Manufacturing Process
Mixing Phase
Mix Polyurethane Prepolymer with the Silane Coupling Agent at 25°C for 20 minutes using a high-speed dispersion mixer.
Add UV Stabilizer and Antioxidant while maintaining a steady temperature of 25°C and mix for an additional 15 minutes.
Final Processing
Slowly incorporate the Clear Flow Additive while continuously stirring to prevent bubbles.
Add the Curing Agent and Solvent gradually, maintaining a homogeneous mixture.
Conduct viscosity tests to ensure it meets specifications (3000-5000 cps at 25°C).
Usage Instructions
Apply a continuous bead along the joint or seam. Allow curing for 24 hours at room temperature before exposure to outdoor elements. Use a caulking gun for precise applications.
