Resin research Additive F for epoxy Resin Research, once tried you will no longer use Epoxy without Additive F.

ADDITIVE F is a miracle in the production of epoxy surfboards. Incredibly effective for numerous features. During lamination, Additive F helps impregnate the fabric, reducing the amount of resin needed, and reduces the possibility of forming those non-clear areas, the banana peel effect, or stretch marks.

During the Hotcoat, Additive F reduces the possibility of the formation of those voids that allow areas of fabric or the so-called “fish eyes” to emerge, ie those tiny holes on the outer coat. They are caused by contamination such as dust or fingerprints or surface defects.

Additive F increases hardness in Barcol. The increase in Barcol makes the board easy to sand and improves the bond between the different layers and consequently also the flexibility. It also does not interfere when new layers are added like paraffinized styrene does in polyester resin. This means that there is no need for any sanding between layers.

NOT SUITABLE for other EPOXY resins!

This additive reacts with chemicals found in other epoxies (Non cycloalephatic). Use only with Resin Research epoxy.

How to use Additive F:

1% of the entire quantity of Epoxy + hardener in lamination

2% of the entire quantity of Epoxy + Hardener in Hot / Gloss Coating

On order bottle starting from 125 ml. enough for 5 kg of Resin Research Epoxy + Hardener.

  • How to use Additive F:

    In lamination: Max 1% of the entire quantity of Epoxy + Hardener

    In Hot / Gloss Coating: 2% of the entire quantity of Epoxy + Hardener

    Notes on use:

    - If your additive solidifies don't worry !! At cold temperatures the additive tends to crystallize and solidify. Just shake vigorously until you quickly reach the liquid state.

    - Essential in hotcoating, dose not exceeding 2% of the total between resin and hardener. To 400ml of resin and 200ml of hardener, total 600ml plan to add up to 12ml (2% of 600).

    - Once you have decided on the quantities, add Additive F to the resin then mix before adding the hardener.

    - Protect yourself with gloves and mask.

    Available in bottles of 50ml (enough for 4kg hardner resin kit), 125ml, 500ml, 1L.
