| Product Overview | LG907 Silane Sealer is an eco-friendly, phosphorus-free and chromium-free metal surface treatment agent based on silane coupling agent technology. It forms an ultra-thin (nano-scale), dense, three-dimensional network organic-inorganic hybrid silane film on the clean steel surface through chemical adsorption and self-assembly. The film bonds with the substrate through strong Si-O-Fe covalent bonds, and forms firm chemical bonding with subsequent organic coatings (paint, powder, adhesive) through abundant Si-OH functional groups, providing excellent adhesion, corrosion resistance and long-term durability. It is an ideal alternative to traditional phosphorus and heavy metal containing processes such as phosphating and ceramic conversion coating. |
| Chemical Properties | Appearance: Milky white or transparent liquidStock solution pH: 8±1Working solution pH: 7±1 |
| Product Features | 1. Excellent adhesion: Forms chemical bonds with the substrate and coating, significantly improving the coating adhesion (usually 0 grade by cross-cut method) and impact resistance2. Superior corrosion resistance: The dense silane film effectively blocks corrosive media, greatly extending the neutral salt spray test (NSS) time, especially suitable for matching with cathodic electrodeposition (CED)3. Ultra-thin & eco-friendly: Film thickness is only 50-500nm, does not change the workpiece size; phosphorus-free, chromium-free, heavy metal-free, simple wastewater treatment, compliant with RoHS, REACH and other regulations4. Strong versatility: Suitable for mixed line processing of various substrates such as cold rolled plate, hot rolled plate, galvanized plate (GI), galvalume plate (GL), simplifying production management5. Easy operation: Can be used at room temperature or medium temperature, both immersion and spraying are available, low energy consumption, no sediment, easy bath management6. Good heat resistance: The heat resistance of silane film is better than some organic coatings, and the performance is stable during the subsequent drying process |
| Technical Parameters | Working solution pH: 7±1Working temperature: Room temperature - 50°CTreatment time: 40-90 seconds for effective spraying, 2-3 minutes for immersionTank preparation ratio: 2-3% |
| Application Scope | Applicable substrates: Cold rolled steel, hot rolled steel, alloy steel, cast iron, galvanized steel, galvalume plate, aluminum alloy (verification required), especially suitable for multi-material co-line productionApplicable coatings: Cathodic electrodeposition (CED), powder coating, liquid paint, plastic sprayingApplicable industries: Automobile and parts, home appliances (chassis, panel), sheet metal processing, building materials, agricultural machinery, metal furniture and all other fields requiring coating protection |
| Standard Process Flow | Perfect Degreasing → Two-stage Water Washing → Deionized Water Washing → Silane Treatment → Drying |
| Standard Operation Method | 1. Pre-treatment (key to success): Must use matching special degreaser to ensure the workpiece surface reaches a fully hydrophilic state with continuous water film and no residue; adopt two-stage countercurrent flowing water washing to fully remove degreaser residue; the final rinse must use deionized water with conductivity <20μS/cm to minimize the impurity ions brought into the silane tank, and the dripping water conductivity of the workpiece after leaving the tank should be <50μS/cm2. Silane treatment (core process): Immerse or spray the pre-treated qualified workpiece with LG907 working solution, strictly control the treatment time, temperature and pH value; pH is the key to reaction activity, which must be monitored daily and precisely controlled with special regulators; slight stirring or appropriate spray pressure helps to form a uniform film3. Post-treatment & drying: After treatment, it can be drained directly, or rinsed with clean deionized water for a very short time (<15 seconds) to remove loose attachments, and then drained thoroughly; immediately enter the drying oven, bake at 100°C-120°C for 10-20 minutes to complete the cross-linking and curing of the silane film and obtain the best performance |
| Precautions & Safety Instructions | 1. Personal protection: Wear protective gloves to avoid direct contact with the solution2. Process rules: Pre-treatment is the core of the silane process, any degreasing or water washing error will lead to the failure of the silane film; it is strictly forbidden to use tap water/groundwater to prepare and replenish the working solution, deionized water must be used; strictly control the pH value, out of range will lead to abnormal film formation reaction3. Film verification: Visual inspection should show a uniform, iridescent complete water film after drying; regularly conduct salt water immersion test, cross-cut adhesion test, and salt spray test together with the coated workpiece4. Wastewater treatment: The waste liquid from tank replacement has high COD, but no heavy metals, which can be discharged after reaching the standard through conventional treatment such as neutralization and flocculation |
| Storage & Packaging | Packaging specification: 25kg/plastic drum, 1000kg/plastic drumStorage condition: Store in a cool and ventilated place, avoid direct sunlight and high temperatureShelf life: 12 months from the date of production under intact and unopened original packaging |
