The bond for screen printing

The BOND is a two-component, low-viscosity frame adhesive for High Mesh Tension screens and fast drying requirements. It has excellent chemical resistance and adhesion to all commonly used screen frames. Its low viscosity makes it most suitable for finer mesh counts. Drying time before can be cut away from stretcher is approximately 5 minutes.
Excellent mesh adhesion and encapsulation properties, durable printing.
Excellent solvent resistance and easy to reclaim, extended re-use of screen mesh.
Superb resolution and sharp image definition for the fine image reproduction.

Product Description
RSKG Bond is a fast drying, two component frame adhesive for high tensioned mesh. It has excellent chemical resistance and adhesion to all commonly used screen frames. 
2.1. Frame preparation Before adhering the mesh with RSKG Bond, remove excessive adhesive residue from the frame with PREGAN DL, grinding or sandblasting. Be careful not to roughen the frame surface too much, as this could impair the adhesion of the adhesive. Frames should be free from oil, grease, dirt, water and solvents before applying the adhesive. Slight residues of RSKG Bond, however, do not need to be removed. The surface should be even. If the frame surface is slightly uneven or has deeper grooves from sandblasting or grinding a pre-coat of RSKG Bond T with hardener can be used to even the surface. 
2.2 Mixing the adhesive. Before use, mix RSKG Bond A with parts of RSKG Bond B. For higher solvent resistance and for pre-coating of the frame, the ratio of hardener can be increased. However, when increasing the amount of hardener the adhesive becomes more brittle. 
2.3. Applying the adhesive Using pressure apply the adhesive with a short bristle brush or scraper-type applicator onto the bonding area of the mesh. Make sure that a sufficient amount of adhesive is worked through the mesh and obtains contact with the frame. Bubbles showing through the mesh indicate poor contact between mesh and frame. 
2.4 Curing / Drying time The adhesive dries in about 3-7 minutes depending on application thickness and room temperature. After approximately 3-7 minutes the frame can be cut away from the stretching unit. After 3-4 hours the adhesive is relatively resistant to solvents and water and over-lacquering or degreasing is possible. The complete chemical resistance is achieved after 24 hours.
 2.5 Protective lacquers If the frames are used in automatic screen washing units or if the adhesive has prolonged contact with solvents, over lacquering with Estelan AR is recommended.
