• Durability: Formulated to withstand extreme weather conditions, this hybrid sealant maintains its flexibility and integrity without cracking or splitting, even through multiple heat and cold cycles.
• Eco-Friendly: The sealant is solvent-free, isocyanate-free, and phthalate-free, contributing to a healthier environment. Additionally, it has low VOC content and low odor, making it suitable for both indoor and outdoor use.
• Paintability: Adseal 1940 becomes tack-free within 10 to 30 minutes and is ready to paint after 30 minutes, allowing for efficient project timelines.

Installation Tips:

1. Surface Preparation: Ensure all surfaces are clean, dry, and free from contaminants such as oil, dust, or old sealant. Proper surface cleaning is crucial for a durable assembly or caulking.
2. Application Conditions: The sealant can be applied in temperatures as low as -17°C, providing flexibility for various climatic conditions.
3. Joint Design: Leave a 5 mm (3/16 in.) gap wherever siding butts against trim or other materials to allow for expansion. Use J-mould or sealant to fill the gap. ​
4. Tooling: After applying the sealant, shape the bead using appropriate tooling before skin formation. This can be facilitated with a solution of 5% clear dishwashing liquid and water to achieve a smooth finish. 
5. Painting: Once the sealant has cured (typically after 30 minutes), it can be painted to match the surrounding materials, enhancing the overall appearance.
