Light Stabilizers Make the UV Protection of Environmental Friendly Coatings Easier

25-Apr-12 09:27

High solids, powder, waterborne and UV curable coatings-the “green” coatings-have been developed to replace conventional high VOC and solvent-based coatings. Although the latest technology has overcome the disadvantages of traditional solvent-based coatings, light stabilizers in green coatings still play an important role helping to avoid degradation from sun light exposure and improve weathering stability. Everlight has developed several products specifically for green coatings.

Lignin, when exposed to sunlight, can easily be degraded. Results from a study, carried out by Everlight, suggest when wood was treated with high performance light stabilisers prior to the application of a clear coat, can extend the protection of lignin from UV light degradation

光安定劑於光電元件之應用

06-Oct-11 14:01

許多光電元件(包含光電顯示器及太陽能光電相關元件)均以高分子材料為主體，而這些材料容易因環境因子，如光、熱、氧所破壞，致使材料發生裂化、黃化或粉化等現象。由於光電元件的品質要求愈來愈嚴苛，故本文針對...

高性能水性複配型光穩定劑應用於南方松表面處理

木質素受到陽光照射下很容易劣化，要保留天然木器紋路和顏色的外觀，目前工業界常用的方式是在木器的表面塗上一層保護的清漆，這層保護作用的來源主要是添加紫外線吸收劑(UVA)和受阻胺光穩定劑(HALS)來達成，但是這種塗佈方式的保護效果比較有限，根據實驗結果顯示，如果在塗佈清漆之前，先將木器的表面做一種防止老化的處理，它就可以更有效的延長保護時間。
