Loctite SI 5710 2K 400 ml formerly Loctite 5700 transparent two-component polyaddition silicone for potting and sealing, lighting production
0
Description
LOCTITE SI 5710 400ML is an ultra-clear two-component silicone for potting that cures at room temperature. The product features low viscosity, low shrinkage and no release of by-products, making it suitable for precise optical and electronic applications. It is designed for potting and coating components in the lighting, electrical and optical industries, such as LED lenses, lighting profiles and optical sensors.
Advantages and unique features
- Ultra-clear silicone for potting
- Two-component 1:1 system
- Low viscosity for easier application
- Room temperature cure
- Cure can be accelerated with heat
- No release of by-products
- Low shrinkage during cure
- Non-corrosive
- High transparency and good light transmission
Properties and applications
- For optical potting: the product is suitable for applications requiring high transparency, such as potting LED lenses and modules.
- For the lighting industry: it can be used for lighting profiles, LED components and other systems where material transparency is important.
- For electronics and electrical applications: it is suitable for potting and protecting selected electrical and electronic components.
- For optical sensors: low viscosity and transparency support applications in precise optical parts.
- For coating processes: the product can also be used in coating processes requiring a colourless transparent material.
- Safe curing process: polyaddition technology limits the formation of by-products, which is important in sensitive technical applications.
