JY Series Low-Temperature Sintering Powder: The Ultimate Solution for Full-Temperature Protection

In the demanding world of high-performance coatings and composites, finding a single material that can withstand extreme and fluctuating temperatures is a significant challenge. Traditional fillers often fail under thermal stress, leading to coating cracking, (powdering), and corrosion. The JY Series Low-Temperature Sintering Powder emerges as a groundbreaking solution, specifically engineered to conquer the full spectrum of high-temperature scenarios with precision and reliability.

Core Innovation: Stepwise Melting Technology for Unmatched Adaptability

The cornerstone of the JY Series' superiority is its patented Stepwise Melting Technology. Unlike conventional single-point melting materials that can create weak points and cracks during thermal cycling, the JY powders are designed to melt across a gradient. This technology enables the formation of a continuous, protective ceramic-like film over a broad temperature range from 300°C to 1100°C. As temperature rises, different components within the powder melt sequentially, seamlessly filling voids left by decomposing organic binders and creating a dense, coherent barrier that adapts to thermal expansion and contraction

. This effectively solves critical industrial pain points like cold-hot cycle cracking and protection gaps in wide-temperature domains.

Precision-Tuned Portfolio for Every Thermal Challenge

The JY Series offers a meticulously graded portfolio, allowing engineers to select the optimal product for specific temperature thresholds and performance requirements:

JY230 (Starts melting at ~350°C): The frontline defender against thermal shock and cracking. It initiates protection at lower temperatures, ideal for applications like commercial stove burners that face direct flame and rapid water cooling cycles.

JY270 (Starts melting at ~700°C): The versatile performer for anti-oxidation and enhanced adhesion. Its melting point suits environments around 600-800°C, such as motorcycle engine parts and exhaust systems, where it improves metal wettability and forms a mechanical interlocking grid to resist vibration-induced peeling.

JY290 (Starts melting at ~900°C): The high-temperature specialist for resisting thermal shock and acid/alkali corrosion at temperatures up to 1000°C.

JY1100 (<1100°C): The ultimate shield for extreme heat, such as boiler linings, where it begins melting around 750°C to isolate oxygen and drastically reduce the oxidation rate of the substrate.

Beyond Heat Resistance: Integrated Performance & Economic Benefits

The advantages of JY Series powders extend far beyond temperature tolerance, delivering a multi-functional performance package:

Superior Corrosion Resistance: The powders form a borosilicate glass network at high temperatures that captures free ions, creating stable silicates. This grants exceptional salt fog resistance exceeding 3000 hours (UL certified), tripling the anti-corrosion lifespan compared to many conventional products.

Enhanced Coating Economy: With a controlled oil absorption value of ≤19g/100g—approximately 25% lower than market averages—the JY Series significantly reduces resin consumption in coating formulations without compromising performance, leading to direct cost savings.

Excellent Compatibility & Stability: The entire series maintains a neutral pH of 7.0±0.5, ensuring superb compatibility and stability with various resin systems, preventing premature curing or degradation.

Global Environmental Compliance: Formulated with a lead-free recipe, the JY Series is certified for REACH and ROHS standards, eliminating export barriers and supporting sustainable manufacturing initiatives worldwide.
