EBECRYL® 4683

• Formulations based on Ebecryl®4683 exhibit high reactivity and result in hard films.
• Coatings formulated with Ebecryl®4683 are characterized by very good chemical and mechanical resistance including scratch resistance. Other characteristics are high abrasion resistance and very good resistance to yellowing.

Ebecryl®4683 is used in the formulation of radiation-cured (UV and electron beam) coatings for application by roller coating, spraying or curtain coating on metal substrates.

• As with any product, use of Ebecryl®4683 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
• The UV-curing of coatings formulated with Ebecryl®4683 requires the addition of conventional photoinitiators, up to 5% or in concentrations that satisfy the reactivity requirements of the application.
• In the case of electron beam curing, good inertization must be ensured (risk of surface inhibition). Matt coatings can be produced using conventional matting agents.
• Care should be taken with respect to sedimentation, which may cause the coating to gel prematurely, thus affecting the storage stability.

• Depending on the application, the coatings can be adjusted to application viscosity using standard reactive thinners (mono-, di-, tri- or tetra-acrylic acid esters) or solvents such as butyl acetate.
• Because of the many potential combinations with thinners and solvents, compatibility must be tested in each individual case.

• Storage in original sealed Allnex containers.
• Recommended storage temperature -10 to + 35°C Protect from intense radiation (light, UV), heat and foreign material.
• Allnex guarantees that for a period of 12 months following the day of manufacturing, the product will meet the specifications or values set forth in section “specifications or characteristic data” above, whatever is applicable, provided that the product is stored in full compliance with the storage conditions set forth in and referenced under section “storage” above and is otherwise handled appropriately.
• The lapse of the 12 months period does not necessarily mean that the product no longer meets specifications or the set values. However, prior to using said product, it is recommended to test such a product if it still meets the specifications or the set values.
