Water-exposure plan

Splash, filling and continuous immersion are not equivalent

Brief moisture

Splashes or dampness can use a different milestone.

Continuous water

Filling, launching or immersion requires the exact water milestone.

Use the Alkyd finish (US sheet) directions for alkyd enamel and marine paint; do not infer immersion readiness from touch-dry time.

About this product

The US-units data sheet for Interlac 665, an alkyd finish. At 77°F it matches the 661 sheet at 25°C, but the temperature steps are 41, 50, 77 and 95°F.

Using this specific product

International (AkzoNobel) Interlac 665 is listed here as the Alkyd finish (US sheet) version for alkyd enamel and marine paint. For repairing marine or RV equipment, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Alkyd finish (US sheet); related versions can use different timing.
  • For alkyd enamel and marine paint, pay particular attention to substrate preparation, temperature and water exposure.
  • At 77°F (25°C).

How to check readiness

Check the immersion or launch milestone—not just touch-dry time. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. Lift or move the item gently and avoid twisting the bond or pressing finished faces together. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required.

Avoid this mistake

Launching too soon can expose an incompletely cured film continuously.
