Product Description
As a professional paint manufacturer, Guangdong Yongrong New Building Materials Co., Ltd. has launched a series of high-performance color-matching primers, covering water-based, oil-based, and solvent-based products. The core selling points include excellent sealing properties, super strong adhesion, high opacity and uniform base color, and significant savings in topcoat usage. They are environmentally friendly, quick-drying, weather-resistant, and wear-resistant. We welcome contractors and decoration customers to purchase Yongrong color-matching primers in bulk, or contact us directly to become a long-term supplier partner.
Product Parameter
Product Feature
Yongrong color-matching primer, as a key base material in architectural decorative coating systems, is primarily used to seal the substrate, enhance adhesion, and provide a base color that matches the topcoat, thereby reducing topcoat usage and improving the decorative effect.
Yongrong color-matching primer, through its design that matches or closely resembles the topcoat color, achieves the following functions:
• Sealing the substrate: Prevents efflorescence and moisture absorption from the substrate, protecting the topcoat's performance;
• Enhanced adhesion: Improves the bonding strength between the topcoat and the substrate;
• Saves topcoat: High hiding power reduces the number of topcoat coats;
• Unified base color: Prevents uneven coloring of the topcoat caused by differences in substrate color.
Based on the film-forming substance and solvent type, color-matching primers can be divided into three main categories: water-based color-matching primers, oil-based color-matching primers, and solvent-based color-matching primers. The following is detailed information and a comparison of each type:
1. Product Introduction: Yongrong water-based color-matching primer uses water as a solvent and acrylic copolymer emulsion or polyurethane dispersion as the film-forming substance. It features high transparency and low VOCs, making it suitable for various substrates such as indoor and outdoor walls and wood.
2. Product Features
• Environmentally Friendly and Safe: VOC content as low as 5-8g/L, free of benzene, formaldehyde, and other harmful substances, meeting EU E0 and infant safety standards;
• High Transparency: Light transmittance ≥92% after drying, perfectly showcasing wood grain or the natural color of the substrate, avoiding yellowing;
• Convenient Application: Can be directly diluted with water (dilution ratio ≤10%), easy to clean tools, surface drying time only 1-2 hours, recoating interval 2-4 hours;
• Relatively Weak Weather Resistance: Abrasion and water resistance are slightly lower than oil-based products, suitable for indoor or dry environments.
3. Application Scenarios
• Indoor Walls: Children's rooms, bedrooms, and other spaces with high environmental protection requirements;
• Light-Colored Woods: Furniture or decorations made of white oak, cherry wood, etc., where the natural grain needs to be protected;
• Old Wall Renovation: Sealing treatment for slightly powdery substrates, enhancing topcoat adhesion.

1. Product Introduction
Yongrong oil-based color-matching primer uses organic solvents (such as xylene, esters) as diluents and polyurethane or epoxy resin as film-forming substances. It features high hardness and high abrasion resistance, making it suitable for outdoor or high-abrasion environments.
2. Product Features
• Excellent Performance: Hardness up to 3H, abrasion resistance 2-3 times that of water-based products, strong water and alcohol resistance;
• High Gloss: Mirror-like finish after drying, suitable for decorative furniture or metal surfaces;
• Poor Environmental Friendliness: VOC content 70-100g/L, pungent odor during application, requires good ventilation;
• Slow Drying: Surface dry in 4-6 hours, recoating interval 8-12 hours.
3. Application Scenarios
• Outdoor Facilities: Bridges, metal curtain walls, outdoor furniture, and other applications requiring long-term weather resistance;
• Dark Woods: Sealing and protection for coarse-grained or dark-colored substrates such as walnut and ebony;
Industrial Equipment: Chemical workshops, machinery, and other surfaces requiring resistance to chemical corrosion.

1. Product Introduction
Yongrong solvent-based color-matching primer uses organic solvents such as banana oil and ketones as carriers, and nitrocellulose or unsaturated polyester resin as film-forming substances. It combines high filling power and fast drying, making it suitable for wood repair or rapid construction scenarios.
2. Product Features
• High Filling Power: Can fill wood grain pores up to 1mm deep in one pass, resulting in high construction efficiency;
• Fast Drying: Surface dry in only 30 minutes, suitable for projects with tight schedules;
• Poor Environmental Friendliness: VOC content is as high as 80-100g/L, with a strong odor, requiring strict protection;
• Yellowing Risk: Prolonged exposure to ultraviolet light can easily cause yellowing, unsuitable for light-colored substrates.
3. Application Scenarios
• Wood Repair: Filling holes and cracks in dark wood to quickly restore appearance;
• Temporary Protection: Surface treatment of temporary facilities or equipment used for short periods on construction sites.
