- Applications
Applications include automotive, tooling, architectural flexible moldings, prototype, Special FX, coatings and any application where rapid cure, high resiliency, firm rubber part is required. Parts can be easily stained with either oil or water based paints.
- Mixing & Curing Instructions
Measure out proper amounts of components, 1 part A to every 4 parts B, ensuring B component has been premixed prior to blending components together. Once blended, pour into silicone RTV mold and allow part to cure, 25-45 minutes, depending on thickness of part, temperature of materials and mold. If part is highly detailed, work material into the mold surface for best results. Parts can be easily stained with oil or water based paints. **Material will release from Silicone RTV mold surface, but release agent is suggested to pro-long mold life. The technique of applying ER 2300 spray mold release onto mold followed by a light dusting of mold with talc or like powder will help improve overall mold life.

Storage & Handling
- Storage
Storage RU 280 A/B is sensitive to cooler weather under 75°F and can begin crystallizing and solidifying. If material becomes lumpy and grainy due to cold weather, reheating material to 125° to 150°F will bring material back to original viscosity. Electric drum or pail heater will need to be used to avoid material problems. Call Technical support for further information.
