> RELEASE AGENT FOR COMPOSITE PARTS
EUROCOAT is a versatile non-VOC release agent specifically developed for the composites industry.
This semi-permanent release agent acts as a barrier between the mould and the composite part. The solid content is very high and the solvent content is only 3%. EUROCOAT is stable up to temperatures of 400°C (752°F).
EUROCOAT is available in liquid form or as impregnated wipes SATWIPES C86 that meet AMS 3819 B and BMS 15-5 certifications. The SATWIPES C86 are ideal to control the product application and consumption
- 97% dry content
- Very low Volatile Organic Compound (VOC) release
- Improves users' safety
- ONLY one layer of product application is necessary
- Time saving in application because no waiting time for evaporation
- Non-migratory release system
- No contaminating transfer onto the composite part
- Easier removal of parts from mould
- Lower mould maintenance costs
- Does not foul up the mould
- No mould build-up
- Easier mould regeneration
- Lower mould maintenance costs compared to other release agents
- Re-application of Eurocoat is less frequent compared to any other release agent
- Time saving in production
- Product available in liquid form or impregnated on Satwipes C86 15x23cm
- Standardised product preparation operation
- Reduces the quantity of product used
Eurocoat - releasing agent - brings
- high solids, a third technological way versus the current existing solutions with hardly no VOC emissions
- an excellent quality of release
- a Eurocopter's approval
EUROCOAT can be used with thermosetting resins (epoxy) cured up to 400°C (752°F). It can also be used with phenolic resins, pre-pregs, resins curing at high temperature or other resins.

1/ GREEN MOULD (OR FIRST USE OF THE MOULD)
A. Sanding with Scotch Brite pad or abrasive paper
B. Degreasing with a solvent such as DIESTONE DLS, DIESTONE A8284, DIESTONE A8290. All traces of previous release must be removed.
C. EUROCOAT can be applied to mould surfaces from room temperature up to 60°C/140°F by spraying, by wiping with a cloth or with SATWIPES C86 15X23 (cm). Apply a thin and homogeneous layer of release agent on the mould at the ratio of 1 wipe per m². To be sure to have a good application of the release agent, the mould surface has to be bright.
Don't over apply EUROCOAT as it will not improve performance.
D. Use a dry wipe to remove the possible release agent excess.
E. Allow the release agent layer to cure at 130°C (266°F) for at least 1 hour. Curing can also be done by UV/C with mercury H lamp (minimum advised power 120 W/cm, for a rate of 6m/min)
After curing, EUROCOAT looks like a varnish.
2/ REGENERATION OF THE RELEASE AGENT LAYER
Re-coating once, after a few pulls can enhance performance. Directly apply the release agent on the mould surface without previous sanding or degreasing.
The layer of EUROCOAT is glossy on the mould. After each utilisation the aspect of the mould becomes more matt. When the surface is completely matt, reapply EUROCOAT on the entire mould.
3/ MOULD TOUCH UP
Touch up coats should only be applied to areas where poor release is noticed. In this case a new cure cycle is necessary (cf. § 1/E).
This will reduce the possibility of release agent or polymer build-up. The frequency of touch ups will depend on the polymer type, mould configuration, and abrasion parameters.
