Product Applications

Due to these excellent properties AFCONA – 3251 is very suitable for use in:

1. All wood coating systems like NC, acid curing, PU and UV.
2. Topcoats in plastic coating applications such as mobile phones and other plastic items that are frequently touched by our hands.
3. UV coatings, where it offers very good slip and leveling without influencing the clarity of the paint film.
4. Refinish topcoats based on polyurethane.
5. Air dry alkyds; the dosage in this system is very low, 0.02 – 0.05% on total formulation.
6. Others paint systems where high slip is desired.

 Note: AFCONA – 3251 will become slightly hazy at temperatures below 5° C. This will not influence the performance of the product.

Incorporation

AFCONA-3251 may be added at any stage during the production process.

Addition and Dosage

AFCONA-3251 may be added at 0.02 - 0.50% based on total formulation. Under normal conditions, 0.10 - 0.30% based on total formulation is sufficient.
