Fillers and Pigments
A1 can be filled with various materials, such as pigments, sand and stone, organic fillers and lightweight fillers. This means the look of A1 can be adjusted to the wishes and requirements of the user. A number of fillers affect the weather resistance.
A1 can be painted after it is ready, but can also be coloured beforehand by using pigments. The pigments are added to the resin before mixing.
The maximum quantity of pigment is 2% of the total weight or 6% of the resin weight.
There are various metal powders available which can be added to A1 to achieve a metal effect. When you would like to achieve a rusted effect, use the iron power. Add an equal amount of iron powder as the amount of powder used to produce A1. When the applied layer has dried, it needs to be sanded using a wet scourer or waterproof sanding paper. The surface can now be treated with hydrochloric acid, ammonia or any other agent of your choice. This accelerates the rusting process. When the desired effect is achieved, the process can be stopped by using water and soda. To make sure the effect is maintained, a sealer can be applied. If the sealer is not applied, the process will continue as it would do naturally.
In order to achieve a bronze effect, an equal amount of bronze power needs to be added to the A1 as the amount of powder used to produce the Acrylic. When the applied layer has dried, it can be sanded using a wet scourer or waterproof sanding paper. This brings the bronze particles to the surface. The surface is now ready for the application of special patinas for bronze. A sealer is then used to protect the surface against further ageing or is left untreated to continue the process as it would do naturally.
ATP powder is a volume thickener. It enables the A1 to be thickened to achieve a consistency of putty. This putty can then be used to make the surface smooth and add the finish to the object.
Sand and quartz mixed in with A1 result in a scratch resistant and hard top layer. A granito or granite look can be achieved by using different colours and sizes of quartz. If that is the look you are looking for, you need to sand the top layer after it has set to bring the stone to the surface and achieve a bigger contrast.
Poraver is a very lightweight filler. The round granules are available in the following sizes: 0.5 –1, 1-2, 2-4 and 4-8 mm. This product is used to make lightweight fillings in objects in instances when solid casting would be too heavy.
