Although it is more shatter-resistant, it is more expensive than acrylic, yellows with prolonged exposure to sunlight, and is much more easily scratched. A: While acrylic softens at higher temperatures, it does not actually melt until it reaches 320 °F (160 °C).
The answer is no, dried acrylic paint will not melt in the sun if you’re painting outside or have an outdoor painted project. However, they can be affected if for example you leave them in a really hot car, since that changes the heat chemicals of the wet paint.

Can acrylic paint be left in a hot car?
Freezing yes, it was not good for a few paints I left in my garage last winter. 72-75F isn’t actually hot, so it shouldn’t affect them at that temp, but in your car it would have been much hotter. They definitely do soften in heat and I’ve had some stick together when (mistakenly) placed face to face before a show.
Is it OK to let paint dry in the sun?

Can you use a hairdryer to dry acrylic paint?
* You can use a hair dryer to speed dry the paint. * Acrylics can be painted on just about anything including canvas, paper, wood, ceramic, fabric, Masonite, plexiglass, fiberglass and glass. Adding a drying retarder or an acrylic medium will slow down the drying time and keep the natural glossiness.
Does humidity affect acrylic paint?
Humidity affects not only the drying of acrylic and latex paints but also that of oil-based paint. The increase of moisture in the air causes the water in acrylic or latex paint to take longer to dry. This means the water within the paint cannot evaporate as readily.
What are the disadvantages of acrylic?
Disadvantages of Acrylics: The first disadvantage of using acrylics is that it scratches more easily than glass. As compared to most other synthetics, acrylics are less strong and are not resistant to matting. The other not so good thing about acrylics is that they are easily stained by grease and oil.
Does plexiglass hold heat?
