WEICON Anti-Seize High-Tech 120 g, metal-free anti-seize assembly paste, NSF H1, -40 °C to +1400 °C
0
Description
WEICON Anti-Seize High-Tech 120 g is a metal-free anti-seize assembly paste designed to protect joints against corrosion, seizing, galling and “cold welding”. With very high temperature resistance (up to +1400 °C) and strong separating properties, it supports reliable assembly and easier disassembly of bolts, nuts and fitted parts. It is material-neutral, contains no metals and is NSF approved.
Advantages and unique features
- Metal-free formulation – helps reduce the risk of electrolytic reactions
- Long-lasting protection against corrosion, seizing and “cold welding”
- Very high temperature resistance: -40 °C to +1400 °C
- High pressure resistance (230 MPa)
- Silicone-free
- NSF approval (Nonfood Compounds Program Listed H1)
- Strong VKA performance and salt spray resistance (> 170 h)
Properties and applications
- Separation and anti-seize: for threaded and fitted joints to enable easier disassembly after high-temperature service
- Anti-corrosion protection: for parts exposed to moisture and corrosive environments
- When metal-based pastes are not desired: where metallic products may cause electrolytic reactions
- Application: apply a thin, even layer; for bolts apply to the thread base and under the bolt head for a better sealing effect
- Important: do not mix with oils or greases; the paste does not replace oil/grease lubrication

FAQ
1) What is the temperature range of WEICON Anti-Seize High-Tech?
The temperature resistance range is -40 °C to +1400 °C.
2) Does this paste contain metals?
No – it is a metal-free product, recommended where metal-based pastes may cause electrolytic reactions.
3) Can it be mixed with oils or greases?
No – the manufacturer states it must not be mixed with oils/greases and it does not replace oil/grease lubrication.
4) How should it be applied on bolts?
Apply a thin layer; for bolts, coat the thread base and the underside of the bolt head for improved sealing effect.
5) What are the key safety precautions?
It causes skin irritation (H315) and serious eye damage (H318) – wear protective gloves and eye/face protection.
