How to use RTV Fluorosilicone Compounds:
LR-FL2100 liquid fluorosilicone rubber is supplied as a two-component system. Mix components A and B thoroughly in a 1:1 weight ratio, followed by vacuum deairing. The mixture will achieve full cure after 48 hours at room temperature (25°C±5°C).
Application:
LR-FL2100 is recommended for:
- Two-part RTV sealing and gasketing (FIPG) for assemblies requiring fuel/oil resistance;
- Potting / encapsulation of electrical and electronic components for elastic protection and electrical insulation in fuel/oil exposure environments;
- Sealing of connectors, cable entries, and sensor housings under temperature cycling and fluid exposure;
- Elastic gap filling and vibration damping in harsh environments across a wide temperature range;
Package &Storage:
Plastic drum packaging, A/B components each 20kg separate packaging.
Keep in cool, dry place. Avoid contact with compounds containing nitrogen, sulfur, phosphorus, and heavy metals to prevent product deterioration, shelf life is 12 months from the date of production. It is shipped as non-hazardous substance. Avoid contact with compounds containing nitrogen (N), sulfur (S), phosphorus (P), and heavy metals, as these substances may inhibit the vulcanization process or lead to incomplete curing.
