COLORSIVIT EPOX T A+B
Transparent casting epoxy formulation
Low yellowing epoxy compund to give a "depth effect" to decorative surfaces.
Suitable for castings with a thickness between 3 and 10 mm.
Type: Epoxy Compound
Description
Solvent-free Epoxy product with very low yellowing, and high gloss. Applied in castings with thicknesses from 3 to 10 mm, COLORSIVIT EPOX T hardens without shrinkage maintaining a smooth, perfectly deaerated surface that allows to see the substrate. In this way drawings and objects can be incorporated.
Use
"Depth effect" for decorative surfaces. Incorporation of artistic elements.
Support
The surface receiving the casting must be solid, dry, not polluted by oils, detergents, powders or other release substances. The temperature of the substrate must be >15°C.
Preparation of the support
On resinous flooring the perfect adherence of the coating must be verified; If so, abrasive and proceed to application. In case of casting on wood or porous surfaces, seal at best by applying a coat of COLORSIVIT EPOX CLEAR TIX.
Application
At the time of application, combine the components in a single container and mix slowly and homogeneously for at least two minutes. Carefully respect the ratio of mixture by weight.
Pour the product on the surface to be coated with a minimum consumption of 3 kg/m2 to obtain a thickness of 3 mm. Castings less than 3 mm thick are not recommended as the surface could show aesthetic defects.
Flows greater than 10 mm thick that could manifest tensions and exothermics are not recommended.
Immediately after casting it is possible to distribute the product on the surface by notched trowel. If necessary, pass the spiked roller to even out the surface and facilitate the deaeration of the system.
COLORSIVIT EPOX T can be colored by adding to the mixture suitable inks, compatible colored pastes, powder pigments or metal pigments (provided they are perfectly dry); translucent or fully covering effects can be achieved.
Reports of use dyes:
- for "translucent" effects, use up to 1.0% by weight of solvent-compatible inks
- for "opaque" effects use up to 1.0% by weight of concentrated coloring pastes for epoxy (COLORPASTA EPOX)
- powder, metallic or other pigments must be evaluated on a case-by-case basis with preliminary tests to test compatibility and intensity of effect.
If you want to increase the chemical resistance of the surface, apply a top-coating after sanding with 220-360 grain; after sanding remove dust completely.
Warnings
The coatings of COLORSIVIT EPOX T exposed to sunlight may undergo fading or color variations with a turn towards yellow: this fact does not affect in any way the performance of the coating.
Between different production batches of the same color there may be slight differences: when it is possible to use material from the same batch. For low temperature applications, the material can be heated to 25°C for easy application and catalysis (viscosity decrease).
Product for professional use, the buyer undertakes to follow the above warnings in the application of the purchased product and the instructions in the safety data sheet.

| Solvent for cleaning tools | UNI Solvent |
| Storage | 12 months, store in a dry place at a temperature between 15°C and 35°C Before using the product, check that component ''A'' is transparent. The presence of white crystals would indicate a partial crystallization of the product. To eliminate these crystals (reversible phenomenon) heat the component ''A'' in a bain-marie until a transparent liquid is obtained. |

| Hardening in depth (50% R.H.) | at 25°C 7 days |
| Ambiental conditions of application | Temperatures between +15°C and +30°C, R.H. < 50% and media humidity < 4% COLORSIVIT EPOX T applied at substrate temperatures below 15°C could stain in contact with water, or with water-based preparations, and form whitish spots. Such a defect in chemical resistance is caused by incomplete cross-linking. Therefore, COLORSIVIT EPOX T should be applied at a substrate temperature not lower than 15°C and at least 3°C higher than the condensation temperature. |
| Coating maintenance | For cleaning operations use neutral detergents |
