SILAPRENE® M6324 Adhesive/Sealant

Preparation of substrates:

• Surfaces to be bonded should be cleaned of all dust, oils or other contaminates. A solvent wipe is often adequate.
• Bonds to rigid surfaces are usually improved by a solvent wipe followed with light abrasion (180 grit) and solvent wiping to remove abrasive residue. Dry surfaces thoroughly before applying sealant.

Method of application:

• Adhesive/Sealant can be applied by brush, trowel or pressure pumping. Pumping equipment should be of the follower-plate type. Aro, Binks, DeVelbiss, Graco and Lincoln all produce suitable equipment for handling this material.
• Apply a bead of Adhesive/Sealant to one surface at temperatures above 40°F.When used as a sealant, the applied bead will shrink approximately 60% so no tooling is necessary for most applications. The bead surface will be tack free in 15 - 45 minutes, depending on ambient conditions. Initial set time is 4 hours, after which parts may be handled.
• When used as an adhesive between two non-porous surfaces, solvent must escape through the edges of the bond line. Clamping, taping or use of mechanical fasteners to hold parts in place until adhesive/sealant develops strength in recommended.
• After 24 hours at room temperature, the product is considered self-holding. The use of a heat lamp at 150°F for 1 hour will speed solvent evaporation and accelerate strength build-up. An alternative technique is to: apply product to one surface, press the two surfaces to be bonded together to ensure adhesive transfer, separate parts and allow to air dry 10-20 minutes, then press together with good pressure.
• Adhesive/ Sealant M6341 is formulated for room temperature curing, and curing is initiated when a majority of the solvent has been evacuated form the bond line. Strength build-up is very fast in the early stages to give high holing power, with continued strength build-up over time.
