|---|---|
| VOC Information | Theoretically, under ideal conditions, no volatilisation of active monomers or other components occurs during curing of vinyl ester products. This means that the chemical components applied to the substrate during application are fully retained in the coating after curing. In practical application and curing, however, evaporation of small amounts of monomer (e.g. styrene) may occur. According to the EU Industrial Emissions Directive 2010/75/EU, the theoretical VOC content is 10 g/L. This value is based on the theoretical condition that all active monomers react completely and are incorporated into the matrix. |
The ideal VOC measurement method for such products follows the ISO 3233 test standard. The VOC content measured under the following specific conditions is 20 g/L: wet film thickness 750 µm, 2% by weight peroxide, 1.5% by weight Accelerator 9802, and 0.5% by weight Accelerator 9826.
Typical recommended specification range
| Dry Film Thickness | 600–1000 µm |
| Wet Film Thickness | 650–1080 µm |
| Theoretical Spreading Rate | 1.6–0.9 m²/L |
All vinyl ester and polyester coatings may shrink during curing. This makes the practical spreading rate lower than the theoretical. The shrinkage depends on the actual dry film thickness and application conditions.

Consult JOTUN for further additive suppliers.
Order of additive mixing:
Mix 16 L of base paint until uniform.
Ensure the accelerators (JOTUN Accelerator CO1P and JOTUN Accelerator DMA10) are shaken before addition and mixing according to the mixing table, one bottle at a time. If required, add inhibitor (JOTUN Inhibitor No. 53).
Stir uniformly with a power tool for at least one minute.
Add the last additive, the initiator (JOTUN Peroxide No. 1), only when everything required to start spraying is ready.
| Warning | The accelerator must never come into direct contact with peroxides. |
|---|
All peroxides must be stored in a dark, cool environment (below 25 °C), away from all flammable materials. Do not expose to direct sunlight. Use only original or approved containers.
Empty containers should be rinsed with water and stored separately.
Peroxides ignite if exposed to sparks and hot metal dust from grinding or other mechanical work.
The curing reaction generates heat. Fill containers of surplus mixed paint with water to avoid excessive heat build-up.
| Thinner: | Styrene |
| Maximum thinning: | 5 % |
Normally no thinning is required. For application under extreme conditions, consult the local JOTUN representative. Do not thin beyond the requirements of local environmental regulations.
| Note | Where the Korean VOC regulation (Clean Air Conservation Act) and its corresponding thinning limits differ from the recommended thinning volume, the former prevails. |
