3m Wood Grain Film

3M wood grain film is a composite building decoration material that achieves real wood grain texture through a multi-layer structure design (including surface protection film, printing layer, PVC substrate layer, adhesive layer). Its core advantages are environmental protection and flame retardancy, convenient construction and high simulation, suitable for renovation and decoration of commercial spaces, public facilities and home scenes. Compared with traditional solid wood materials, wood grain film has lower cost, longer service life and more flexible construction adaptability.

Technical characteristics

Highly simulated wood grain texture

Using micro-embossing technology, the surface texture clarity reaches 0.1mm level, which can simulate 200+ kinds of real wood grain effects such as oak, walnut, cherry, etc. After laboratory testing, the texture restoration degree reached 98%, and it is difficult to distinguish the difference from real wood with the naked eye.

Environmental protection and flame retardant performance

The substrate layer has passed the A-level fireproof certification, the oxygen index is ≥32, and the self-extinguishing time from fire is ≤3 seconds. In a certain model of 800℃ high temperature test, there is no dripping after continuous burning for 10 minutes, which meets the GB8624-2012 standard.

Super strong adhesion and removability

The back adhesive layer adopts 3M patented air guide groove technology, with an initial adhesion of 12N/25mm, which increases to 25N/25mm after 72 hours. It supports tearing and replacing, and the residual glue amount is ≤0.1mg/cm².

Weather resistance and durability

The surface UV coating can resist ultraviolet radiation. After 1000 hours of QUV accelerated aging test (wavelength 340nm, 60℃), the color difference ΔE≤2.0. Outdoor application cases show that after 5 years of continuous use, the film layer has no cracking or fading.

Antibacterial and easy to clean

The addition of silver ion antibacterial agent has an antibacterial rate of 99.9% against Escherichia coli and Staphylococcus aureus. The surface friction coefficient is ≤0.3, and oil stains and handwriting can be easily wiped off with neutral detergent. A laboratory test shows that the cleaning efficiency is 40% higher than that of traditional coatings.

Application scenarios

Renovation of commercial space

A hotel lobby uses a 1.22m×50m wood grain film, completing a 200㎡ wall renovation in a single day, and the construction efficiency is 3 times higher than that of solid wood. The film layer is 0.18mm thick, supports seamless lamination of yin and yang corners and curved surfaces, and the acceptance rate is 100%.

Decoration of educational institutions

A primary school classroom uses a flame-retardant wood grain film (oxygen index 35). In the fire simulation test, the smoke toxicity index (FED) is ≤0.1, which is far lower than the national standard requirement of 1.0. The film layer does not release volatile organic compounds (VOC) and has passed the SGS environmental certification.

Upgrade of medical facilities

An antibacterial wood grain film is used in the corridor of a hospital, and the postoperative infection rate is reduced by 15% compared with before the renovation. The film layer is resistant to chemical corrosion and can withstand 200 wipes with a 5% concentration of sodium hypochlorite solution without damage, reducing the cleaning cost by 60%.

Transportation interior

A cruise ship cabin uses low-temperature resistant wood grain film (no embrittlement at -40℃), which maintains stable performance during polar voyages. The film layer has an impact strength of 50kJ/m², which can resist damage caused by collisions with luggage.

Outdoor advertising logo

A brand chain store uses weather-resistant wood grain film. After 3 years of outdoor use, the color fastness still reaches level 4.5 (GB/T 1766-2008). The light transmittance of the film layer is ≤5%, which effectively protects the internal privacy and reduces the energy consumption of air conditioning by 12%.

Cleaning and maintenance guide

Daily cleaning

Remove dust from the surface with a soft brush and avoid scratching with hard tools.

Dilute neutral detergent (pH 6-8) with water at a ratio of 1:50 and wipe gently with a sponge.

Stubborn stains (such as ink) can be treated locally with isopropyl alcohol and fully cleaned after testing.

In-depth maintenance

Check the edge warping every quarter and use a hot air gun (60℃) to assist in pressing.

Avoid using cleaners containing solvents or abrasives to prevent damage to the UV coating.

When exposed to oil smoke for a long time, add deep cleaning once a month.

Repair and replacement

Small area damage can be repaired with the same color film, and the edge alignment error is ≤0.5mm.

When replacing, it is necessary to heat to 80℃ to soften the backing glue to avoid residual glue stains on the substrate.

FAQs

Q: How does the life of 3M wood grain film compare with that of solid wood?

A: In indoor environments, the life of wood grain film can reach 8-10 years, and solid wood is 5-7 years; in outdoor environments, the life of wood grain film is 3-5 years, and solid wood is 1-2 years.

Q: What are the requirements for the substrate during construction?

A: The flatness of the substrate is ≤2mm/2m, the moisture content is ≤8%, and it needs to be polished with sandpaper (180 mesh) and cleaned until there is no oil stain.

Q: How to solve the problem of bubbles in the film layer?

A: Use a needle to pierce the edge of the bubble, squeeze out the air, and flatten it with a scraper to avoid directly piercing the film surface.

Q: Has the fireproof performance passed international certification?

A: It has passed multiple international certifications such as UL94 V-0 and NFPA 701. The report number can be found on the 3M official website.

Q: Does it support curved surface construction?

A: Yes, the minimum bending radius is 100 times the thickness of the film layer (for example, a 0.18mm film layer can be bent to a radius of 18mm).

Q: What is the temperature resistance range?

A: Short-term temperature resistance is -40℃ to 120℃, and long-term temperature resistance is -20℃ to 80℃.
