DIPON Epoxyplast 3D B20 JEWELCAST - Component B hardener

Application and use: Check the ambient temperature — next to the pour volume it is the most important parameter. Successful application depends on room temperature and the amount/volume of resin and hardener mixture used. Too high a room temperature can lead to a very strong exothermic reaction, resulting in yellowing, cracking and vapour formation in the mixture. Before use, check the compatibility of the materials to be coated/cast in a preliminary test. The recommended method for measuring all components as accurately as possible is by weight, weighing exactly at a ratio of 100:50 or 2:1 parts by weight based on component (A). Even a slight deviation results in extended or failed curing. Adding too much hardener increases the elasticity of the material and reduces SHORE D hardness. Too much component A results in a permanently tacky film, which cannot be reversed due to polyaddition. The maximum deviation within the tolerance range is 0.1 %. Keep to the recommended mixing time of three to four minutes, then pour into a clean container and mix again for three to four minutes to achieve the most homogeneous mixture possible. Use the mixing container only once. Keep to the recommended maximum speed for mixing both components, which is 300 rpm, to prevent or minimise air pockets during mixing. Hand mixing is recommended for smaller quantities up to approx. 1 kg. Thanks to its long working time, it degasses excellently. For mixing we recommend Allway Tools Helix. To prevent the mixture from leaking out during the long curing time, the mould must be completely sealed. DIPON polypropylene tape is suitable for this and can easily be separated from the mould after curing. Release wax can optionally be used. Cleaning: Use acetone or universal thinner to clean the application tools. Once the epoxy resin has cured, it can only be removed by sanding. Cleaning immediately after use is recommended. Important note: Mixing in the shipping containers (bottles/canisters) of A (resin) and B (hardener) will result in incomplete curing and a correspondingly poor result. Always weigh both components accurately. The higher the room temperature and the larger the mixed quantity, the faster the exothermic reaction.
