Introduction
Product Description
This product uses imported organic silicon acrylic emulsion as the base material, and water as the dispersing medium, making it an environmentally friendly building latex paint. It introduces organic silicon into the acrylic resin, forming a composite coating of organic and inorganic materials, thereby improving the stain resistance and durability of the latex paint. It is suitable for walls of buildings that require long-term protection, such as office buildings, hotels, and residences.
Product Characteristics
1. The Si-O bond energy of organic silicon in the silicon-acrylic emulsion is 27% higher than the organic C-C bond energy in general latex paint base materials, so the silicon-acrylic exterior latex paint has outstanding durability and weather resistance; 2. It has very low surface tension, and the silicon-acrylic exterior latex paint made from it has low water absorption and good water permeability resistance.
3. When the latex paint dries and forms a film, the siloxane can hydrolyze, forming a three-dimensional cross-linked Si-O-Si structure with an interpenetrating network, giving the coating excellent adhesion and water resistance.
Physical Parameters
Solid Content: ≥45%
Color: Refer to the color card of Dejiali
Drying Time: ≤2 hours (23+2)℃
Recoat Time: ≥4 hours (23+2)℃, not exceeding 7 days at most. Theoretical coverage rate: 5 square meters/kilogram (two coats). Packaging: 20 kg bucket (subject to actual packaging).
Storage: It should be stored in a cool, ventilated, dry place without frost (5~35)℃, with a shelf life of one year.
Construction Instructions
Surface Treatment: Before painting, the substrate surface should be clean, dry, flat, firm, and free of dust.
For newly constructed walls, remove surface dust, grease, and loose mortar, and repair any gaps in a timely manner.
For repainting walls, use a scraper to remove the original paint film, fill and smooth it out. Use appropriate methods as needed. Ensure that the moisture content of the pre-coated substrate does not exceed 10%, and the pH value does not exceed 10. Construction methods: brushing, rolling.
Mixing and Dilution: This product should not be diluted with water in principle. If the construction environment temperature is too high, a small amount of water can be added for dilution, not exceeding 3%. After dilution, mix thoroughly again. Construction conditions: construction temperature above 5℃; maximum relative humidity of the air 85%. Recoat interval: not less than 2 hours (23℃).
Tool Cleaning: Clean all tools with water immediately after painting.
Precautions: After applying the silicon-acrylic exterior latex paint, consider that the latex paint has a one-week water avoidance period. During this time, the silicon-acrylic exterior latex paint undergoes a complete drying process. If it is not completely dry and is exposed to rain, the silicon-acrylic exterior latex paint may fade and turn white. Be sure to avoid rainwater after construction.
Follow the standards of GB/T9755-2001 "Synthetic Resin Emulsion Exterior Wall Coatings" and GB 24408-2009 "Limit of Harmful Substances in Exterior Wall Coatings for Buildings."
Health and Safety
Avoid contact of the paint with eyes; if contact occurs, rinse with clean water. The site must be well-ventilated, and all health and safety regulations must be followed.
Note: The above information and data are based on laboratory and practical experience, and may vary due to factors such as construction processes, testing methods, and paint improvements.
