Post-Application Treatment for Polyurethane Sealant Curation: Touch Dry Time: This refers to the time it takes for a skin to form on the sealant surface, typically ranging from tens of minutes to several hours (affected…
How to Use Polyurethane Sealant Loading and Cutting the Nozzle: Load the sealant tube or barrel into the gun. Use a nozzle cutter to create an opening at approximately a 45-degree angle (or a flat…
Preparing Polyurethane Sealant Before Using Surface Cleaning (Critical!): Removing Dirt: Use a wire brush, sandpaper, or scraper to thoroughly remove dust, oil, rust, old paint, release agent, water stains, frost, loose particles, and any other…
Curing and Maintenance of Neutral Silicone Sealant Touch-free Time: A skin (non-tacky) will form on the surface of the sealant, typically within 30 minutes to 2 hours after application (subject to temperature, humidity, and adhesive…
How to Apply Sealant Cut the Hose Seal: Use a utility knife or scissors to cut the seal evenly along the top of the collar on the hose opening. Install and Cut the Nozzle: Tighten…
Neutral Silicone Sealant Neutral silicone sealant is a versatile, high-performance sealing material. Due to its neutral (non-corrosive) properties after curing, excellent elasticity, strong weather resistance, and mildew resistance, it is widely used for bonding and…
Nail Free Glue Usage Instructions Surface Preparation Clean surfaces with alcohol or detergent to remove oil, dust, and moisture. Ensure surfaces are dry, smooth, and stable. Critical: Poor cleaning reduces adhesion by up to 70%!…
Storage Conditions for Nail-Free Adhesive Cores Temperature Control Ideal range: 5°C to 25°C (avoid high temperatures or freezing). High temperature risk: Temperatures above 40°C may accelerate hardening or fluidization (e.g., in a car or on…
Nail-Free Adhesive Application Instructions Surface Cleaning Use alcohol or detergent to thoroughly remove oil, dust, and water stains from the adhesive surface. Ensure the surface is dry, flat, and free of loose particles. Key Point:…
How to Store Polyurethane Sealant Temperature Control: Optimal Range: The ideal storage temperature is 5°C to 25°C (41°F to 77°F). Avoid High Temperatures: Temperatures above 30°C (86°F) significantly accelerate chemical reactions, resulting in: Increased viscosity…
Polyurethane sealant formulations vary depending on the application. Construction adhesives: They prioritize weather resistance and migration resistance. Polyether or polyester polyol base polymers with excellent UV and hydrolysis resistance are selected. Filler selection balances performance…
