Viscous X-NP is a high-quality sealant made of 100% silicone, formulated to provide strong adhesion on a wide range of substrates such as aluminium, glass, UPVC, wall composite panels, and polycarbonate.
It offers high elasticity and excellent resistance to UV exposure, water, and extreme temperature variations. This makes it suitable for both interior and exterior applications across construction, industrial, and repair projects.
Formulated with 100% silicone to provide a smooth, glossy, and neat sealant finish without a dull effect.
Viscous follows material movement and remains resistant to cracking or breaking during thermal expansion and contraction.
Fast drying time improves overall application efficiency.
Viscous provides strong water resistance, effectively preventing water ingress and protecting buildings from leakage.
Its lightweight texture reduces load on building materials and is safe for various applications.

1. Ensure the application area is thoroughly clean and dry. Use alcohol or a multipurpose cleaner to remove dust, dirt, and any oil residues. A wet or oily surface may reduce the adhesion performance of Viscous.
2. Apply masking tape on both sides of the gap to be filled to maintain a clean application and ensure straight sealant lines.
3. Cut the nozzle tip at an angle of approximately 45°. Attach the nozzle to the cartridge, then load it into the caulking gun.
4. Hold the caulking gun at a 45° angle and apply steady pressure on the trigger. Dispense Viscous evenly, ensuring the sealant fully penetrates and fills the gap.
5. Smooth the sealant using a gloved finger or a finishing tool in one continuous motion to press the material into the joint and create a clean surface finish.
6. Remove the masking tape immediately after smoothing. Touch up the edges if necessary for a neater result.
7. Allow the sealant to cure at room temperature. Avoid touching or exposing the applied area to water during curing. Touch-dry time is approximately 5–10 minutes at 25°C with 50% relative humidity.
