What Is LSR (Liquid Silicone Rubber)?
Liquid Silicone Rubber (LSR) is a two-part, platinum-cured silicone material. It’s known for its high purity, thermal stability, and flexibility.
In coating applications, LSR offers low viscosity, making it easy to spread thinly and evenly.

Why LSR Is Ideal for Coating Applications
LSR is increasingly used in industries requiring non-stick, biocompatible, or chemical-resistant surfaces.
Whether it’s food-grade conveyor belts, medical film, or electronics insulation, LSR delivers consistent coating performance with excellent adhesion to various substrates.
Standard vs Food-Grade vs Medical-Grade LSR Costs
| LSR Grade | Typical Cost (USD/kg) | Applications |
|---|---|---|
| Standard | $8–$15 | Industrial coatings |
| Food-Grade | $15–$25 | Packaging, conveyors |
| Medical-Grade | $30–$45 | IV bags, implants |

5 Key Benefits of LSR in Coating Applications
1. Superior Surface Smoothness
LSR levels out evenly, eliminating bubbles and streaks. This is crucial in optics and electronics coatings.
2. High-Temperature Resistance
LSR withstands up to +200°C, perfect for industrial processing environments.
3. Biocompatibility for Medical Use
Medical-grade LSR is USP Class VI tested, ensuring safe patient contact. Ideal for wound dressings and surgical films.
4. Excellent Release Properties
Coated rollers or trays release products cleanly — no sticking, no tearing.
5. Long-Term Durability
LSR coatings resist UV, ozone, and harsh cleaners. Great for clean rooms and food prep environments.
