SealTek is a pre-applied process which adheres a line of acrylic-based sealing materials manufactured by ND Industries to the underhead of fasteners. SealTek processed fasteners negate the need for additional O-rings, gaskets, or sealing washers. When the fastener is installed, SealTek conforms to surface dimensions and fills voids between mating parts, forming a robust seal.
During the SealTek pre-application process, ND Industries precisely dispenses then heat or UV cures the selected material onto customer provided fasteners. The result is a self-sealing fastener which is dry to the touch and ready for immediate installation. SealTek processing is compatible with a wide variety of parts for use in functions such as:
• Cushioning • Insulating • Masking • Sealing • Trimming • Controlling Noise • Reducing Vibration
SealTek processed fasteners provide an immediate positive seal of up to 500 psi which eliminates leaks while filling voids between mating parts.
Pre-Applied SealTek is compatible with ferrous and non-ferrous metals including a wide range of common fastener finishes.
Unlike O-rings and nylon washers which are difficult to seat, tear easily and lose integrity when nicked or cut, SealTek processed fasteners are easy to seat and perform consistently.
Materials pre-applied with the SealTek processing offer weatherability and dielectric strength while providing excellent fire, chemical, abrasion, UV, and ozone resistance.
SealTek’s pre-application process creates three dimensional cross-linked materials which resist a wide variety of chemicals including gasoline, oil, diesel fuel, alcohol, kerosene, and hydraulic fluids.
The materials selected for Pre-Applied SealTek exhibit an extended shelf life and will not dry or shrink with exposure to the environment.
