Typical Performance Properties
- Silicone Durability – Silicone rubber shows outstanding long-term resistance to natural weathering once cured, including: UV radiation, rain, snow, and extreme temperatures, with minute changes to elasticity
- Versatile Application – RTV52 is a liquid applied silicone material (one-part) and can be applied by brush, roller, or spray. No mixing of material is required.
- Ease of Use – Material has a low viscosity, allowing for easy spray application with most commercial grade spray equipment. Material will adhere to high pitches, parapets, vertical walls, and other abnormal surfaces due to its high static viscosity (until it reaches full cure).
- Ample Work Life – Material has long work life, permitting time for treatments, including application of granules.
- Accelerated Cure Rate – Quickly reaches weather resistant properties.
- Low Temperature Storage – Storing material in unheated spaces during cooler months is recommended. Do not store in location where risk of material freezing is possible.
