NuSil™ MED-1137 Features & Benefits

Labeling Claims
Ready to Use Product Features
Product Highlights
  • One part, low slump, solvent-free translucent silicone
  • Cures at room temperature upon exposure to atmospheric moisture

Applications & Uses

Applications
  • Well suited for use as an adhesive for bonding and sealing silicone materials
  • For applications requiring the bonding of silicone to metals, urethanes and various other substrates
Instructions for Use

Apply MED-1137, supplied in cartridges, with the use of appropriate dispensing equipment. Do not store alcohols near the worksite as traces of alcohol inhibit the adhesive’s catalytic system.

Surface Preparation

Thoroughly clean surfaces being bonded or built-up with silicone adhesive using a non-oily cleaner or mild soap to remove any surface contaminants. Do not use synthetic detergents or oil-based soaps, as they may be absorbed and subsequently leach out. Rinse first with hot water, followed by a thorough rinse using distilled water. Use compatible degreasers to clean metal surfaces.

Bonding Applications

Spread a layer of silicone adhesive on one of the surfaces. Squeeze both surfaces together to bond. Apply sufficient pressure to ensure full contact without forcing the silicone adhesive from between the pieces. Note: Some bonding applications may require the use of a primer. NuSil Technology’s MED-160 is recommended. For more information on primer selection, visit www.nusil.com and review Choosing a Silicone Primer/Adhesive System.

Curing Time

Curing or vulcanization time depends upon the thickness of the silicone adhesive layer, relative humidity, and accessibility of atmospheric moisture to the curing adhesive. For sections of typical thickness, a relative humidity level between 20-60% is recommended to cure the adhesive at room temperature. Generally the adhesive forms a thick, tack-free outer skin for thick section films within a few minutes after application. The vulcanization rate slows when exposing very thin films to excessive humidity (80% relative air humidity). For films below 80 microns, the relative air humidity should be within 30% - 50%. Because MED-1137 cures upon exposure to atmospheric moisture, keep tubes tightly closed when not in use. A plug of cured material may form in the tip of the tube. Remove or dispense the plug from the tube before using.
