Yuxin Koolfilm Primary Dyed Film: 

• Excellent Color Stability: They feature rich and vibrant colors that remain consistent over time, without fading or changing hue due to exposure to sunlight or other environmental factors.
• Good Visibility: These films offer a clear view from the inside, allowing for unobstructed vision while still providing a certain degree of privacy from the outside.
• Effective Heat and Glare Reduction: They can significantly reduce solar heat gain and glare, making the interior more comfortable and reducing the need for excessive air - conditioning.
• High Quality Adhesive: The adhesive used is strong enough to ensure the film adheres firmly to the window surface but is also removable without leaving residue when it needs to be replaced.
• Durability: They are resistant to scratches, abrasions, and cracking, which ensures a long - lasting performance and maintains their appearance over an extended period.

1. Color Fastness: High - quality dyed films have excellent color stability. They do not fade, change color, or become discolored over time, even when exposed to long - term sunlight and various environmental conditions. You can check product reviews or ask for samples to observe the color change after a period of time.
2. Visible Light Transmission (VLT) and Clarity: The VLT value should be within the range that meets your needs. Besides, good - quality films ensure clear visibility, without obvious distortion, haze, or blurriness, allowing for a natural and unobstructed view from the inside.
3. Heat and UV Blocking Performance: Quality dyed films effectively block a significant portion of solar heat and harmful UV rays. Look for films with high - performance heat - blocking capabilities, usually indicated by a low solar heat gain coefficient (SHGC), and those that can block 99% or more of UV rays.
4. Adhesive Quality: The adhesive on the film should be strong enough to ensure firm adhesion to the window surface, preventing the film from peeling or bubbling. At the same time, it should be easy to remove without leaving residue when the film needs to be replaced.
5. Durability and Resistance: Good - quality dyed films are durable, resistant to scratches, abrasions, cracking, and peeling. They can maintain their integrity and performance over a long period, even under the impact of daily use and environmental factors.
6. Thickness and Material: Generally, a certain thickness of the film can provide better performance and durability. High - quality films are made of premium materials, which not only affect the film's physical properties but also its overall quality and lifespan.

Dyed window films are an ideal choice for budget - conscious customers.

They offer an affordable way to enhance privacy, reduce glare, and block some solar heat without breaking the bank. Despite their low cost, they still provide decent functionality, making them a practical solution for those looking to upgrade their windows without a large investment. With various colors and styles available, dyed films balance affordability with aesthetic appeal.

FAQ:

• Q1: What is a primary dyed window film?

  A: Primary dyed window films integrate pigments or dyes into the raw material (PET) during production. The color is added when melting and biaxially stretching the PET, and then an anti - scratch layer or installation adhesive is applied. This is different from surface - dyed or interlayer - dyed films.

   

  Q2: What are the features of primary dyed window films?

  A: They generally offer relatively good color stability as the color is incorporated at the raw - material stage. They can block a certain amount of infrared rays and UV rays, providing some heat insulation and UV protection, which helps reduce indoor heat and protect interior items. High - quality ones also maintain good clarity, ensuring unobstructed views.

   

  Q3: Do primary  dyed window films fade?

  A: Although they have better color fastness, under harsh conditions like long - term direct sunlight, high temperature, or humidity, or if the quality is poor, fading can still occur. Usually, darker colors like black and blue fade more slowly, while lighter colors such as yellow, red, and green may fade relatively faster.

   

  Q4: How to distinguish the quality of primary  dyed window films?

  A: Material: Inferior films use common polyester, being weak, wrinkled, and lacking texture. High - quality ones use optical - grade polyester, feeling thick, smooth, and having high strength. Clarity: Poor - quality films, often with dyes or aluminum plating, have low clarity due to their ordinary base materials. Good - quality ones, with optical - grade bases, offer high clarity. Smell: Inferior films, with poor - quality adhesives and dyes, may emit pungent odors and release harmful substances. Quality films use PSA adhesives with a faint smell. Color: Low - quality films have uneven and unstable colors, easily fading. High - quality films have uniform colors and are more resistant to fading. Scratch - resistance: Inferior films lack anti - scratch layers and may decolorize when wiped with alcohol or gasoline. Quality films have anti - scratch layers and do not decolorize easily.

   

  Q5: What about the heat - insulation effect of primary dyed window films?

  A: These films can absorb a large part of the sun's infrared energy and radiate it on both sides.
