft pliable gel — absorbs differential thermal expansion without cracking
- Wets to metal, ceramic, and most plastic substrates
- Cures at room temperature; 60–80 °C oven accelerates to 30 min
- RoHS and Halogen-Free compliant
Customization
- Conductivity grades: between 2.0 – 8.0 W/m·K post-cure
- Packaging: 1:1 dual cartridge or separate Part A / Part B containers
- Viscosity adjustment for different dispensing equipment
- Pot life extension or reduction on request

- Cure is irreversible — confirm component placement before dispensing
Frequently asked questions
What is the main function of Two-Component Gap Filler?
Two-Component Gap Filler is designed to fill small gaps between heat-generating components and heat sinks or housings, reducing interfacial thermal resistance while providing reliable electrical insulation and post-cure elastomeric shock absorption.
What is the mix ratio of Two-Component Gap Filler?
The recommended mix ratio is 1:1 for Component A and Component B.
What are the cure conditions of Two-Component Gap Filler?
Two-Component Gap Filler has a tack-free time of at least 60 minutes at 25℃, a full cure time of at least 2 hours at 25℃, and can be fully cured in at least 10 minutes at 100℃.
What packaging options are available for Two-Component Gap Filler?
Two-Component Gap Filler is available in 50ml A/B cartridges, 400ml A/B cartridges, and 20KG drum packaging.
