潤滑矽脂用於潤滑和密封潤滑，這種潤滑脂技術含量較高，能夠生產的企業不多，常用的型號包括:虎頭hotolube的全合成潤滑矽脂: 長城的特221潤滑脂;克魯伯kluber的L 641潤滑脂; huskey的LU221。使用礦物油，由於礦物油黏度高容易沾染塵士。也不一定宜使用鉛筆未或黑色石墨潤滑，不可以潤滑到內部部件，而且會有重金屬和顏色污染。
汽車門鎖包括鎖芯、鎖體、內開把手、外開把手、內鎖止機構、拉杆、鎖門、鎖扣等，需要潤滑的部件很多，應使用特殊性能的潤滑脂，性能如下:
1、長效性，門鎖機構封閉在車門內，不易保養，潤滑脂應具有長期甚至終生潤滑效果
2、耐低溫，必須滿足-40度的低溫潤滑性，冬季不會凝固和凍結，影響鎖機構的運動;
3、耐水性和防銹性，車門並不是封閉結構，潤滑脂應具有良好的耐水性和防止繡蝕:
4、因此，這種車鎖機構的潤滑不能採用普通的理基潤滑脂或者其他礦物油生產的潤滑脂，應使用合成基礎油生產的全合成潤滑矽脂或全合成氟素脂。套保有130克牙膏管包裝，效果很好.

This type of grease has a high technical content and not many companies are able to produce it, commonly used models include: Tigerhead hotolube's fully synthetic grease, Great Wall's Special 221 grease, Kluber's L 641 grease, huskey's LU221. It is not always advisable to use pencil grease or black graphite grease, which cannot be used to lubricate internal parts and can be contaminated with heavy metals and colours.
Car door locks include the lock core, lock body, inside opening handle, outside opening handle, inside locking mechanism, pull rod, locking door, latch, etc. There are many parts that need to be lubricated, so special performance grease should be used, the performance is as follows.
1、Long-term effect, the door locking mechanism is enclosed in the door, not easy to maintain, the grease should have a long-term or even lifelong lubrication effect
2、Low temperature resistance, must meet the -40 degrees low temperature lubrication, winter will not solidify and freeze, affecting the movement of the lock mechanism.
3、Water resistance and rust resistance, the door is not a closed structure, the grease should have good water resistance and prevent embroidery.
4. Therefore, the lubrication of this type of locking mechanism should not be carried out with ordinary lubricating greases or greases made from other mineral oils, but with fully synthetic silicone greases or fully synthetic fluorocarbon greases made from synthetic base oils. The set comes in a 130g toothpaste tube and is very effective.
