| EpoxAcast® 690 is a UV resistant clear casting epoxy that is ideal for making clear jewelry/beads or replacement lenses for kit cars and other applications requiring a rigid, clear finished product. EpoxAcast® 690 can be colored with SO-Strong® color tints. EpoxAcast® 690 is also suitable for making clear molds and prototype parts. Castings cure with negligible shrinkage and are very hard and strong. EpoxAcast® 690 is also suitable for electronic assembly encapsulation applications where component identification is necessary. Recommended casting thickness maximum; 2 in. / 5 cm.&& |
