All the relevant product data sheets are to be read for additional information like pot life, mixing instructions, surface preparation, ventilation, temperature application limitations, etc.
Surface Preparation
Steel
Surfaces must be free of all rust and millscale. They should be abrasive blasted to a minimum standard of Sa 2,5 of Swedish Code of Practice SIS 055900. If immersion service is contemplated then a standard of Sa 3 should be attained. Anchor pattern must never exceed 100 µm and preferably should be in the 50 – 75 µm range between peak and valley.
Galvanised Steel
Galvanised steel must be completely free of any trace of greasy matter and should be scrubbed with abrasive pad or proprietary abrasive cleaner until completely ‘non-greasy’. The cleaned surface must be well washed with clean water and allowed to dry.
Priming
It is recommended that abe.®cote 352 be applied directly to the prepared substrate. It must NEVER be applied over conventional primers.
Mixing
Stir the contents of each container very well. Add the activator to the base and stir together for at least five minutes using a flat paddle. Stir longer if the mix exceeds 5 litres volume. It has been found that mechanical mixing gives better dispersion than manual mixing. A suitable mixing method would be a slow speed electric drill (approximately 200 r/min) fitted with a paddle.
If only part of a kit is to be used, add one volume of activator to two volumes of base. Measuring must be accurate and separate stirrers and containers used for proportioning each component.
Thinning shall only be done with abe.® thinners No. 3. Up to 10% may be added.
The mixed material must be left to stand for 20 minutes in a cool place prior to application.
Mixing
abe.®cote 353
Add aluminium paste to base component. Stir well and then add activator. Stir together for at least five minutes using a flat paddle. Stir longer if the mix exceeds 5 litres volume. It has been found that mechanical mixing gives better dispersion than manual mixing. A suitable mixing method would be a slow speed electric drill (approximately 200 r/min) fitted with a suitable paddle. The mixed material must be left to stand for 20 minutes in a cool place prior to application.
Application
abe.®cote 352 should always be applied as a minimum 2-coat system and for most uses a 3-coat system is necessary. The first coat of a system may be thinned up to 10 % with abe.® thinners No. 3. Application should preferably be by brush. abe.®cote 352 may be airless sprayed, normally through a 400 – 500 µm tip and up to 10% thinning is permissible. abe.®cote 352 should not be applied if the ambient temperature is below 10°C. The curing reaction will not proceed at low temperature. If the surfaces are not at least 2°C above the dew point there is every chance that a film of condensed moisture may be present. This will adversely effect adhesion of the coating. Wet film thickness should not exceed the recommended figures as solvent entrapment could result. The same condition may be caused if overcoating times are shortened. Solvent entrapment in the film can lead to many problems. When work is carried out in full sun, and surface temperature may rise far above ambient, it will be found that the film will remain thermoplastic until full cross-linking of the coating has taken place.
Application
abe.®cote 353 may be applied by brush or roller, if airless sprayed, normally through a 325 µm tip, airless spray provides a better finish. abe.®cote 353 should not be applied if the ambient temperature is below 10ºC. The curing reaction will not proceed at low temperature. If surfaces are not at least 2ºC above dew point, there is every chance that a film of condensed moisture may be present. This will upset adhesion of the coating. Too early overcoating or exceeding recommended wet film thicknesses can result in solvent entrapment which can lead to disastrous performance. When work is carried out in full sun, and surface temperatures may rise far above ambient, it will be found that the film will remain thermoplastic until full cross-linking of the coating has taken place. While cross-linking of the coating is normally complete in seven days, it is advisable to leave the coating as long as possible up to 28 days before putting it into full service.
Coverage
Depending upon surface profile 3 – 4 m2/litre Smooth surface – 5 m2/litre
Coverage
abe.®cote 353
± 8 m2/L on smooth surface – 2 coats are recommended.
Finish
Colour is a black gloss, should a silver matt finish be required apply abe.®cote 353 as a top coat over the abe.®cote 352.
abe.®cote 353 was developed to provide a decorative finish to abe.®cote 352 painted surfaces. Apply abe.®cote 353 to abe.®cote 352 within 24 hours in order to achieve optimum intercoat adhesion.
Mixing
abe.®cote 353
Add aluminium paste to base component. Stir well and then add activator. Stir together for at least five minutes using a flat paddle. Stir longer if the mix exceeds 5 litres volume. It has been found that mechanical mixing gives better dispersion than manual mixing. A suitable mixing method would be a slow speed electric drill (approximately 200 r/min) fitted with a suitable paddle. The mixed material must be left to stand for 20 minutes in a cool place prior to application.
