Description
The 3M CR70 is a high-performance, nearly clear automotive window film from 3M’s Crystalline series, known for excellent heat rejection (around 60% total solar energy) and significant infrared (IR) blocking via nano-ceramic tech, while allowing high visible light transmission (around 70%) for clear visibility, making it ideal for windshields to reduce glare and heat without looking dark or interfering with electronics. It blocks nearly all UV rays, improves AC efficiency, and offers privacy without dark tint.
Key Features & Benefits
High Heat Rejection: Rejects a large percentage of total solar energy and infrared (IR) heat, keeping your car cooler.
High Visibility: It’s a light, clear film (around 70% Visible Light Transmission) that offers excellent night vision and reduces glare without compromising sight.
UV Protection: Blocks up to 99.9% of harmful UV rays, protecting skin and car interiors.
No Signal Interference: Its metal-free, nano-ceramic design ensures no interference with GPS, mobile phones, or other devices.
Improved AC Efficiency: Reduces the load on your car’s air conditioning system, saving fuel.
Privacy: Provides privacy by blocking views into the car, though it’s not a dark tint.
Application & Usage
Ideal for Windshields: Often applied to front windshields (and sometimes side windows) to tackle the most intense solar heat and glare.
Legal Compliance: Its high VLT (Visible Light Transmission) often keeps it within legal tint limits in many regions.
Cost: A premium product, with pricing varying by vehicle and installer, but generally more expensive than basic films.
In essence, the “CR70” signifies the Crystalline series (CR) with 70% VLT, focusing on performance, clarity, and advanced heat-blocking 
technology.
