Antiosmotic HS Epoxy Primer 3:2

This particular product is recommended for protecting the laminate below the waterline, especially for repairing laminate affected by osmosis. Epoxy HS primer is a thick-layer epoxy primer designed to repair hull bottom damage.

The product is non-solvent-based, which means it does not contain solvents that could react with substances present in laminate damaged by osmosis, for example. Osmosis repair is a specific process that requires not only the right primer but also proper preparation and repair conditions. The product cures in 24 hours at around 20ºC.

Our FAQ answers to frequently asked questions

Possible causes

Too low temperature of ambitne,
Incorrect proportion of base and herdener,
Mixing two components from two different manufacturers

How to prevent

Apply the correct proportions of components
Maintain steady temperature (around 20ﹾC) during whole hardening process,
Mix the products thoroughly and bleed the mixture.

How to remove

The uncured mass requires complete removal from the surface.

Yes, you can mix Sea-Line polyurethane paints. The only difference are the pigments of polyurethane paints that determine the color of the paint. But remember to keep the right proportions of base, hardener and thinner.

It is not recommended to apply 2K paints over 1K paints. 1K and 2K inks differ in their composition and properties, including hardness, chemical resistance and durability. 1K paints are one-component and dry by evaporating the solvent, while 2K paints are two-component and need to be cured by adding a hardener. Applying 2K paint over 1K paint can cause unpredictable chemical reactions and lead to undesirable effects such as dulling, chipping or flaking of the paint. Therefore, always use paints according to the manufacturer’s instructions and do not mix different types of paints. farby zgodnie z instrukcjami producenta i nie mieszać różnych rodzajów farb.
