Experience how a truly state-of-the-art, eco-friendly, razor-thin layer of nanotechnology can save you money & keep you safer.

Any time your vehicle's windshield is compromised by weather conditions or debris, it puts yours and your passengers' safety at risk. ExoShield extends the life of your windshield by integrating state-of-the-art nanotechnology onto your vehicle to help you avoid costly and time-consuming windshield replacements.

ExoShield is a thin, transparent film applied on the exterior surface of a windshield, just like automotive tint. The state-of-the-art nanomaterials behind ExoShield increase a windshield's impact resistance by 6 times and block 99.9% of harmful UV radiation. ExoShield films can prevent stone chips, improve visibility, block UV radiation, prevent frost, and reduce cabin heating.

Alchemy is based in Canada and is a Y Combinator alumnus.
