Chengdu Branch-brand LH-3 type room temperature, heating zinc phosphate solution

1. Overview: a zinc phosphate solution under a wide temperature range, which can be used at room temperature or elevated temperatures. Treated steel parts form a uniform, dense, thin phosphate coating, used in various coating pre-treatment. Since the film solid, smooth, particularly in automotive, motorcycle, engineering machinery, refrigerators and other requirements of high corrosion resistance, strong adhesion products. 2. Composition: A component: a base liquid, light green liquid; B component: neutralizer, pale white liquid; C components: accelerator, pale yellow liquid. 3. Technical Specifications: Item Index Total acidity (point) from 20 to 35 free acidity (point) 1.0 to 2.0 Promote the concentration (point) 1.5 to 3.0 (with higher concentrations in winter) process temperature (℃) 0 ~ 20 20 ~ 3030 - 35 Processing time (min) 3 2.5 1.5 4. Process: A: degreasing, descaling → water washing → phosphate → water washing (or not washing directly drying) → dried (drying is best) B: degreasing, descaling → water washing → conditioning → phosphating → water washing (or not washing directly drying) → dried (drying is best) 5. Packaging storage: 25kg or 30kg plastic drum, stored in a cool ventilated place, 1 year shelf life.
