ATO dispersion achieves 0.2–0.3% haze in PVB, validated by Tier-1 interlayer partner
A Tier-1 PVB interlayer manufacturer
Key metrics
01
The challenge
The Tier-1 PVB interlayer partner needed an ATO dispersion for solar heat control interlayer film that could achieve automotive-grade haze (<0.5%) when laminated with green glass. Previous ATO suppliers using top-down ball-milling produced dispersions with haze exceeding 1.7%, far above automotive requirements.
02
Our approach
Kriya provided four ATO dispersion variants at 8.3 wt% concentration for evaluation. The partner laminated samples with 2.0 mm green glass and measured optical properties including visible light transmission, total solar transmittance, and haze according to their internal automotive qualification protocol.
03
The outcome
The optimised variant achieved 0.2% haze at 0.10 wt% and 0.3% haze at 0.20 wt% in PVB—the only samples passing the partner’s automotive haze threshold. Visible light transmission ranged from 71–75%, and total solar transmittance from 58–61%. The partner concluded the technology had "great potential."
Why Kriya
Kriya’s proprietary bottom-up ATO synthesis produces nanoparticles with fundamentally lower scattering than ball-milled alternatives, achieving 5× better effectiveness at equal SHGC versus the leading competitor.
