Frequently Asked Questions

MEGA BLACK silicone is a high-flex, moisture curing gasketing material that also offers oil resistance. Today, we see components changing and unlike materials meeting (plastic/steel, aluminum/steel, etc.), all with different rates of expansion and contraction. In addition, with technology advancing, regulations and requirements tightening, we see thinner metals, fewer fasteners, and wider spread bolt patterns. The strength and flexibility of MEGA BLACK handles the changes and added stresses that exist between today’s lightweight, high performance, and premium component assemblies. It is sensor safe, low odor, and non-corrosive with resistance to oil and shop fluids.

Use on newer lightweight and premium components where maximum oil resistance is required. MEGA BLACK is best for assemblies where dissimilar materials meet. Application examples include valve covers, oil pans, oil pumps, intake manifold end seals, and timing gear covers.

MEGA GREY is designed for high rigidity, high torque, and high performance. This feature combination joined with outstanding resistance to oils, coolant, and shop fluids make MEGA GREY one of the most versatile gasket makers available. MEGA GREY resists aging, weathering and will not harden, shrink, or crack. It is sensor safe, low-odor and non-corrosive.

Use on high-torque, high vibration applications, like those common in import & late model engines and component upgrades. MEGA GREY is best for assemblies where high vibration exist. Application examples include valve covers, intake manifold end seals, timing covers, water pump and thermostat housings, Automatic transmission pans, and slip-fit exhaust parts.

All Versachem® products are stamped with a date/batch code number indicating when the product was made. Here’s an example of the date code and how to read it (Example: 9AB1234A01) the first digit is the year 1=2011, 0=2000, 9=2009 etc. and the first letter is the month of the year A=Jan. B=Feb. C=Mar. etc. the next letters and digits is the batch number and the last two digits in the day of the week the product was manufactured 01=1st-31=31st. The example: 9AB1234A01= 9=2009 A=January 01=1st day of month.
