Scope of application
|
For the adhesive bonding and installation of wall and ceiling coverings, noise protection boards made of foam, mineral or wood fibre as well as plaster ornaments and decorations in interior areas. For the bonding of thermal insulation boards made of polyurethane or polystyrene (EPS/XPS) in ventilated facades, installation of window sills, door thresholds, skirting boards. <Ground floor cladding made of wood, wood-based materials, metal, etc. on concrete, masonry, metal or wood in interior and exterior areas. Bonding of small-surface mirrors and coated glasses indoors, provided that no large expansions are to be expected.
|
|
Determination of the amount of adhesive
|
The layer thickness of the adhesive depends on the application, the substrates to be bonded and the thermal and/or physical effects on the bond.<br> For outdoor applications the recommended minimum layer thickness is 3 mm. In the interior as well as for constructions which are powder-coated after bonding, a layer thickness of 2 mm is required. A minimum layer thickness of 1.5 mm should never be undercut.
|
|
Processing
|
Substrates must be load-bearing, solid, dry and free of dust, oil and grease. In order to ensure the necessary layer thickness, the pre-assembly of a one-sided adhesive spacer tape (e.g. GYSODistantband PE-30) with appropriate thickness is recommended in the area of the intended bondings.
|
|
Primer
|
On porous, absorbent surfaces, pretreatment of the substrate with GYSO-Polyflex Primer 414 is recommended.<br><br> On plastics (GFK, ABS, PVC), adhesion tests must always be carried out before application. To improve adhesion, plastics can be pre-treated with GYSO-Polyflex Primer 416.<br> Due to the large variety of powder coating systems, colors, degrees of gloss, etc., no generally binding statement can be made on powder coatings with regard to pretreatment for bonding. In any case, adhesive tests must be carried out. If the adhesive strength is sufficient, no further pre-treatment apart from degreasing is necessary. If the adhesive strength is insufficient, it can be improved by pretreating the substrate with GYSO-Polyflex Primer 418 or by removing the top layer of the powder coating.<br><br>When handling primer, it is essential to observe and adhere to the flash-off times specified on the containers.
|
|
Assembly
|
Apply the adhesive in beads at right angles to the substrate using the V-nozzle supplied (yield approx. 6.50 m/pa.) Join the parts to be joined within 15 minutes and press on.<br><br>Always ensure good ventilation between the parts to be joined. In case of subsequent powder coating, a curing time of at least 7 days must be observed. The baking parameters 180 °C/30' must be observed as far as possible, higher temperatures may cause lasting damage to the bond even with shorter baking times.<In order to avoid air pockets in the adhesive during processing with compressed air guns, only tools with a feed rod such as aB. GYSO compressed air pistol G-88 can be used.<br><br>If necessary leaked adhesive before the skin formation with GYSO smoothing agent N or relaxed water.

Cleaning
|
Impurities can be removed in the fresh condition with GYSO-Reiniger 2000, GYSO-Acrylac Reiniger 2000 or with GYSO-Sol
|
|
Special
|
Do not use below + 5° C. Do not use below + 5° C. When installing overhead, always secure the bond mechanically. With large-surface mirrors and coated glasses with more than 1 m outer dimensions, cracks can occur in the coating due to material expansion.<br> Due to its high Shore A hardness, GYSO-Polyflex 466 is not suitable for expansion joints.<In order to avoid air inclusions in the adhesive during the processing with compressed air guns, tools with feed rod should be used exclusively, e.g. GYSO compressed air gun G-88. The baking parameters 180 °C/30' must be observed as far as possible.
