    How to use

    Substrate preparation

    All surfaces must be clean and dry. Degrease and wash off any impurities that may: impair adhesion. Suitable solvents include isopropyl alcohol, acetone or methyl ethyl ketone.

    Good unprimed adhesion can be achieved on a variety of substrates including enamelled and painted steel, aluminium, ceramics, glass and some plastics.
    Substrates to which good adhesion is not usually obtained include PTFE, polyethylene, polypropylene and related materials.

    DOWSIL™ 1200 OS Primer is recommended for maximum adhesion. Apply a thin layer of primer by dipping, brushing or spraying. Allow the primer to dry for 15 to 90 minutes at room temperature and a relative humidity of 50% or higher.

    Method of application

    Apply a coat of DOWSIL™ 7091 Adhesive Sealant to one of the prepared surfaces, then quickly coat with the second bonded substrate.
    After exposure to moisture, the freshly applied material "skin" after about 10-15
    minutes at room temperature and 50% relative humidity. All tooling should be completed before this skin forms. The surface is easily treated with a spatula. The adhesive/sealant will dry in approximately 30 minutes.

    Curing time

    Once the skin is formed, curing continues inward from the surface. In 24 hours. DOWSIL™ 7091 Adhesive Sealant will cure to a depth of approximately 2mm. Curing time will be longer at lower humidity levels and with very deep joint sections. Before transporting and packing glued components, it is recommended that users wait a sufficient amount of time to ensure that the integrity of the adhesive is not compromised.
