| Item | Details |
|---|---|
| Product Overview | An innovative multifunctional eco-friendly treatment agent specially designed for immersion processes. This product must be used with the special LG706 2-in-1 Additive to simultaneously complete degreasing, derusting (scale removal) and protective conversion film formation for steel, aluminum and other common metals in a single step. Formulated with eco-friendly surfactants, complexing agents and chelating agents, it features strong cleaning power, low ecological hazard and easy operation, making it an ideal choice for efficient, energy-saving and simplified pretreatment processes. |
| Main Specifications | Appearance: Pale blue liquidpH=1–2 |
| Core Advantages & Features | 1. Highly integrated, one-step completion: Integrates powerful degreasing, rust/oxide layer dissolution and protective film formation in one bath, greatly shortening process flow and saving equipment, energy consumption and time.2. Excellent cleaning and film-forming performance:Strong cleaning power: Composite surfactant system effectively removes various processing oils, rust preventives and contaminants.Mild derusting/oxidation removal: Mildly removes floating rust on steel and oxide layer on aluminum through complexation and chelation while protecting substrates from over-corrosion.Protective conversion film: Forms an ultra-thin protective film on clean metal surfaces, providing short-term rust prevention and enhancing adhesion of subsequent coatings.3. Outstanding environmental and operational convenience:Eco-friendly: Free of chromate, nitrite, nickel salt and other harmful substances.Easy operation: Usable at room temperature without heating, simple management.Long service life: Stable bath, strong resistance to impurities, low maintenance cost.4. Material versatility: Suitable for mixed or separate treatment of steel and aluminum, especially ideal for multi-material or small-batch multi-variety production. |
| Process Parameters | Temperature: Room temperatureImmersion time: 3–10 minutesBath preparation ratio: 2.5% 2-in-1 conversion coating agent + 2.5% 2-in-1 additive |
| Application Scope | Applicable materials: Steel (carbon steel, alloy steel) and aluminum (die-cast aluminum, profiles, etc.). Compatibility test required for other non-ferrous metals (zinc, copper, etc.).Applicable contaminants: Light to medium oil (cutting fluid, rust preventive, drawing oil), floating rust, thermal oxidation color, natural aluminum oxide film.Application scenarios: Small-batch multi-variety production, maintenance workshops, production lines requiring simplified processes, multi-material mixed treatment.Subsequent processes: Short-term inter-process rust prevention, or pretreatment for painting, powder coating, bonding, etc. |
| Standard Operation Process | Bath preparation → Immersion treatment → Water rinsing → Post-treatment/drying1. Bath preparation:Add ~80% tap water into a clean plastic or plastic-lined tank.Under stirring, add 2.5% LG406 first, then 2.5% LG706.Top up water to working level and mix thoroughly. Adjust pH to 2.5–3.5.Note: Both components must be used in proportion.2. Immersion treatment:Fully immerse workpieces at room temperature for 3–10 minutes.Extend time for heavy oil or oxidation. Slight agitation improves uniformity.3. Post-treatment:Rinse immediately with running water (two-stage counter-current rinsing recommended).Neutralization and water sealing (weak alkaline water + dehydrating rust inhibitor) are highly recommended.Blow dry with compressed air or dry at low temperature immediately after rinsing. |
| Bath Management & Maintenance | 1. Daily monitoring: Check pH daily (2.5–3.5) to ensure balanced cleaning, derusting and film-forming.2. Maintenance & replenishment: Replenish at LG406:LG706 = 1:1 by volume when pH > 3.5, slowly adding under stirring until pH returns to range.3. Bath replacement: Replace completely if bath is turbid, oil accumulates excessively, or replenishment becomes ineffective. |
| Precautions & Safety | 1. Personal protection: Strongly acidic working solution. Must wear acid-resistant gloves, goggles and apron. Avoid skin and eye contact.2. Process limitations: Designed for light to medium oil and floating rust. Heavy grease, solid polishing paste, dense scale or severe rust require pre-cleaning. The thin film is for short-term rust prevention only; additional treatment required for long-term outdoor storage.3. Material testing: Conduct sample testing for special alloys or precision parts before use.4. Wastewater treatment: Acidic waste liquid containing metal ions and organics must be neutralized, precipitated and discharged up to standard. |
| Packaging & Storage | Packaging: 25kg/plastic drum, 1000kg/plastic drumStorage: Cool and ventilated area, avoid direct sunlight and high temperature. Keep sealed.Shelf life: 12 months (original sealed package) |
