普通硅橡胶为什么不可用作机电产品的密封材料?
1. 普通室温硫化橡胶(有醋酸味道)不能用来密封封闭系统如齿轮箱,电器箱等.因为乙酸固化会腐蚀内部机件如轴承,接触器等.乐泰硅橡胶则无此缺点
2. 普通室温硫化硅橡胶(有醋酸味)不能用来密封工作温度较高的润滑油系统如油底壳等.它会被溶胀并失去密封能力.乐泰硅橡胶则无此缺点
3. 普通室温硫化硅橡胶(有醋酸味)高挥发性不能用于传感器附近.因为它在固化时释放出的微粒会包住传感器而使传感器失灵.乐泰硅橡胶则无此缺点
4. 普通室温硫化硅橡胶(有醋酸味)不能用来密封燃油系统.它会被溶胀并失去密封能力.乐泰硅橡胶或厌氧胶则无此缺点

◆Loctite Corporation began in the Trinity College basement laboratory of Dr. Vernon Krieble of Hartford, Connecticut in 1953. This entrepreneurial chemistry professor developed a cure inhibition system for a unique bonding resin that hardened in the absence of air- an anaerobic sealant.
 
Loctite? made its official public debut at a press conference at the University Club in New York on July 26, 1956. The promise of solving the age-old problem of loose nuts and bolts in machines and appliances – a problem customers had long ago accepted as unsolvable – led to an incredible flow of inquiries.

In the 1960s, cyanoacrylates – also known as CA or “Superglue”, a very fast, one-part, room-temperature curing type of industrial adhesive – were added to the Loctite? brand. Silicones, epoxies, acrylics and the development of further generations of Loctite? anaerobics and cyanoacrylate technology and products followed.

Throughout its history, Loctite? has continuously created markets by discovering opportunities where no one knew they existed. From its founding, based on a product that solved an "unsolvable" problem, Loctite? has achieved success through innovation.

In 1997 Loctite has been acquired by Henkel and remains a primary brand.
