Laboratory Simulation of Sunlight, Heat, and Moisture
BQCIS conducts accelerated weathering using xenon-arc and UV fluorescent devices (ISO 4892, ASTM G155/G154). Test profiles replicate solar UV, visible light, temperature cycling, and condensation/spray to evaluate gloss retention, color shift, cracking, chalking, and mechanical degradation.
Typical applications include coatings, polymers, packaging, building materials, automotive exterior parts, photovoltaics, and consumer goods. Results help engineering teams compare formulations, set specs, and substantiate durability claims.
Key Activities in Accelerated Weathering
Key Benefits of Weathering & UV Testing
Faster Time-to-Insight
Predict long-term durability in weeks, not years, to speed formulation decisions.
Design Confidence
Qualify materials and coatings against OEM, construction, and consumer standards.
Warranty Support
Defensible data to support durability claims and resolve field disputes.
Cost Optimization
Compare alternatives to reduce over-engineering while protecting performance.
Success Story
UV Durability Qualification for Building Façade Coating
An architectural coatings supplier needed proof that a new low-VOC topcoat would retain gloss and color over 10 years in high-UV regions.
BQCIS executed xenon-arc exposures (ISO 4892-2) with periodic ΔE* and gloss measurements, plus adhesion and microcrack checks.
The topcoat met performance targets with <2.0 ΔE* and <10% gloss loss vs. control. Customer used results to win a national façade program.
