| General |
|||||||||||||||||||||||||||||||||||||||||||||
| UV Resistant clear laminating resins, free
from synthetic phenol. Resistant to oil. Absolutely waterproof to fresh
and salt water. Moisture will not cause white discolouration.
The resins will adhere very well to glass, carbon and kevlar fibres as well as to wood. GRAF RESIN HT 136 is particularly recommended for producing laminates with carbon fibres including woven rovings. It has a very high heat distortion temperature (over 100°C). The resin is highly scratch and impact resistant, so makes an ideal top coat. After a few days curing at room temperature damage will not cause white cracks to appear. |
|||||||||||||||||||||||||||||||||||||||||||||
| Preparation |
|||||||||||||||||||||||||||||||||||||||||||||
| After weighing out the correct quantities according to the mixing ratio, stir very well otherwise there is a risk that sticky spots will remain on the finished laminate or top coat. It is recommended that the mixing vessel is swapped after stirring for about three minutes, this will benefit complete mixing. The potlife is approximately 20-30 minutes at 20°C. | |||||||||||||||||||||||||||||||||||||||||||||
| Applications |
|||||||||||||||||||||||||||||||||||||||||||||
| The outstanding properties of this new
epoxy system makes it particularly suited for laminating surfboards,
boats, ships, crash helmets, sledges, skis, gliders, model aeroplanes,
etc. The low viscosity of the resin means that several layers of fibre can be glued at once. The resin cures quickly and is sandable after 4 hours (this of course depends on temperature). When set the surface can be polished and the surface has a high gloss and smooth i.e. brush marks etc. will vanish. |

| Repairs |
|||||||||||||||||||||||||||||||||||||||||||||
| Osmosis repairs can be undertaken with this resin, usually in combination with GRAFFILL PUTTY, GRAF EPOXY GELCOATS and GRAF EPOXY TOP COATS. | |||||||||||||||||||||||||||||||||||||||||||||
| Coating Wood. |
|||||||||||||||||||||||||||||||||||||||||||||
| GRAF SURF EPOXY HT 126 A/B is particularly
suitable for the impregnation and varnishing of wood because of it's
transparent, highly glossy , Ultra Violet and scratch resistant surface.
Old weathered wood and veneers need to be sanded well for the resin to get a good key, and be free from all traces of the old coating. Squeeze GRAF SURF EPOXY HT 126 A/B as thin as possible into the surface using a squeegee (see footnote 1), ensure that all the resin is squeezed into the wood and that no surface resin is left on the surface. If necessary this process can be repeated particularly if large holes remain in the surface. Finally, if a glossy surface is required the last layer should be applied thicker, the resins self levelling properties will result in a good surface finish. Generally this working method will work just as well with new wood and veneers. |

| Coating Foamblanks. |
|||||||||||||||||||||||||||||||||||||||||||||
| The resin can be used directly on the foamblank or under a top coat. However before continuing with the lamination, time should be allowed for any solvents to evaporate. The recommended top coat for adding colour would be GRAF TOP 20 A/B WHITE or BLACK of COLOR. An alternative might be GRAF EPOXY GELCOAT G 20 A/B WHITE or BLACK or COLOR. However, addition of a small quantity of FLUORESCENT COLOR ADD POWDER (FCA-POWDER) to GRAF SURF EPOXY HT 126 A/B will generate a coloured tinge to the resin film, more FCA-POWDER will generate more intense deeper colours. The resin can be applied with spray gun, brush of spatula. | |||||||||||||||||||||||||||||||||||||||||||||
| Top Coats |
|||||||||||||||||||||||||||||||||||||||||||||
A thin layer of GRAF SURF EPOXY HT 126 A/B
applied with a squeegee can make a good final coat over a coloured
surface. However a finer finish will result if GRAF EPOXY TOP 20
TRANSPARENT A/B is used (see data sheets on GRAF EPOXY TOP COATS).

| Physiology |
|||||||||||||||||||||||||||||||||||||||||||||
| Due to its low vapour pressure, this epoxy resin is safe to handle if the usual precautions are observed. GRAF RESIN HT 126 A / HT 136 A is irritating to the skin, eyes and mucous membranes. The hardeners GRAF HARDENER HT 126 B and HT 136 B contain aliphatic amines and hence are corrosive to skin, eyes and mucous membranes. Hence, it is recommended that safety goggles and gloves should be worn. Ensure good ventilation in the work place. In case of skin contact wash well with soap and water. Protective skin creams are recommended. In case of eye contact wash well with water for at least 15 minutes and seek medical advice. Our products are free from other toxic substances such as phenol, phenolic diluents and aromatic amines. The relevant professional instructions for the use of epoxy resins must be followed. | |||||||||||||||||||||||||||||||||||||||||||||
| Storage |
|||||||||||||||||||||||||||||||||||||||||||||
| Store under dry conditions away from water and carbonic acid. The temperature must not be allowed to fall below 15. If these conditions are observed then the product will remain good for at least one year in closed cans. | |||||||||||||||||||||||||||||||||||||||||||||
