Compatibility of VpCI-377 with Gaskets

Background: FAIP would like to utilize VpCI-377 and their gaskets would be exposed to this product during application. FAIP would like to determine if there would be compatibility issues between VpCI-377 and their gaskets.

Purpose: Determine if VpCI-377 is compatible with gaskets.

Materials: VpCI-377

Gaskets provided by FAIP

Methanol

Method: Compatibility Testing

Procedure: The following procedure was performed:

5 gaskets were chosen and the following samples were created:

Sample	Pretreatment	Coating	Concentration of Coating
A	None	VpCI-377	10% by weight
B	None	VpCI-377	50% by weight
C	None	VpCI-377	Neat
D	Water Rinse	------	DI water
E	------	------	------

The samples were inspected, weighed, and this data was recorded.
The samples were dipped in varying concentrations of VpCI-377 and then placed in a 40° C oven for 24 hours.
After 24 hours the samples were removed from the oven and rinsed with methanol to remove any VpCI-377 from the surface.
The washers were reweighed and inspected for any noticeable physical changes.
This information was recorded and a report was written.

Results: VpCI-377 did not change the appearance, feel, or have a noticeable affect on the gaskets. The following Δm was found:

Sample	Initial Mass (grams)	Final Mass (grams)	Δm (grams)
A	1.3852	1.3854	0.0002
B	1.3847	1.3880	0.0033
C	1.3807	1.3997	0.0190*
D	1.3824	1.3812	(0.0012)
E	1.3869	1.3839	(0.0030)

* = this part was not totally clean of VpCI-377

Conclusion: The Δm of the washers was negligible, and the physical appearance and properties of the gaskets did not appear to change. This would lead to the conclusion that VpCI-377 did not affect the gaskets and the two components are compatible.
