Product Description
Guangdong Yongrong New Building Materials Co., Ltd. specializes in manufacturing high-end transparent primer series, including three major categories: water-based, oil-based, and solvent-based. Its advantages include high transparency to seal the substrate, strong alkali and mildew resistance, perfect preservation of natural textures, and significant improvement in topcoat adhesion and gloss. It is also environmentally friendly and wear-resistant, suitable for various scenarios. We sincerely invite distributors and engineering clients to wholesale and purchase Yongrong transparent primers in bulk and experience the one-stop supply service of a professional supplier.
Product Parameter
Product Feature
Yongrong transparent primer is a key base treatment material in architectural decorative coating systems, primarily used to seal substrate pores, enhance adhesion, provide alkali and mildew resistance, and improve the topcoat effect.
Based on the film-forming substance and solvent type, transparent primers can be divided into three main categories: water-based transparent primers, oil-based transparent primers, and solvent-based transparent primers. Detailed information and comparisons of each type are as follows:
I. Water-based Transparent Primers
1. Product Introduction: Yongrong water-based transparent 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 interior and exterior 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.
4. Technical Parameters
Item | Indicator
Solid Content | 12%-15%
Adhesion | ≥0.45MPa (with substrate)
Drying Time (25℃) | Surface dry 1-2 hours, recoat 2-4 hours
Water Resistance | No abnormalities after 24-hour immersion
1. Product Introduction
Yongrong oil-based transparent 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, suitable for outdoor or high-abrasion scenarios.
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 performance: VOC content 70-100g/L, pungent odor during application, requires good ventilation;
• Slow drying: Surface dry requires 4-6 hours, recoat interval 8-12 hours.
3. Application Scenarios
• Outdoor Facilities: Bridges, metal curtain walls, outdoor furniture, and other applications requiring long-term weather resistance;
• Dark Wood: 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.
4. Technical Parameters
Item | Index
Solid Content | 40%-60%
Hardness | 2H-3H (pencil hardness)
Drying Time (25℃): Surface dry 4-6 hours, recoat 8-12 hours

III. Solvent-Based Transparent Primer
1. Product Introduction
Yongrong solvent-based transparent 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 capacity and fast drying, making it suitable for wood repair or rapid construction applications.
2. Product Features
• High filling capacity: Can fill wood grain pores up to 1mm deep in one pass, resulting in high construction efficiency;
• Quick drying: Surface dries in just 30 minutes, suitable for projects with tight deadlines;
• Poor environmental performance: 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, requiring rapid restoration of appearance;
• Temporary protection: Surface treatment of temporary facilities or equipment used for short periods on construction sites.

V. General Product Parameters and Application Guidelines
1. Theoretical Consumption
• Water-based transparent primer: 0.15-0.2 kg/m² (one coat);
• Oil-based transparent primer: 0.1-0.15 kg/m² (one coat);
• Solvent-based transparent primer: 0.2-0.3 kg/m² (one coat).
2. Packaging Specifications: Water-based: 18kg/bucket/18L, 20kg/bucket/20L; Oil-based: 5kg/bucket/5L, 20kg/bucket/20L; Solvent-based: 5kg/bucket/5L, 20kg/bucket/20L (5kg uses Yongrong 5L black glue bucket, 18kg uses Yongrong 18L black art paint bucket, 20kg uses Yongrong 20L black glue bucket)
3. Storage Conditions: All types must be stored in a cool, dry place, away from direct sunlight. Shelf life is 12 months.
4. Surface Preparation: Remove dust and oil stains. Moisture content <10%, pH value <10; New walls require curing for at least 28 days; old walls need to be sanded smooth.
5. Safety Precautions: Keep oil-based and solvent-based products away from fire sources. Wear a respirator during application. Water-based products can come into direct contact with skin, but avoid contact with eyes.
VI. Summary and Purchase Recommendations
• For home renovations, Yongrong water-based transparent primer is the first choice: environmentally friendly and quick-drying, suitable for interior walls and light-colored wood.
• For outdoor or high-abrasion applications, choose Yongrong oil-based transparent primer: high hardness and strong weather resistance, suitable for bridges and metal curtain walls.
• For temporary repairs, use Yongrong solvent-based transparent primer: quick-drying and high-filling, suitable for filling pores in dark wood.
