Product Description
EpoxAcast™ 655 + HT Hardener
EpoxAcast™ 655 (formerly Metalset™ A-30) is a versatile aluminum filled castable epoxy resin that is very hard and strong. It is dimensionally stable, even when mass cast up to 512 in³ / 8,390 cm³. Maximum heat resistance is achieved using HT HIGH TEMP hardener (up to 225°F/108°C).
Encapso™ K
Encapso™ K is a water clear encapsulation rubber that looks just like water and is ideal for a variety of encapsulation and display applications.
How Does Encapso™ K Work? – Two clear liquids (Part A and Part B) are mixed together in equal amounts. The mixture is then poured around artificial flower stems or over an object. Encapso™ K cures to a soft rubber over night depending on casting thickness and conditions. When cured, Encapso™ K looks just like water and will last a long time.
