3215 ET315-1 epoxy tiecoat

Product introduction

3215 is a kind of two-component modified polyamide adduct-cured epoxy coating. itprovides a longer repainting interval for subsequent coatings and excellent interlayeradhesion.

Recommended applications

It is generally used as a transition coating between epoxy coating and physical dryingcoating for good interlayer adhesion in atmosphere and immersion environment. it canbe used as an anticorrosive primer for underwater coatings, a tiecoat for antifoulingcoatings,and a sealcoat for old antifouling coatings.

Construction conditions

Transition coating: Sand blast or use power tools to remove allrust and other loose materials, and remove all residues.Touch-up to complete film thickness.

Sealcoat for old antifouling coatings: Thoroughly clean or spraywith high-pressure fresh water to remove the hydrolyzed layeron the surface of the old antifouling coatings. Make sure the oldcoatings with weak adhesion between layers are completely removed.

The substrate must have a temperature >3°C above the dewpoint. The environment should be <85%RH.

It is recommended to apply at above -5°c. The painting surfacemust be clean and dry.

It is recommended to maintain strong ventilation duringpainting, drying and curing.
