The #SolventFreeAdhesive trend exploded on Douyin, with views jumping from 8M to 42M in two weeks, driven by tightening VOC regulations. Yet most formulations overlook a critical enabler: low-viscosity silicone as an internal lubricant. Without solvents, resin viscosities often exceed 10,000 cSt—too thick for coating or dispensing. Adding <50 cSt silicone reduces viscosity dramatically

Suppliers of “low-odor” silicones for automotive interiors and children’s toys face rising complaints: products pass VOC tests yet emit faint chemical smells in real use. The hidden culprit? Residual alkaline catalysts like KOH or tetramethylammonium hydroxide (TMAH). Though not VOCs, these can hydrolyze slowly or react with fillers, releasing ammonia-like notes detectable in sealed envir

As solid-state battery and EV markets surge, demand for UL 94 V-0-rated potting compounds grows. Yet a common misconception persists: “Silicone is heat-resistant, so it must be flame-retardant.” Reality tells a different story. While methyl silicones have high flash points (>300°C), they decompose under UL 94’s 600–800°C flame into volatile cyclics (D4/D5) and flammable hydrocarbons. T

Domestic medical silicone gel breast forms are gaining traction, but some manufacturers cut corners by diluting with ordinary silicone oil. The result? A persistent tacky surface post-cure. Root cause: low-molecular cyclic siloxanes (D3–D6) in non-medical silicones migrate outward over time. Though invisible, these compounds create a greasy film, compromise aesthetics, and raise biocompat

Starting in 2026, Japan’s PMDA requires all imported cosmetic ingredients to submit detailed impurity declarations, including exact concentrations of metals like Fe, Cu, and Ni—typically below 5 ppm. Many Chinese exporters are caught off guard: their Certificates of Analysis (COAs) only state “complies with standards,” lacking numerical data. Japanese reviewers now reject such vague docum

Recently, water-based industrial paint makers report frequent fish-eyes and craters after adding silicone leveling agents. Initial blame falls on contamination, but the real culprit is surface tension mismatch. Acrylic resins typically exhibit surface tension of 30–40 mN/m, while conventional polydimethylsiloxane (PDMS) silicones sit at just 18–22 mN/m. When this gap is too wide, silicone

“Our formula is ready—except we’re missing the silicone’s submission code, and the supplier says ‘never heard of it!’” With China’s full implementation of the cosmetic ingredient safety information submission system in 2026, more and more brands are getting stuck at the final filing step: their silicone supplier cannot provide the NMPA-generated “submission code,” causing entire

Just as companies adapted to D4/D5 restrictions, the EU struck again: on February 20, 2026, ECHA officially added hexamethylcyclotrisiloxane (D6). Now, any substance or mixture placed on the EU market with D6 ≥ 0.1% (1000 ppm) triggers SVHC notification. Meanwhile, customers in cosmetics, electronics, and textiles are already demanding D6 < 100 ppm (0.01%).

“Why was our ‘PBAT+PLA’ bag classified as non-biodegradable?” Recently, market regulators in Zhejiang and Guangdong conducted special inspections on biodegradable plastic products. Multiple batches of shopping bags and trash bags labeled “fully biodegradable” were removed and fined because they contained non-degradable additives—specifically, conventional dimethyl silicone oil&nb

“Same formula, same filler batch—but thermal conductivity dropped from 5.2 to 4.9 W/m·K!” Multiple electronic adhesive manufacturers recently reported abnormal performance swings in thermal greases. Joint troubleshooting revealed the culprit wasn’t filler or process—it was batch-to-batch viscosity drift in the base silicone oil. Products labeled “1000 cSt” actually tested between 900–1100
