Dam & Fill and Glob-Top

The Dam & Fill combination allows for coating a specific area within a set of components. The PROTAVIC line includes products with high glass transition temperature and low coefficient of thermal expansion.

Dam & Fill protects sensitive components by providing resistance to thermal and environmental stress.

Glob-Top coatings offer the same protections for smaller chips.

Through a diverse product line with a range of chemical and physical properties, PROTAVIC covers all possibilities.

Some examples are listed in the table below.
