Is transparent nail-free adhesive less susceptible to corrosion than conventional nail-free adhesive? There’s no essential difference in corrosion resistance between transparent nail-free adhesive and conventional nail-free adhesive (such as white or beige). The key difference…
Storage Methods for Nail-Free Adhesive The storage quality of nail-free adhesive directly impacts its subsequent performance (such as bond strength and curing speed). Improper storage can easily lead to drying, delamination, and deterioration. The following…
The Difference Between Winter and Summer Formulas of Nail-Free Adhesive Winter Formula (Low Temperature, Low Humidity Environment: 0-15°C) The core issues in winter are slow curing due to low temperatures, high viscosity (difficult application), and…

Key Considerations for MS Sealant Substrate Compatibility Testing: When first using on a specific substrate (such as aluminum-plastic panel, ABS plastic, or marble), apply a small amount of sealant to a hidden area. After curing…
How to use MS sealant Core Steps: 4-Step Standard Procedure Step 1: Surface Preparation (Critical! Directly Affects Adhesion) The sealant’s effective adhesion relies on a clean, dry, and impurity-free substrate surface. The following steps should…
How to use MS sealant MS sealant (silane-modified polyether sealant) is a high-performance sealing material that combines the weather resistance of silicone sealant with the adhesive properties of polyurethane sealant. It is widely used in…
Flame-retardant PU foam features: Flame retardancy: This is its most important characteristic. When exposed to flame, it: Reluctant to ignite: Requires higher temperatures or a longer time to ignite. Slow flame spread: Once ignited, flames…
Key storage principles for PU foam: Keep in a cool, dry place at a constant temperature, away from light, and store upright. Temperature: Optimum storage temperature: Typically between 5°C and 25°C (check the product label…
PU Foam Curing and Trimming Waiting for Curing: Allow the sprayed foam to cure and expand naturally. Tack drying (a non-sticky surface crust) typically takes 10-30 minutes, but full curing (hardening the interior to its…
PU Foam Procedure Protection Wear: Always wear gloves, safety glasses, and a mask. Shaking the Can: Before use, shake the can vigorously for at least 20-30 seconds to ensure even mixing. It is normal to…
Preparing Foam Before Using Materials and Tools: Can of foam glue Matched plastic spray tube (usually included with the can) Cleaning agent (specialized detergent or acetone, for cleaning the spray tube and any uncured foam…
