LORD Chemosil® 511 elastomer bonding agent is a
one-coat bonding agent used to bond silicone (MVQ)
and fl uoroelastomers (FKM) to metal and a variety of
other substrates during the vulcanization process.
Features and Benefits :
- Versatile - can also be used as a primer in combination with Chemosil 6025 or Chemosil 231 G bonding
agents to bond a wide range of elastomers to fabrics.
- Easy to Apply - applies easily by brush, spray or dip
methods.
Application :
- Surface Preparation - Thoroughly clean metal
surfaces prior to adhesive application. Remove
protective oils, cutting oils and greases by solvent
degreasing or alkaline cleaning. Remove rust, scale
or oxide coatings by suitable chemical or mechanical
cleaning methods.

- Chemical Cleaning :
Chemical treatments are readily adapted to automated metal treatment and adhesive application
lines. Chemical treatments are also used on metal
parts that would be distorted by blast cleaning or
where tight tolerances must be maintained. Phosphatizing is a commonly used chemical treatment
for steel, while conversion coatings are commonly
used for aluminum.
- Mechanical Cleaning :
Grit blasting is the most widely used method of
mechanical cleaning. However machining, grinding
or wire brushing can be used. Use steel grit to blast
clean steel, cast iron and other ferrous metals. Use
aluminum oxide, sand or other nonferrous grit to
blast clean stainless steel, aluminum, brass, zinc
and other nonferrous metals.
For further detailed information on surface preparation
of specifi c substrates, refer to Chemlok/Chemosil
Adhesives application guide. Handle clean metal
surfaces with clean gloves to avoid contamination with
skin oils.
