Core Information

1. Product Introduction

2. Core Value Proposition

Addressing pain points in premium spaces: Traditional flooring offers limited color options and lacks visual character, making it unable to meet the design and value-added needs of high-end environments.
Core benefits: Utilizes tannic acid / metal-salt chemical color-changing technology to achieve both natural wood grain and dynamic color effects. Color depth can be precisely controlled, enabling a 30% increase in product value.
Additional assurance: Low-VOC eco-friendly formula with 3–30 second rapid UV curing, ensuring project timelines are unaffected while meeting the environmental requirements of premium spaces.

Core Advantages of Reactive stain

1. Dynamic color-changing core technology

Chemical color-changing formula: Incorporates specialized chromogenic agents such as tannic acid and metal salts, which undergo oxidation/chelation reactions with wood components to create stable and reversible color changes-distinct from the "static coloring" of conventional dyes and stains.
Precise color control: By adjusting the coating thickness (0.1–0.3 mm), a gradient shift from light wood tones to deep brown can be achieved, meeting diverse design requirements.
Compatibility assurance: The color-changing coating integrates seamlessly with UV-curing systems. After curing, it reaches a hardness of ≥2H (GB/T 6739-2006) with wear resistance not lower than standard UV coatings, ensuring durability without compromising aesthetics.

2. High-end scenario adaptability

Target applications: Premium residential living rooms, boutique hotel guest rooms, homestay public areas, and commercial showrooms-spaces that emphasize strong design aesthetics and require visual value enhancement.
Suitable substrates: Natural solid wood flooring such as oak, walnut, and ash, where the color-changing effect is more pronounced compared to engineered floors with artificial grain patterns.
Construction advantages: UV rapid curing ensures that short project timelines in high-end developments are not affected. The color-changing process requires no additional chemical agents, is environmentally friendly, and produces no secondary pollution.

Environmental protection and premium advantage

Environmental compliance: Low-VOC formula with solvent-free curing, meeting the requirements of GB 18581-2020: Limitations of Harmful Substances in Wood Coatings for Interior Decoration. Fully compatible with environmental inspections for high-end spaces.
Product value enhancement: After treatment, the flooring's retail price can increase by 30%–40%, becoming a "differentiated selling point" in premium interior design. Customer contract conversion rates can improve by 25%.
Long-term stability: The color-changing effect remains long-lasting without fading. Under normal use, color attenuation is ≤5% over 8 years, eliminating the need for frequent refinishing.

Construction process

Dedicated construction process

Step	Construction content	Curing energy / Key parameters	Differentiation Objectives
1	Substrate preparation: fine sanding with 320-grit sandpaper + degreasing & dust removal + moisture check (≤8%)	–	Ensures wood reactivity and promotes a uniform color-change reaction
2	Roll-coat water-based UV adhesion primer + IR drying	–	Provides the foundational adhesion layer for the color-changing coating
3	Roll-coat low-odor UV adhesion primer + UV semi-curing	150–250 mJ/cm²	Enhances interlayer bonding strength and prevents delamination of the color-changing layer
4–6	Roll-coat 3 layers of crystal primer (JF-ZM501) + semi-curing after each layer	100–200 mJ/cm² per layer	Key differentiator: Three primer layers improve wood penetration, enabling a more complete color-change reaction
7	Roll-coat color-change coating (JF-ZM471) + room-temperature reaction for 3–8 hours	–	Core differentiator: Critical chemical color-change step; reaction time adjusted based on desired color depth
8	Roll-coat transparent sanding primer + UV semi-curing	100–200 mJ/cm²	Locks in the color-change effect and improves surface leveling
9	Light sanding with 320-grit sandpaper	–	Removes burrs and ensures a smooth surface for the topcoat
10–11	Roll-coat 2 layers of 5-degree anti-scratch topcoat (JF-ZM805D) + final curing	350–500 mJ/cm² (final cure)	Provides wear resistance and long-lasting color retention

Construction Precautions

Environmental requirements: Construction temperature should be 20–30°C with humidity ≤60% to prevent high temperature or humidity from affecting the uniformity of the color-change reaction.
Color-change control: A "thickness–time–color" parameter chart is provided to help applicators precisely manage the final effect.
Storage & handling: Unopened products have a 12-month shelf life when stored in a dry, ventilated environment. After opening, the color-changing coating should be used within 30 days to prevent degradation of the chromogenic agents.

Technical Specifications

Test Project	Test Standards	Standard value	Differences from other UV coatings
Colorant (chromogenic agent) content	Industry standard for color-changing coatings	≥5%	Conventional UV coatings contain no chromogenic agents
Viscosity (color-changing coating)	GB/T 9751.1-2008	50–150 CPS	Much lower than super-wear-resistant (5000–7000 CPS) and elastic coatings (10,800–15,100 CPS), enabling deep penetration for effective color change
Color adjustment range	Visual color test	Light wood tone → deep brown (3 adjustable levels)	Other UV coatings have fixed colors with no adjustability
Adhesion	GB/T 9286-1998	Grade 0	Combined with 3 layers of crystal primer to ensure the color-changing layer does not peel off
