Litron is a type of coating that is mostly used to cover glass surfaces against laser radiation. This type of coating is used to produce intensified lenses, as well as in the electronics, aerospace, medical and other industries to reduce the effect of laser radiation on electronic components and quality-sensitive surfaces.
Due to its high resistance to laser rays, this type of coating is usually used in industries that need to protect surfaces with high readability against laser rays.
Letron coating is generally made of a material called magnesium fluoride (MgF2). This material, having characteristics such as high transparency at about 1250 nm, high electrical insulation, high durability and resistance to thermal shock, chemical stability and very low permeability to laser rays, is suitable for protecting surfaces against this type of radiation.
Letron used in the wood industry is made from wood chips, and there is both a product called Letron sheet and a product called Letron coating in the market, which we will explain further.
Where is Letron coating used?
Letron coating is used as a main material in various industries. Below are some of the uses of Letron coating for you:
1- Intensified lenses: Letron coating is used in the manufacture of optical and intensified lenses.
2- Electronics industry: In this industry, Letron coating is used to protect electronic components and quality-sensitive surfaces against laser radiation, as well as to reduce electrostatic effects.

6- Military industries: Letron coating is used in the manufacture of military and military-technical equipment to protect quality-sensitive surfaces against laser rays and other electromagnetic rays.
In general, due to the unique properties of Letron coating, this material is used in various industries to protect quality-sensitive surfaces against laser rays and other electromagnetic rays, and to improve image quality and device performance.
7- Wood industry
The use of Letron coating in the wood industry
In the wood industry, Letron coating is also known as paper coating (Letron is the name of one of the paper producing companies that also produces Letron paper coating). It should be used against laser rays and thermal shock to protect wood surfaces against these types of effects. Also, for laser cutting of wood, Letron coating can be placed on the surface of the wood to reduce the effect of the laser beam on the surface of the wood. In general, Letron is considered one of the weak coatings among the types of coatings available in the market, which can be used for both chipboard and MDF, and is usually used in the production of cheap furniture and accessories.
Some of the applications of Letron coating in the wood industry are:
– Protection of wood surfaces against thermal shock and laser radiation
– Covering wood surfaces against sunlight and preventing color change and cracking of wood surfaces due to oxidation
– Reduction of electrostatic effects in laser cutting of wood
– Improving the readability of images obtained from laser cutting of wood
In general, the use of Letron coating in the wood industry can improve the quality and useful life of wood surfaces, and also reduce the costs of repairing and replacing wood surfaces due to damage caused by laser rays, thermal shock, and humidity.
Features of Letron coating suitable for wood industry
Due to its unique features, Letron coating has become a significant substitute in the wood industry as a substrate oil and paint. The features that make Letron coating suitable for use in the wood industry are:
1- Resistance to thermal shock: Letron’s coating, having properties of resistance to thermal shock, is able to give wood surfaces an excellent coating against sunlight and laser rays.
2- Electrical insulation: Letron coating is also the best choice for protecting wood surfaces that are sensitive to quality against laser radiation, with properties such as high electrical insulation.
3- Chemical stability and oxidation resistance: With its chemical stability and oxidation resistance, Letron coating is able to give wood surfaces an excellent coating against biological and chemical factors.
4- High durability: Letron cover has high durability.
Advantages and disadvantages of Letron coating
Advantages of Letron coating:
– Protection of wood surfaces against thermal shock and laser radiation
– Covering wood surfaces against sunlight and preventing color change and cracking of wood surfaces due to oxidation
– Reduction of electrostatic effects in laser cutting of wood
– Improving the readability of images obtained from laser cutting of wood
– Resistance to biological and chemical factors
– High durability and prevents scratching and cracking of wood surfaces
Of course, as mentioned, in general, Letron veneer has weaker positive characteristics than other wooden veneers at the moment.
Disadvantages of Letron coating:
– The relatively high cost of Letron coating compared to conventional paints makes it difficult to use to cover wood surfaces.
– The need for special equipment and technology to apply Letron coating on the wood surface may be more difficult and complicated than covering the wood surface with ordinary colors.
– If you don’t use the right equipment and technology, the use of Letron coating may lead to big errors in the quality of wood surface coating.
According to the mentioned advantages and disadvantages, the use of Letron coating in the wood industry has become a significant alternative as an oil and substrate paint. However, the successful implementation of this method requires appropriate equipment and technology, and its high costs may lead to challenges for its wider implementation in the wood industry.
The relatively low thickness of the letron coating causes the lack of proper coverage of the work surface, and the thin material of the letron causes the low impact resistance of this coating.
Letron may have a beautiful appearance, but compared to vacuum membrane and melamine covers, it can be said that it has nothing to say in terms of beauty.
Is Letron coating suitable for cabinet making?
Yes, using Letron coating for low-cost cabinet making can be an effective and suitable method. This method is used as an alternative to conventional paints in covering wood surfaces and has advantages such as protecting the wood surface against thermal shock and sunlight, reducing electrostatic effects in laser wood cutting, resistance to biological and chemical agents, and high durability. . Using Letron-coated MDF is a better option than using Letron-coated chipboard for cabinet making.
In addition, Letron coating has the ability to cover wood surfaces with different colors and is specially made for cabinets. Also, the images obtained from laser cutting of wood with Letron coating are improved and used for modern and stylish cabinet making. However, the implementation of Letron coating method requires appropriate equipment and technology, and its high costs may lead to challenges for its wider implementation in the cabinet making industry.
Suitable adhesive for Letron coating
Letron coating is used as a wood surface coating method in the wood industry. This coating is used to cover wood surfaces using polymer and electrostatic technology. In this method, instead of using conventional paints, Letron coating is applied to wood surfaces using a chemical process.
To apply Letron coating on wood surfaces, a suitable glue is used to stick the coating to the wood surface. The adhesives used for this purpose must have special characteristics that are resistant to thermal shock and laser radiation and also cover the wood surface well.
One of the glues used in the wood industry to apply Letron coating is Polyamide glue. This glue is generally used as a base glue for metal sheets and has the ability to resist thermal shock and laser radiation. Also, polyamide glue has characteristics such as resistance to water, moisture and chemicals, which makes it one of the suitable glues to be used in the method of covering the wood surface with Letron coating.
