FAQs
What is SYLGARD 184 Silicone Curing Agent used for?
This curing agent is part of the two-component SYLGARD 184 silicone encapsulant system. When mixed with the base at a 10:1 ratio, it produces a flexible, durable encapsulant used to protect electronic assemblies such as LEDs, sensors, transformers, power supplies, and high-voltage components.
How does the curing process work?
The material can cure at room temperature or be accelerated with heat. Typical cure times include 48 hours at 25 °C or as fast as 10–35 minutes at elevated temperatures between 100–150 °C. This flexibility allows manufacturers to match curing speed to production requirements and thermal limits of components.
What performance advantages does the cured SYLGARD 184 material offer?
The encapsulant provides strong dielectric properties, flame resistance, and mechanical flexibility. With a dielectric strength of around 19 kV/mm, it protects sensitive circuits, resists environmental stress, and withstands service temperatures from –45 °C to 200 °C. Its clarity is useful for optoelectronic assemblies like LED modules.
What are the mixing and handling requirements?
The curing agent must be mixed thoroughly with SYLGARD 184 base at a 10:1 ratio. Once mixed, the material has a working time of about 1.5 hours at room temperature. Proper mixing, degassing, and clean dispensing equipment help ensure consistent curing and optimal electrical and mechanical performance.
What packaging and shipping details should users know?
This product is supplied as a clear curing agent in a 20.4 kg pail and typically ships within 1–2 business days. It is intended for industrial and electronic assembly use. As with all silicone materials, users should follow standard storage, handling, and safety guidelines recommended by the manufacturer.
