Junbond weatherproof silicone sealant is a one-part, neutral and moisture cure, medium modulus silicone sealant that provides durable, pliable, watertight joints and offers outstanding adhesion without priming to most non-porous substrates.
With its unique weather-resistant formula, it possesses a balanced adhesive strength and very high recovery, making it ideal to withstand adverse weather conditions in common installations including moisture, movement, sheer, and de-flection, heat and cold resistant, aging resistant, UV resistant .
It is easily gunnable in all weather conditions from -20 to 120 degrees F. Because our weatherproofing silicone caulking requires no mixing and a smaller joint ratio, it is an economical, high-performance alternative to other comparable sealants with a ±40 percent movement capability.
Feature
* 1. One component, easy to use;
* 2. Neutral cure RTV silicone sealant, cure at room temperature;
* 3. Ease of application ready to use as supplied
* 4. Excellent rheology, low string upon gunning
* 5. Ideal for expansion, connection, perimeter and other movement joints
* 6. Excellent weather ability, virtually unaffected by sunlight, rain, snow, ozone
* 7. Extension/compression movement capability of up to ±50 percent of the original joint width
* 8. Excellent unprimed adhesion to a wide variety of construction materials and building components
* 9. Suitable for use uncoated glass, galvanized steel, masonry and other porous and nonporous substrates
