- Acrylics Acrylates & Methacrylates
ebalta SG 150 is a four component acryl casting resin. It consists of 2 liquid components and a hardener powder. Both liquid components are filled with the 1,5 amount in ppw of special aluminum powder. The resin cures within 20-30 minutes to well heat-conducting, heat-resistant molds. The cured molds are very well workable by machines. The structure is extremely dense and the machined areas have an aluminum-like appearance. It is possible to cast any quantity, which can be mixed in one or more containers. Altercating or casting in layers is not possible. Therefore it is very important to determine the casting volume exactly in order to avoid that the mixed quantity is too small. Since the hardener powder is hygroscopic, always seal it air-tight. We recommend to sieve it before each use. Linear shrinkage as per mixture listed in the data sheet. Room temperature and starting temperature of resin components are 21°C as per measurement. For other temperatures or a different content of aluminum powder, shrinkage might also be different.

- Processing Instruction
Release treatment: All models and molds have to be treated with ebalta-primer and ebalta release wax T2. The negative, which is treated with the release wax has to be treated with the release film PVA finally. The release film residues can be washed off easily with water after demoulding. Preparation: The wall thicknesses should not be less than 30mm, as otherwise the necessary curing is not achieved. Result: Weakening of the edges, danger of cracks. A after post-curing of the system is not possible. 1. Komp. 1+2 parts by weight 1: 2, casting together and mixing 2. Stirring in of aluminum powder , 1,5 x quantity of comp. 1 + 2 3. approx. 1-2 hours for evacuation 4. 3% hardener powder, refering to comp. 1+2, to be stirred in carefully by hand 5. After further 10 minutes short stirring by hand and then casting Mixing table: please see separate sheet. In case of an open casting mold the casting should be covered with a board after the casting operation, so that the reaction heat of can not escape faster at the back than within the mold, this prevents distortion. Advice: The processing temperature should never be lower than 20°C. All components should have at least this temperature. In case of lower processing temperature, the potlife would be prolonged extremely and the chemical process would start very slowly. In the meantime the aluminum filler would sink in the mold and result in different densities, which lead to distortion of the casting. During curing of ebalta SG 150 temperatures up to 130°C can occur depending on casting thickness. The final strength will be achieved after 24 hours. The resin-aluminum mixture requires a temperature of 19°C - 22°C before casting. Temperatures over 22°C cause shrinkage, temperatures below 19°C lead to expansion of the cast material.
