Patent #'s 10525627 and 10220559
This variation of hollow gasket dispensing offers a direct replacement for traditional solid gasket dispensing.
Hollow gaskets in this category offer:
1) Greatly reduced material usage
2) The effective force of compression is far less than it would be for an equivalent solid gasket.
3) For many RTVs and UV cure silicones, the cure time is reduced and intensity requirements are also reduced.
Small and large gaskets were done in Novagard 400-150, an oxime moisture cure RTV.
