TECHNO CAST™ 8023 – Low-Shrinkage Epoxy Casting Resin for Foundry Patterns and Thick Molds

TECHNO CAST™ 8023 is a slow-setting, two-component epoxy casting resin designed for foundry patterns, industrial molds, and tooling fixtures. Its low viscosity helps reproduce detailed shapes, while its controlled exothermic reaction supports casting thicker sections.

With extremely low shrinkage during curing, high hardness, and impact resistance, TECHNO CAST™ 8023 produces durable, dimensionally stable castings for industrial applications.

Designed for Pattern Making and Industrial Tooling

Foundry Patterns and Shape Replication

Replicate shapes and detailed features from existing parts or master models. TECHNO CAST™ 8023 is suitable for casting foundry patterns and creating molds using tooling boards and patterns.

Thick Molds and Tooling Fixtures

The slow-setting system allows casting and curing in sections up to 13 cm thick, making it suitable for substantial molds, tooling fixtures, and other industrial castings.

Key Features and Benefits

Extremely Low Shrinkage

Minimal shrinkage during curing helps preserve dimensions and accurately reproduce the original shape or pattern.

Low Viscosity

The resin flows into mold details and intricate geometries, supporting accurate shape reproduction.

Controlled Exothermic Reaction

Controlled heat generation during curing makes the system suitable for thicker castings and larger mold sections.

High Hardness and Impact Resistance

With a hardness of 86 Shore D, the cured epoxy provides a hard, durable surface for demanding pattern-making and tooling applications.

Good Self-Adhesion

Good adhesion between properly prepared epoxy layers supports mold construction and subsequent material additions.

100% Solids, VOC-Free Formulation

The system contains no volatile organic compounds and cures to form a solid epoxy casting.

Typical Applications

• Foundry patterns and pattern duplication
• Molds made from master models or tooling board patterns
• Thick-section industrial molds
• Tooling fixtures
• Detailed shape replication
• Industrial casting components
