Metal adhesives

NuSil MED-2000 Silicone, One part Adhesive - Unrestricted Medical Use
Categories: Polymer; Adhesive; Thermoset; Silicone

Material Notes: Description: Silicone adhesives are elastomers or pressure sensitive adhesive systems that are designed to bond silicone surfaces to each other and to other substrate surfaces such as metals and plastics. There are one-part and two-part adhesives, ranging in consistency from flowable to non-flowable (non-slump). Silicone primers are specially formulated silanes supplied in a solvent that are used to improve the bond strength between a silicone elastomer or adhesive and another substrate surface (silicone, metals, and certain plastics).

Important Properties of Adhesives: In general, silicone adhesives adhere well to substrates such as glass, aluminum, titanium, other silicones, and some ceramics. While various types of materials can be used as adhesives, silicones are consistently chosen for their many inherent properties and overall versatility. Advantages of these adhesives are as versatile as silicone itself:

  • Proven biocompatibility
  • Resistance to moisture
  • Ability to remain elastic at temperatures below 0 ºC
  • Ability to resist chemical breakdown at temperatures >200 ºC
  • Low modulus prevents warpage, delamination and substrate failure.
Comments: Self-Leveling

Cure System: Acetoxy
