M-Coat D

Air-Drying Acrylic Coating – Overview

Air-drying solvent-thinned (toluene) acrylic. Dense white color for easy visual inspection of coverage.
Forms a hard, thin coating capable of high elongation.
Can be removed with M-LINE Rosin Solvent or toluene.
Apply in thin coats to prevent solvent entrapment. Film thickness: 0.1–0.25 mm per coat.

Good general laboratory moisture barrier. Electrical leakage is negligible even when uncured.
Serves as an excellent base coating for subsequent applications of M-Coat B.
Convenient for anchoring and insulating intrabridge wiring and jumper leads.
Chemical resistance is only fair but can be improved by postcure at +80°C for 30 minutes.

Cure Requirements

• Air dry for 15 minutes, then cure for 24 hours at +24°C.
• Alternatively, cure for 1 hour at +65°C.
• Overcoats can be applied 30 minutes after application.
• Coating binder begins to sublimate at +140°C, but residue is inorganic and non-conductive.
