Application
Application: For uniform mixing, cement containers should be agitated or drums rotated before the addition of hardener. Thoroughly mix the appropriate amount of hardener (8% by weight) into the cement at 21oC. This mixture will give you an application life of 6-8 hours before cross-linking.

Specific application sheets are available for the following:

1. Bonding rubber sheeting to steel.
2. Bonding urethane sheeting to steel.
3. Bonding urethane sheeting with bonding layer to steel.

Rubber to Steel: Metallic surfaces must be free of oils, grease or other contaminants. Rust and mill-scale should be removed by sand blasting to NACE #2. A profile of 2-3 mils is preferred. The rubber, if cured should have all mould release agents removed and buffed with 24 grit or stiff bristled wire brush at a speed as not to burn the rubber surface. Apply a first coat to each surface with a scrubbing-like motion. Allow this coat to dry for at least 1 hour at 21oC. Should the ambient temperature be lower, allow a 50% increase in drying time for every 3oC drop in temperature. After the required drying time a second coat is applied to each surface in a manner as not to disturb the primary coat. Let dry until tacky, adhere both surfaces and stitch down or apply pressure. The maximum bond strength will develop to its optimum in 21 days, however, initial bond strengths will be sufficiently high after 6 hours and are ready for most services.

Rubber to Rubber: The rubber, if cured in sheet form should be solvent cleaned and buffed as described above before the first coat of adhesive is applied. Allow the first coat to dry for at least 1 hour or longer. Should the temperature be lower, better adhesion will be achieved by increasing the first coat's drying time by 50% for every 3oC drop below ambient. After the required drying time a second coat is applied and when still tacky, stitch the two components together or apply pressure.

Rubber to Other Substrates: For adhering other elastomeric materials or special environmental conditions, please contact our main office. Trials, if possible are recommended before production to determine the suitability of this compound with individual materials and to determine the preferred method of application.
