An extensive on site laboratory performs two key functions: one deals with quality checks on raw materials and monitors production, in addition to testing samples of customers' sealants when required. The other concentrates on the research and development work crucial to the implementation of new products to meet future requirements, and to maintaining Ultraseal's world leading position in the impregnation industry.

Ultraseal International's extensive sub-contract impregnation experience over three decades has equipped the company with unique and unrivalled expertise in meeting the requirements of customers in all sectors needing to treat porosity.

This has enabled the company to develop bespoke products for specific applications demanding additional performance or where the nature of the components themselves renders standard impregnation methods inappropriate.


SINTERSEAL 100

Nowhere is this better illustrated than by Ultraseal's development of Sinterseal 100, a sealant specifically for the powdered metal industry. Traditionally, cast components are impregnated to seal them against leaks, which if left untreated would cause them to fail in service. Sintered parts, from the Powder Metal industry, have different properties that require impregnation for one or more different reasons.


Increased Machinability

Powder Metal components are notorious for their aggressive affect on cutting tools. Impregnation prior to machining effectively creates a more homogeneous surface thereby reducing potential for tool "chatter". This can result in extension of tool life by up to 100 times.


Surface coating pre-treatment

The significant porosity in powder metal parts can harbour contaminates such as oil, acids or cleaning agents, from production processes. If left untreated, this can lead to subsequent surface treatments being damaged when these contaminates leach out to the surface. Impregnation effectively cleans and fills this porosity allowing a better quality surface treatment thus ensuring increased life expectancy.


Pressure Integrity

In applications where powder metal parts are used for pressure critical components, impregnation ensures that the inherent porosity within the part is fully sealed, therefore ensuring it is fit for purpose.
