PanelTack HM. for the bonding of SVK Ornimat SKG

Transcription

1 PanelTack HM for the bonding of SVK Ornimat Product Simson PanelTack HM is a moisture curing, elastic adhesive based on SMP (Silyl Modified Polymer). PanelTack HM is solvent- and isocyanate free. s Bonding Ornimat, decorative cladding panels for: v Façade cladding (vertically applied, non sloping). v Roof eaves. v Ceilings and awnings. Ornimat SVK Ornimat façade cladding boards are flat decorative fibre cement panels. The front side is provided with a coloured layer (a durable two-component PU coating). The backside is treated with a layer. Because SVK produces the boards true to size, the edges are also squared and coloured. The maximum panel sizes are 3070 x The thickness is 8 mm. Simson PanelTack HM features v Durable elasticity and high mechanical strength. v Optimal tension distribution. v KOMO certificate SKG based on the Guideline BRL 4101 part 7. v Good moisture- and weather resistance. v Simple and quick mounting. Simson bonding system The bonding system consists of: v PanelTack HM v Primer SX Black v Primer PanelTack v Easy Clean Wipes or Cleaner 14 v FoamTape 12 x 3 mm elastic adhesive. primer for wooden support construction. primer for metal support construction. SKG for the pre-treatment of the bonding side of the panel. for the initial bonding of the panels and to guarantee a sufficient mass thickness of the applied adhesive.

2 information for the construction designer Dutch National Technical Guideline BRL 4101 part 7 Simson PanelTack HM has a KOMO-Certificate (SKG ) as Adhesive for the fixing of exterior wall cladding panels. This KOMO-Certificate is based on the Guideline BRL 4101 part 7. Support- Primer Pretreatment Calculation Calculation Maximum construction panel shear value tensile value permissible strength strength displacement N/mm 2 N/mm 2 mm Wood Primer Easy Clean SX Black Wipes or Cleaner Metal Primer Easy Clean PanelTack Wipes or or Cleaner Conforming to the Guideline the following safety factors must be taken into account for constructional calculations: For tensile strength factor 4 and for shear strength factor 10. The width of an adhesive bead is approx. 13 mm. Weight load of panels The load as a result of the weight of the cladding panels is not normative for collapse. The calculation value for shear strength which must be used conforming to the KOMO-Certificate is 0.23 N/mm 2. Wind loads As part of the Dutch Bouwbesluit (constructional decree) wind loads must be taken into account. See for the Netherlands the Standard NEN 6702 and for Belgium NBN-B Because of the required safety factor in the Guideline BRL 4101 a tensile strength of 0.40 N/mm 2 must be used for calculations. Starting from the advised adhesive consumption and at normal applications at a height till 150 metres (wind speed area 1) one may presume that the demands of Standard NEN 6702 will be met. Maximum panel size PanelTack HM is highly elastic therefore possible deformation of the panels can be absorbed in the adhesive layer. When mounting the Ornimat panels a maximal occurring (diagonal) deformation less than 1 mm/m 1 must be taken into account. According to the Certificate based on the Guideline BRL 4101 part 7 the maximal elastic displacement, which still can be absorbed in practice by the standard PanelTack HM system, may not exceed 3 mm. This means that the max. standard panel sizes may be bonded. Remark: Panels must be evenly flat prior to bonding. In this aspect large panels are more critical than small panels, therefore extra care regarding correct handling and storage is inevitable. Support construction: dimensions and distances The minimal widths of supports in the support construction depend on the function of the supports: I. support for joints 95 mm II. end- and intermediate supports 45 mm Also see detailed drawings. Minimal thickness of the (wooden) support 19 mm

3 When bonding the Ornimat panels the following maximal mounting distances between the vertical supports are advised: Building height 0-8 metres Building height 8-20 metres 1 span 2 or more spans peripheral edges 1 span 2 or more spans peripheral edges 50 cm 60 cm extra intermediate 50 cm 60 cm extra intermediate beam beam Remark: If the panel manufacturer requires smaller distances in specific circumstances than the ones which are mentioned in the table, these maximal distances as required by the manufacturer must be used. Support construction: ventilation Behind the panels there has to be an open ventilated cavity of minimal 22 mm. Furthermore ventilation openings/slots at both top and bottom of the bonded panels as required by SVK. Support construction: choice of material Suitable timber: Four-sided clean-planed, clean, dry, dust- and grease free types of wood (spruce, meranti etc.) Wood types need to be sufficiently durable for building constructions Maximal moisture content of the wood is 18%. The wood may contain preservatives based on salts, zinc and copper according to the Dutch NEN 3251 Standard (e.g. Wolman salts). Suitable metal: Dry and smooth (galvanized) steel or (anodized) aluminium. These metals must be rustproof and after fixing they must conform to the Dutch NEN 6702 Standard. Enamelled metals are suitable as well, however different instructions for use may apply. Consult Bostik about this. Lacquers: A limited number of lacquers applied by means of spraying, are suitable for bonding with PanelTack. Consult Bostik about this. Minimal joint width For both practical and esthetical reasons a joint between the panels with a width of 10 mm is recommended.

The following conditions apply: v Do not pre-treat or bond in case of precipitation. v Do not pre-treat or bond in case of high air humidity for instance during dense fog. v Avoid condensation on both the panels and support construction (dew point measurements are advisable). v Apply between +5 C and +30 C.

4 Method of use in steps 1. Pre-treatment support construction The support construction must be primed before or after mounting. The primer can be applied both in- and outdoors. Use Simson Primer SX Black for wood and Simson Primer PanelTack for metal. One (continuous and closed) coat of primer is sufficient. Do not apply more primer than can be bonded within 6 hours. Residues of primer should not be used. Avoid contamination of the support construction with dust and grease after application of primers. Wooden support construction: Shake the unopened tin of Primer SX Black well before use and pour the primer into a clean paint tray. Use the special application set with the rollers for Primer SX Black. Apply the primer to the adhesion surface in a continuous and closed coat or film. After application the minimal drying time is 60 minutes. Metal support construction: Apply Primer PanelTack straight from the tin on a clean, lint free and pigment free cloth or tissue paper. Firmly rub the metal with the primer-soaked cloth. Minimal drying time after application 10 minutes. Replace cloths regularly by new Pre-treatment wooden support construction with Primer SX Black ones. 2. Pre-treatment panel Use Simson Easy Clean Wipes to clean and pre-treat the backside (bonding side) of the panel. Rub the panel firmly with the wipes over the full length and in widths of min cm (there where the adhesive beads ought to be). These ready for use non-woven tissues are more user- and environmental friendly than the usual solvent containing primers and cleaners. The alternative pre-treatment is Simson Cleaner 14. Pre-treatment of the backside/ bonding side with Easy Clean Wipes 3. of Simson FoamTape Once the primers have dried, FoamTape is applied only vertically to the support construction without any interruption. Press FoamTape firmly onto the support construction and cut it with a sharp knife. When deciding on the correct position and length of the tape also bear in mind the dimensions and function of the supports, the dimensions of the panels and the necessary space for the adhesive. Do not immediately remove the protective layer after application of the FoamTape. (See step 5). 4. of adhesive with special nozzle Apply PanelTack HM only vertically and without interruption after the application of the foam tape. Use a hand- or an air pressure caulking gun. A special V-shaped nozzle has been packed with every cartridge PanelTack HM. This enables to apply a triangular adhesive bead with a width and height of 9 mm. Using this special nozzle prevents the enclosure of air bubbles and unnecessary loss of adhesive. Opposite the V-cut one can cut the nozzle obliquely.

5 5. Placing the panel Now remove the protective layer from the foam tape. Apply the cladding panel within 10 minutes after the application of the PanelTack HM adhesive. Fix the panel by gently pressing it onto the adhesive beads and, if necessary, correct its position. Correction is still possible until the panel touches the foam tape. For good and easier positioning of the panel eventually use a joint spacer, supporting blocks or horizontal supporting laths. For easier handling a glass suction clamp also can be useful. Once the panel has been positioned correctly, the panel must be pressed down firmly over the entire length of the FoamTape. Now it is no longer possible to correct the panel position. See the detail drawings. 6. Cleaning Uncured primer or uncured adhesive residues can be removed with a suitable cleaner such as Simson Liquid 1. Use a clean, lint free and pigment free cloth or tissue paper. Test on a small scale if the cleaner does not attack or contaminate the panel. Detail drawings Façade/wall (front view) l.
