Solvay LTF 318B
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	LTM318-1B is a matrix system developed for the production of 180°C (356°F) capable tooling using oven vacuum bag processing. LTM318-1B offers a 65°C (149°F) initial cure capability, long out life and, after post-cure, resistance to thermal cycling to 180°C (356°F). LTM318-1B used in conjunction with LTF318B ZPREG selective impregnation technology surface films offers new possibilities for the manufacture of cost effective, high quality composite mold tools. Features & Benefits: 30 days out life at 21°C (70°F) 12 months storage at -18°C (0°F) 65°C (149°F) initial cure High quality finish after vacuum only cure when used in combination with LTF318B surface film Maximum long-term continuous service temperature of 180°C (356°F) after full post cure Low tool shrinkage Low tool coefficient of thermal expansion Information provided by Cytec, subsequently acquired by Solvay.
