Why Kingdeli’s sealant Superior: Evaluate Waterproof Performance Like an Expert
Key Factors in Evaluating Waterproof Silicone sealant
Composition and Material Properties of Waterproof Silicone sealant
What makes a waterproof silicone sealant great starts with what it’s made from. The best ones use 100% silicone polymers. These keep the sealant tough, stretchy, and able to stand up to rough weather. For example, the HY-3300 Weatherproof Neutral Silicone Sealant is a one-part product that stays good on the shelf and hardens at room temperature. It’s perfect for building projects and works well from -50℃ to +200℃ after it dries.
Some special kinds, like the HY-722 Sanitary Silicone Sealant, turn into a super strong, rubbery seal. They fight mold and don’t wear out fast, so they’re awesome for wet places like bathrooms or kitchens.
Adhesion Strength on Various Surfaces
One big thing to check when picking waterproof silicone sealant is how well it sticks to stuff. Top-notch sealants grab onto things like glass, aluminum, ceramic tiles, concrete, and even plastics. Take the HY-2300 Outdoor Neutral Silicone Sealant—it sticks really well to most building materials, like glass and aluminum.
This makes it super handy for all kinds of jobs, like sealing curtain walls or window frames. You don’t even need to add primers or do extra prep work.
Flexibility and Elasticity Under Stress
Silicone sealants often go in spots that wiggle or shake, like joints in buildings. That’s why they gotta stay bendy. The HY-2100 General Use Neutral Silicone Sealant does a great job between -50℃ and +100℃ after it sets. It stays stretchy even when a building gets hot and expands or moves a little.
High modulus types, like the HY-3300, hold strong when things get tough. They bend without cracking or peeling off.
Resistance to UV, Moisture, and Temperature Fluctuations
Waterproof silicone sealant really shows off when it faces sun, rain, or changing weather. Sunshine can wreck some sealants over time, but not the HY-739 Premium Acetic Silicone Sealant. It fights off UV rays and bad weather like a champ. It works great from -50℃ to +150℃ after drying.
This makes it perfect for indoor jobs or outside where it’s sunny or wet.
Methods for Testing Silicone Sealant Performance
Laboratory Testing Standards for Silicone Sealant Durability
To make sure every batch is good, companies test sealant with standards like ASTM C920 or GB/T14683-2017. These check how strong it is, how much it can stretch, and if it stays sticky after sitting in water.
Kingdeli’s HY-3300 Weatherproof Neutral Silicone Sealant passes ASTM C920-18 tests. That means it’s up to global standards for being tough and working well.
Real-World Simulation: Water Immersion and Weathering Tests
Lab tests are cool, but testing in real-life conditions is just as important. Dunking sealant in water for a long time shows if it stays stuck when it’s soaked. The HY-732 Acetic Silicone Sealant for Large Glass Wall is awesome for places with water all the time. It keeps water out, no matter what.
Measuring Curing Time and Post-Cure Hardness
How fast sealant dries can change how long a project takes. Quick-drying ones let workers move faster, but the sealant still needs to get hard enough to last. The HY-739 Premium Acetic Silicone Sealant dries fast so it’s not sticky. It’s also easy to smooth out for a neat look.
Once it’s dry, testers use a Shore A scale to check how hard it is. This makes sure it’s bendy but also strong.
Evaluating Shrinkage and Cracking Over Time
Good sealant doesn’t shrink or crack as it gets older. Kingdeli adds special stuff to keep their sealant fresh. For example, the HY-763 Silicone Sealant for Marble and Concrete fights mold and doesn’t wear out. This is super important for sealing things like stone that can soak up water.
