其實嘛...熱傳效果最好的就是水,只是水還有腐蝕或結凍的問題,所以才要添加劑(水箱精)。
那回到GUNK這兩項產品,我們看看原廠網頁不就知道在幹嘛了嗎~

先看看透明罐黃色液體的SUPER COOLANT OPTIMIZER:
http://www.rscbrands.com/products/prodinfo/C1516.PDF
Surfactants in Liquid Kool® Super Coolant Optimizer improve
heat transfer from engine interior to coolant and from coolant to
radiator to improve cooling efficiency in water-cooled engines.
Helps reduce engine temperature, helps prevent overheating,
decreases localized hot spots to reduce “ping,” and provides
corrosion protection. Mixes with all antifreezes/coolants and
protects iron, aluminum, brass from corrosion, including
electrolysis.
這邊自己看吧,大致上就是說改善熱傳避免過熱或熱點,添加在防凍/水箱精裡,保護鐵、鋁、銅不腐蝕及電解(electrolysis)。
但我們依然不知道葫蘆裡賣什麼要,對吧?美國人很怕被告所以都會附上MSDS,其中就有成分啦~

3. Composition/information on ingredients
Mixtures
Chemical name Common name and synonyms CAS number %
ETHYLENE GLYCOL 107-21-1 10 - < 20
Other components below reportable levels 70 - < 80
Borax 1303-96-4 5 - < 10
也就只是乙二醇跟硼砂,剩下八成是水跟顏料吧?那為何會改善熱傳哩?我想樓上前輩有解釋了,只是剛好把部分腐蝕或是結垢物去除掉後的效果。
那白色罐子又在幹嘛?一樣,看資料:

Starts working immediately! Easy to use! Keeps cooling system
cleaner! Prevents acid and corrosion build-up! Great for air
conditioned cars!
馬上用簡單用,保持冷卻系統清潔,防止酸及腐蝕,對冷氣車更讚!
(英文程度不好,隨便翻的請勿見怪,還請前輩指點怎麼翻譯更好看)
但這樣看,這也是在處理腐蝕物。

再來看MSDS:

不copy paste了,一樣是乙二醇跟硼砂啊?新瓶裝舊酒同個成份當兩個產品賣?
但說實在話講,除非把變因都固定去測試,否則很難說是有用還是沒效。另外是冷卻系統正常下,也用不著特地找補品,正常水箱精用下去就好。不過可以參考友板前輩的研究,
