Sealant provides higher tensile strength

Fabrication logo Specially formulated for automated assembly, new Dow Corning HM-2520 assembly sealant combines the immediate green strength of a hot melt adhesive with the long-term performance of a reactive silicone sealant. It also offers improved resistance to movement during cure and at high temperatures under load. This sealant is a neutral-cure, low-VOC sealant that enables parts to be moved immediately upon application.

The sealant maintains excellent adhesion to most common substrates. It has a high tensile strength of 700 psi and service temperatures ranging from -50° to 300° F (-45° to 150° C). This product meets FDA Regulation CFR 177.2600 and is NSF 51 and NSF 61 listed.
