DIPON Epoxyplast 3D B100 UltraPour 30 kg - Clear Epoxy Resin for the Production of Tables, Maximum Casting Thickness 10 cm

Always check that the epoxy resin component (component A) has not crystallized before starting work. For more information, please refer to the datasheet under "Crystallization (milky, viscous or cloudy mass in component A)"

Application and Use

1. Check the ambient temperature, it is the most important parameter next to the casting volume. Successful application depends on the room temperature and the amount/volume of resin/hardener mixture used. Too high a room temperature can lead to a very strong exothermic reaction resulting in yellow discoloration, cracking and vapor formation in the mixture.
2. Before application, check in a preliminary test the tolerance of the materials to be coated/cast.
3. Recommended procedure for the most accurate measurement of all components is by weight, weighing accurately at 100:50 or 2:1 parts by weight based on component (A). A deviation, however slight, results in prolonged or no hardening. The addition of too much hardener increases the elasticity of the material and reduces the hardness of SHORE D. Too much component A results in a permanently sticky film that is no longer reversible due to polyaddition. Maximum tolerance range is 0.1%.
Maintain the recommended mixing time of three to four minutes and then transfer to a clean container and mix again for three to four minutes to achieve a maximally homogeneous mixture. Use the mixing container only once. Then allow the mixture to stand for about 15-25 minutes before pouring to allow it to self-aerate. The mixture can be placed in a vacuum chamber for excellent bubble removal.
4. Adhere to the recommended maximum speed for mixing both ingredients,which is 300 rpm. this will prevent or minimize air pockets during mixing. Hand mixing is recommended for smaller quantities up to approx. 1 kg. Due to its long processing time, it degasses excellently. For mixing, we recommend using Allway Tools Helix.
5. To prevent the mixture from leaking due to the long curing time, it is important to ensure that the mould is completely sealed. For this purpose, DIPON polypropylene tape is suitable and can be easily separated from the mould after curing. Optionally, a separation wax can be used.
6. Seal (penetrate) wood, porous and absorbent substrates with a highly reactive epoxy resin such as Epoxyplast 3D B20, HoneyResin or EpoxyPlast 100 P to prevent the epoxy resin from penetrating the material and creating excessive air bubbles. The primer must be cured before casting. For an ideal bond, it is recommended to sand the cured primer coat with coarse P100 sandpaper.
7. The air bubbles will usually crack on their own due to the excellent self-venting properties. Epoxy AB Corrector Spray, a flame torch or heat gun can be used to crack air bubbles on the surface from a distance of approximately 15-20 cm.
8. For trouble-free casting of multiple coats, it is necessary to allow the first coat to cure until no sticky threads remain on the protective glove when touched. The epoxy resin mass can be rubbery or sticky. Exceeding this time will result in visible transitions.
9. It is important to note that coatings/castings that are exposed to prolonged UV exposure may discolor locally. Any discolouration does not affect the material properties.
10. Avoid allowing humidity to be above 60%.
11. Avoid contact with moisture during the chemical curing process.

Cleaning

Use acetone or an all-purpose thinner to clean used application items. Once the epoxy resin has cured, it can only be removed by sanding. It is recommended to clean immediately after use.

Crystallization (milky, viscous or cloudy mass in component A)

• Storage below 20°C may accelerate crystallization.
• Crystallized components are decrystallized by careful heating to approximately 55 to 70 °C for several hours in a hot water bath, depending on the size of the container.
• In principle, it is important to keep the decrystallization time as short as possible.
• The maximum temperature should not exceed 70°C.
• After the epoxy resin (component A) has decrystallized, allow it to cool to a suitable processing temperature (15 - 20°C).

Important instructions

• Curing areas: Room temperature is the most important parameter for successful processing of EpoxyPlast 3D B UltraPour. The recommended room temperature for processing EpoxyPlast 3D B100 UltraPour is 20°C with a maximum casting height of 10 cm. It is not possible to cast arbitrarily large areas at the maximum casting height as there is a direct relationship between the exothermic reaction, the amount of material and the ambient temperature. If the exothermic temperature is too high, the result is a yellow lumpy mass.
• Mixing of the mixture: The maximum speed should not exceed 300 rpm. After a mixing time of about 4 min, transfer the material into a new clean container and mix again for 3-4 minutes.
• After mixing: Allow the mixture to stand for 15 to 30 minutes to increase its ability to self-air.
• When casting larger quantities: It is necessary to control the temperature of the mixture. The temperature of the mixture during the chemical curing reaction should be between 20 - 38°C. The temperature must not exceed 50 °C, then the resin will show undesirable effects such as yellowing. Use a non-contact laser thermometer to measure the mixture. To cool the river, a fan can be used to blow air on the river.
