Does Tint Get Darker as it Cures? Find Out Here!

Window tinting is a popular automotive customization option offering both functional and aesthetic benefits. However, as a car owner, you might be willing to know more about the tinting process.

One common query is whether tint gets darker as it cures. This is an important aspect to consider, as it can affect the final appearance and performance of the tinted windows.

Let’s find out more about this in this article.

Does Tint Get Darker As It Cures

 

What is tint curing?

Tint curing refers to the process by which the adhesive in window film sets and bonds to the glass. This can take anywhere from a few days to a few weeks, depending on factors like temperature, humidity, and the type of tint used.

As the tint cures, its appearance may indeed change slightly, with some tints darkening marginally while others remain the same or even lighten.

Understanding the factors affecting tint darkening and the curing process can help you make informed choices about your window tinting project.

Tint Curing Process

The curing process involves a chemical reaction between the tint’s adhesive and the car window. This reaction helps the tint stick to the window and lasts for a specific period.

After applying the tint, drying is essential to remove any remaining moisture. Moisture may cause bubbles or hazy appearance, which usually disappear as the tint cures.

The darkness of the tint can change during the curing process but does not necessarily darken significantly. The final darkness depends on the original tint shade and the adhesive’s chemical reactions.

Factors Affecting Tint Darkening

Check out the factors affecting the extent of tint darkening.

Type of Film

Different types of window tint films can alter how the tint appears after curing. For example:

  • Dyed films: May not darken significantly as they cure.
  • Ceramic films: Often display more stable color, not darkening as much during the curing process.

Weather and Climate

Weather conditions and the climate can influence the curing and darkening process. Factors to consider include:

  • Temperature: Higher temperatures can speed up the curing process, while colder temperatures can slow it down.
  • Humidity: Higher humidity levels can prolong the curing time.

VLT Percentage

The visible light transmission (VLT) percentage refers to the amount of light that can pass through the tint film. A lower VLT percentage implies a darker tint. For example:

  • 5% VLT: Very dark tint, allows only 5% of light to pass through
  • 50% VLT: Lighter tint, allows 50% of light to pass through

Installation Techniques

Proper installation techniques ensure that the tint reaches its intended shade as it cures. Factors to consider include:

  • Using the right amount of adhesive is crucial. Too much or too little adhesive can affect the final appearance of the tint.
  • Giving the tint enough time to dry and cure is equally important. Rushing through the process may result in uneven darkening.

While tints may appear to darken as they cure, this is primarily due to the adhesive curing and not the tint film itself changing in color.

Appearance of Tint After Curing

Color and Shade

  • Light tints: After curing, the color becomes more uniform and fine.
  • Dark tints: Mostly appear opaque, as they start setting in.

For example, a newly tinted window can appear lighter and have an “off” shade. But as the tint cures, the shade settles in, getting closer to its intended appearance.

Darkness Level

The darkening process mostly depends on the kind of tint being used and can vary. It is important to note that tint does not necessarily get darker as it cures.

The apparent change in darkness is due to the curing process, where the adhesive sets in, rather than actual darkening.

Tint TypeInitial DarknessAfter Curing
LightLighterMore uniform
DarkOpaqueSettled, even

Visible Light Transmittance

Visible Light Transmittance (VLT) refers to the amount of visible light passing through the tint. With curing, the VLT can appear to change as the tint settles and becomes more cohesive due to the adhesive bonding.

A few things to keep in mind:

  • Bright sunlight: VLT can appear higher than intended during the curing process.
  • Ticket: VLT may affect legality of tint in your area.

Keep in mind that the actual VLT may not change as the tint cures, but the appearance of the tint can become more uniform and consistent.

Benefits of Tint Curing

  • Driving comfort: Tint curing helps reduce glare, providing more comfortable driving conditions.
  • UV protection: A cured tint can block harmful UV rays, protecting the skin and keeping the vehicle’s interior from fading or cracking.
  • Increased privacy: Darker, cured window tints provide a greater level of privacy for vehicle occupants.
  • Theft deterrence: Enhanced privacy can deter potential thieves who might be scouting for valuable items inside the car.
  • Heat reduction: Cured tints reflect heat, keeping the car interior at a more comfortable temperature during hot days.
  • Energy efficiency: With a stable interior temperature, the car’s air conditioning system doesn’t work as hard, leading to reduced fuel consumption.
