Features of Acetoxy Bathroom Sealant: Advantages: Strong adhesion (especially to non-metallic substrates such as glass, ceramic, tile, and PVC). Fast cure (fast surface crusting). Excellent weather resistance. Generally good mildew resistance (specialized bathroom sealants may…
Neutral Silicone Sealant Storage Unopened Product: Keep the original packaging sealed: Ensure the aluminum foil seal or inner cap on the bottle/tube is intact and do not puncture it prematurely. Storage Environment: Temperature: The ideal…
Storage of Acidic Silicone Sealant Unopened (original sealed tube/cartridge): Cool and dry: This is the most important requirement. Store in a cool, stable temperature location. The ideal storage temperature range is typically 5°C to 25°C…
Key Principles for Storing Acrylic Sealant Cool: The recommended storage temperature is between 5°C and 25°C. Dry: Keep the environment dry and humidity low. Protected from light: Avoid direct sunlight, especially UV radiation. Sealed: Keep…
Curing principle of acrylic sealant The curing mechanisms of acrylic sealants can be broadly categorized into two types: physical curing and chemical crosslinking. This depends on the sealant’s formulation (primarily solvent-based or emulsion-based). 1. Physical…
How to judge the quality of foam glue by the cross section after the foam glue is cured Key Observation Point: Cell Structure Cell Size and Uniformity: High-Quality: Cells are small and uniformly distributed…
What is flame retardant foam “Flame-retardant foam” refers to a polyurethane foam sealant with the ability to prevent or slow the spread of flames. It combines the excellent filling, sealing, bonding, thermal insulation, and sound…
What are “front foaming” and “back foaming”? The terms “front-foaming” and “back-foaming” in foam adhesive refer to the primary stage and location of the foaming reaction during the manufacturing or application process of polyurethane…
What are high modulus and low modulus in sealants In the sealant industry, “modulus” refers to the elastic modulus, specifically the tensile modulus or secant modulus. It measures a sealant’s ability to resist deformation under…
How to speed up the curing of neutral silicone sealant Accelerating the curing speed of neutral silicone sealant primarily relies on understanding its curing mechanism. Neutral silicone sealant cures by reacting with moisture in the…
How to speed up the curing of acid sealants Accelerating the cure of acidic silicone sealants requires measures tailored to their curing mechanism. Acidic silicone sealants cure through a chemical reaction (condensation) with moisture in…
Can acrylic sealants be made transparent? The cost of transparency: Possible performance degradation: Removing titanium dioxide may reduce UV resistance and anti-yellowing properties (titanium dioxide acts as a UV shield). Reducing fillers may affect strength…
