Question 1

How does AMS-80 differ from non-reactive silicone slip additives?

Accepted Answer

AMS-80 carries methacrylate reactive groups that covalently bond into the crosslinked network during cure. This eliminates the migration and inter-coat adhesion failures common with non-reactive silicone oils while delivering a durable Crockmeter resistance improvement of approximately 2 grades (ASTM D5264).

Question 2

At what level should AMS-80 be incorporated into a 2K polyurethane topcoat?

Accepted Answer

Add AMS-80 at 0.5–1.5% on total formulation weight to the base component before activator addition. Levels above 2% risk impairing inter-coat adhesion in multi-layer systems. For UV-curable topcoats, incorporate directly into the formulation at the same dosage range.

Question 3

Can AMS-80 be used in waterborne industrial topcoats?

Accepted Answer

AMS-80 is designed for solventborne and high-solid systems. For waterborne formulations, pre-emulsification in a co-solvent such as propylene glycol methyl ether (PM) at a 1:5 ratio before addition to the aqueous phase is recommended. Compatibility testing at intended pH is advised.
