DM7680 Transparent and reflective film

DM7680 cleverly combines the two optical properties of reflection and transmission, and is specially developed for modern lighting and advertising sign design. Under direct light, the material exhibits excellent reflective performance, effectively improving visibility and ensuring clear information transmission even in strong light environments. At the same time, DM7680 has a single-sided light-transmitting property, which makes it show a soft and uniform light effect under backlight conditions, and is particularly suitable for surface applications of LED luminous characters. As a surface covering material for luminous characters, the reflective function of DM7680 can enhance the brightness and contrast of the sign during the day, and at night it can make the LED light more evenly distributed, avoiding local overbrightness or dark spots, and improving overall visual comfort. DM7680 not only enhances the visual impact of advertising display, but also achieves an ideal balance between aesthetics, practicality and energy saving. It is an ideal choice for indoor and outdoor LED sign systems.

Features

Features

1.High light transmittance

The light path is optimized by the microprismatic structure, and the light transmittance can reach more than 90% (common light-transmitting films are usually 80%~85%), which significantly reduces light energy loss and improves display or lighting efficiency.

2.Ruggedness

The surface of DM7680 is covered with a high-strength wear-resistant coating, which can resist environmental erosion such as ultraviolet rays, acid rain, salt spray, and adapt to extreme climatic conditions such as high temperature, severe cold, and humidity.

Passed ISO 9001 quality management system certification, the products comply with GB/T 18833 "Road Traffic Reflective Sheeting", EN12899 (EU standard) and ASTM D4956 (US standard) and other domestic and foreign standards.

3.Safety and environmental protection

DM7680 complies with the EU ROHS directive and relevant domestic environmental protection standards. It has excellent flexibility and can fit curved surfaces or complex shapes of substrates, reducing construction difficulty.

// DM // Product Use Tips

01 /

How to test the reflective effect?

1. Take pictures with a mobile phone at a distance of more than 3 meters in a dark environment.

2. Place the flashlight more than 5 meters in a dark place and shine the light on the reflective part from the height of the nose tip.

3.Conduct the test with a car at a distance of more than 20 meters in a dark environment.

02 /

How is the adhesion performance?

1. The reflective adhesive backing is a chronic adhesive. The longer the time, the stronger the stickiness.

2. Please be careful when pasting and sticking it in one time. Pasting it many times will affect the adhesion.

3. Please stick it firmly when pasting. It will be completely firm after 72 hours and can be used all day long.

4. If you need to remove it after long-term use, please heat it up with a hair dryer before removing.

5.Surface residue glue can be wiped off with alcohol or toilet water.

03 /

Why is the reflective effect I tested not strong?

The reflection you tested was weak because your testing method was incorrect.

1. Please conduct the test at a distance of at least 3 meters. Due to the issue of reflection angle, it needs to be at a certain distance away.

2. The principle of reflective stickers is that wherever the light source comes from, the reflection will return to the light source, thereby alerting the driver.

3. The reflective intensity of reflective stickers is directly proportional to the light intensity; the stronger the light source, the stronger the reflection.
