Product Description

LK90C Thermocure Methacrylate Impregnation Sealant (Ultraseal PC504 alternative)

Vacuum impregnation sealants are the permanent solution to porosity in metal casting, filling any voids with a stable yet flexible polymer that is resistant to attack from heat(up to 200°C), oils or chemicals.

LK90C is a good alternative for Ultraseal PC504 Methacrylate Impregnation Sealant, even in some certain applications LK90C showed higher pass rate.

It has become the preferred choice worldwide in sectors ranging from military and aerospace components to high-volume automotive engines.




We not only produce vacuum impregnation sealant but also offer vacuum impregnation equipment and service.
