Water-based paint sealing for fiberboard? High-filling one-component solid-color primer? Spray gun cleanable with tap water? 【KDD AP1000Y】is your ideal solution!!!

1. Application Scenarios

Applicable Products: One-component water-based wood sealing solid-color primer, water-based wood tinting primer

Applicable Working Conditions: Coating for indoor furniture, cabinets, door panels and mouldings made of MDF fiberboard, plywood, rubber wood, pine wood and other wood materials prone to color bleeding / grain raising

Core Demands and Pain Points: Traditional water-based systems suffer from easy water absorption and grain raising of fiberboards, topcoat discoloration caused by tannin and grease exudation, poor adhesion; traditional two-component coatings feature complicated processes, high costs and low construction fault tolerance; ordinary one-component primers have insufficient sealing performance, poor sandability and inadequate filling power. Manufacturers are in urgent need of a one-component eco-friendly sealing system with fast drying speed, high hardness, excellent anti-grain raising performance and simple construction.

2. Core Technical Solution

Applicable Substrates: MDF medium-density fiberboard, man-made board, plywood, veneered board and other wood substrates

Coating Resin System: Water (alcohol) soluble self-crosslinking acrylic resin (AP1000Y), one-component system with no curing agent required, dilutable with alcohol, spray gun cleanable with tap water, eco-friendly and easy to operate.

Curing and Baking Conditions: Air drying for 2~4 hours before sanding; accelerated curing at low temperature of 40℃ for 30 minutes

Key Performance Indicators:

• Flexibility: Excellent, resist grain raising, inhibit wood grain bulging, prevent paint film collapse and adapt to substrate deformation
• Adhesion: Grade 0, penetrate into substrate capillaries, realize firm sealing and resist tannin migration
• Sandability: Fast drying (sanding available within 2-4 hours), good sandability and no sandpaper sticking
• Resistance: Good performance, dry paint film with excellent water resistance, block grease exudation and prevent yellowing and discoloration

4. Conclusion and Selection Suggestions

Conclusion: With self-crosslinking acrylic resin as the core material, KDD KDD AP1000Y one-component water-based sealing solid-color primer perfectly solves major pain points of water-based coatings including difficult sealing, grain raising and color bleeding on fiberboards. It integrates multiple strengths including simple construction, high filling power, fast drying and easy sanding, as well as spray gun water cleaning function, with lower overall cost than two-component coatings, which is perfectly suitable for large-scale wood coating production.

Selection Suggestions: Give priority to MDF fiberboard and color bleeding-prone solid wood (rubber wood / pine wood); the top choice for furniture and cabinet production lines pursuing efficient construction, low cost and environmental compliance; capable of directly replacing traditional two-component sealing primers, one-component sealing primers or white primers, and suitable for modern coating assembly lines requiring short delivery cycle.

6. FAQ

1. Q: Is the dilution and spray gun cleaning of AP1000Y resin convenient?
   A: Very convenient. This resin has good water solubility, which can be directly diluted with water or alcohol ether solvents, and the construction spray gun can be cleaned with tap water after use.

2. Q: How long should we wait for the next working procedure after using this resin as sealing primer?
   A: Under air drying or low-temperature baking conditions, surface drying only takes 5-15 minutes. Sanding operation can be carried out after 2 to 4 hours, and full drying takes less than 24 hours, which greatly shortens the overall production cycle.

3. Q: Does this one-component system meet the requirements of water resistance and weather resistance?
   A: It forms dense paint film after self-crosslinking, with good water resistance. Its weather resistance fully meets the usage requirements of indoor furniture.
