When combined, um 2k epoxy primer spray can becomes a compact, pro-grade coating system ready for serious metal protection.

Anatomy of a Two-Component System

Em sua essência, um Two-component system inside a Spray can relies on smart Internal structure engineering. Unlike single-mix aerosols, this setup keeps materials apart until activation.

Separate chambers isolate resin and hardener.
A sealed Activation mechanism breaks the barrier on demand.
O interno Mixing process starts seconds before spraying.

Press the activation button.
Shake to blend.
Apply within pot life.

Sob o capô:
