Marine & Automotive Grade Fluorocarbon Weathering Technology

Fluorocarbon Clear Heat-Insulating CoatingEngineered for Skylights & Glass Roofs: Heat Stays Outdoors.

Designed for skylights and glass canopies. Weather-resistant fluorocarbon resin, rolled or sprayed on the exterior glass surface, rejects 90%–95% of infrared heat so warmth dissipates outdoors.

IR Rejection
90% – 95%
QUV Test
4,000+ hours

Core Advantages of Exterior Application

1
Heat dissipates outdoors
Indoor films trap heat inside the glass. An exterior coating stops over 90% of infrared before it passes through.
2
No overhead work, no masking tape
Applied while standing on top of the glass roof. No overhead fatigue and no taping of interior frames.

Solar Spectrum Analysis

Blocking infrared (IR) is the real key to heat insulation

Ordinary clear, frosted or tinted glass lets most infrared through. IR (780–1400nm) is the main source of solar heat.

3%
Ultraviolet (UV)
250–400nm. Causes fading and aging. Blocked by the fluorocarbon layer.
43%
Visible Light (VLT)
400–780nm. Keeps interiors bright with natural daylight.
54%
Infrared (main heat source)
780–1400+nm. Our core target: blocks 90%–95% of this heat radiation.

20× Weatherability

Fluorocarbon Resin vs. Standard Acrylic Resin

Exterior coatings face intense solar UV. Standard acrylic cracks after about 200 hours of QUV testing. Our fluorocarbon formula shows only minimal change at 4,000+ hours, about 20× more durable.

Application Comparison

✓ Energy Bear exterior application
  • Simple roller application from on top of the glass.
  • No masking tape; interior frames stay clean.
  • Heat dissipates outdoors before reaching the interior.
✗ Traditional interior film / coating
  • Tiring overhead work with a risk of uneven coats and drips.
  • Masking takes longer than the coating itself.
  • Heat passes through the glass first and is trapped indoors.
