The products in the ThreeBond 2300 and 2400 series are based on a technology developed to meet highly sophisticated requirements. The process is a special coating process in which resins are applied to the threads of screws or bolts replacing the need for liquid anaerobics, sealing tapes or liquid sealants.

In the MEC process, a microencapsulated, highly reactive sealing and locking agent is applied to the threads of screws, bolts, or pipes. The agent does not react until the part is tightened; then the microcapsules break, and the sealing and locking agent instantly polymerizes to prevent loosening or leaking.

ThreeBond 2403 is microencapsulated acrylic precoat for use as a locking and sealing agent on screws or bolts. Material exhibits low friction on fastening.

ThreeBond 2411 is microencapsulated acrylic precoat for use as a locking and sealing agent on screws or bolts. Low strength .

In the MEC process, a microencapsulated, highly reactive sealing and locking agent is applied to the threads of screws, bolts, or pipes. The agent does not react until the part is tightened; then the microcapsules break, and the sealing and locking agent instantly polymerizes to prevent loosening or leaking. After MEC processing, no locking agent or sealant needs to be applied to threads; the sealing and locking properties are activated in the assembly.

ThreeBond 2415 is microencapsulated acrylic precoat for use as a locking and sealing agent on screws or bolts offering medium strength high temperature resistance.

ThreeBond 2471 is microencapsulated acrylic precoat for use as a locking and sealing agent on screws or bolts offering medium strength and low residue for use on bowl feed systems

ThreeBond 2440B is a microencapsulated high strength epoxy precoat for use as a locking and sealing agent on male and female threads.

ThreeBond 2363 is microencapsulated nylon precoat for use as a locking and instant sealing agent on screws or bolts offering medium strength and re-usablility.
