SealTek™ 1120
SealTek 1120 is a medium viscosity, cure in place gasket. This system forms a resilient, soft and flexible gasket that can conform to almost any dimensional surface. It will cure rapidly with heat or UV radiation to produce a material with excellent chemical, heat, and moisture resistance. SealTek 1120 replaces the need for in-house the assembly of O-rings and Gaskets.
Features:
- One part system
- Excellent Automotive chemical resistance
- Dual cure system
- Good adhesion to materials including aluminum, steel, and other metals and plastics
- Forms to complex dimensions
- Reusable
