SIGMARINE 48 (SIGMARINE BTD) Alkyd Finish 48 is a conventional general purpose modified gloss alkyd finish, primarily intended for use as a finish coat on boottop, topsides, decks and deck machinery.
Sigmarine 48 (Sigmarine BTD) is a modified gloss alkyd finish from Sigma for general use, described in this data sheet as a topcoat especially for the waterline, topsides, decks and deck machinery. The stated properties are fast drying, toughness, water resistance, good weather resistance with retention of suitable gloss, good adhesion under wet and dry exposure, and use on areas alternately exposed to water and air or on deck together with non-slip material supplied separately.
Basic data at 20 °C are listed, including specific gravity, volume solids, VOC, recommended dry film thickness, theoretical spreading rate, drying time, overcoating intervals, storage life and flash point, along with substrate requirements. Application instructions are given for airless spray, conventional spray and brush/roller using thinner 20-05, followed by safety references and the product data sheet number 7238. This manual is written in Chinese.

It is intended especially as a topcoat for the waterline, topsides, decks and deck machinery, and for areas alternately exposed to water and air.
The recommended dry film thickness is 35 microns per coat.
Thinner 20-05 is the recommended thinner for airless spray, conventional spray and brush/roller application, and is also used for tool cleaning.
