Elastic Coating

Elastic coating is a kind of ultraviolet curing coating with special properties, which is mainly used for the coating of wooden floors, which can provide good protection and decorative effects for wooden floors. Its main components are elastic UV polyurethane and other resins. After ultraviolet curing, these resins can form a film with a certain elasticity, which can be deformed synchronously with the thermal expansion and cold contraction of the wood, effectively avoiding coating cracking caused by changes in temperature and humidity. It is especially suitable for environments with large temperature and humidity changes.

1. Product Title

Elastic coating is a kind of ultraviolet curing coating with special properties, which is mainly used for the coating of wooden floors, which can provide good protection and decorative effects for wooden floors. Its main components are elastic UV polyurethane and other resins. After ultraviolet curing, these resins can form a film with a certain elasticity, which can be deformed synchronously with the thermal expansion and cold contraction of the wood, effectively avoiding coating cracking caused by changes in temperature and humidity. It is especially suitable for environments with large temperature and humidity changes.

 

2. Core Value Proposition

  • Solving high-pollution challenges: Designed for environments such as kindergartens and kitchens where floor surfaces easily get stained by markers and grease, and where frequent wiping or toy impact often causes coating peeling.
  • Core features: Achieves ISO 26987 Level 0 stain resistance (stains can be wiped clean in 10 seconds). Elastic coating + Grade 0 adhesion ensures a 0% peeling rate.
  • Additional assurance: Eco-friendly formula with VOC ≤5 (compliant with children-space standards). UV rapid curing in 3–30 seconds without disrupting normal use of the space.

 

Core Advantages of Elastic coating

 

1. Anti-fouling and anti-shedding core technology
  • Low–surface-energy formula: Incorporates organosilicone and other low–surface-energy materials to form an anti-stain "protective film" after curing. Meets ISO 26987:2008 Level 0 stain-resistance standards, serving as an upgraded version of thin-coat / skin-feel UV coatings (which typically reach only Levels 2–3).
  • Enhanced elastic adhesion: Uses elastic crystal putty (viscosity 10,800–15,100 CPS) as the base layer, combined with three layers of transparent sanding primer (two more layers than thin-coat systems). This achieves deep mechanical anchoring between coating and substrate, resulting in a 0% peeling rate.
  • Impact-resistant formulation: The elastic coating has an elongation ≥15%, allowing it to absorb impacts from children's toys and kitchen utensils, preventing cracking. This makes it more suitable for high-impact environments compared to ultra-wear-resistant coatings (elongation ~5%).

2. Adaptability to high-pollution scenarios
  • Target applications: Kindergarten activity rooms, kitchen work areas, restaurant spaces, and eldercare facilities-environments that are prone to staining, frequent wiping, and repeated impact.
  • Compatible substrates: Solid wood flooring, bamboo flooring, and multilayer engineered flooring (covering the mainstream substrates used in high-pollution areas).
  • Non-disruptive construction: UV rapid curing enables kindergartens to complete work over the weekend and reopen normally on Monday, and allows kitchens to finish work at night and resume business the next day.

3. Environmental protection and long-term maintenance
  • Environmental compliance: VOC ≤5 (far lower than industry standards). Solvent-free curing meets environmental requirements for children's spaces and food-contact areas.
  • Maintenance cost reduction: Stains can be wiped clean in 10 seconds, reducing cleaning frequency by 50%. Coating lifespan is 8–10 years-twice that of ordinary UV coatings (3–5 years), reducing the need for refinishing.
  • Safety assurance: The coating surface is smooth and burr-free (GB/T 9754-2007, gloss 5–7°), preventing scratches or injuries to children.

Curing Energy / Key Parameters

Differentiated Purpose

1

Substrate preparation: sanding with 320-grit sandpaper + degreasing & dust removal + moisture check (≤8%)

–

Suitable for high-humidity environments (kitchens); improves adhesion

2

Roll-coat water-based UV adhesion primer (JF-ZM101) + IR drying

–

Base adhesion layer

3

Roll-coat low-odor UV adhesion primer (JF-ZM121) + UV semi-curing

147–250 mJ/cm²

Enhances interlayer bonding, suitable for high-frequency wiping

4

Roll-coat elastic crystal putty (JF-ZM308) + UV semi-curing

78–118 mJ/cm²

Elastic underlayer to absorb impact and prevent peeling

5

Roll-coat UV elastic wear-resistant primer (JF-ZM608) + UV semi-curing

76–125 mJ/cm²

Dual protection: elasticity + wear resistance

6

Roll-coat elastic crystal primer (JF-ZM508) + UV semi-curing

103–205 mJ/cm²

Optimizes coating elasticity to prevent cracking

7–9

Roll-coat 3 layers of transparent sanding primer (JF-ZM521B) + semi-curing after each layer

108–213 mJ/cm² per layer

Three-layer sanding primer boosts adhesion and prevents peeling (thin-coat systems use only 1 layer)

10

Light sanding with 320-grit sandpaper

–

Removes burrs and ensures smooth wiping

11

Roll-coat 5-degree anti-scratch topcoat (JF-ZM805-KW) + final curing

350–500 mJ/cm²

Stain-resistant final finish, compliant with ISO 26987 Level 0

 

Construction Notes

 

  • Environmental requirements: Construction temperature should be 5–30°C to prevent negative effects on coating flowability.

 

  • Equipment compatibility: Due to the high viscosity of the elastic putty, the use of a high-pressure mixing roller coater is recommended to ensure an even coating layer.

 

  • Storage handling: Unopened products have a 12-month shelf life when stored in a dry, ventilated environment. Avoid high temperatures and direct sunlight.
