Crystic Matched Tooling Systems brochure

Product catalog summary

Overview: This document provides technical specifications and application procedures for various Crystic products used in high-performance tooling systems. These products include gelcoats, skin coats, and resins designed for enhanced durability, chemical resistance, and ease of use in mold construction.

1. Product Specifications:

Crystic Gelcoat 14PA: A urethane-modified vinyl ester gelcoat known for excellent gloss retention and resilience. It offers good chemical resistance and addresses water marking issues.
Crystic VE 679PA Skin Coat: A vinyl ester/DCPD skin coat that reduces fiber print-through, enhancing the surface finish of molds.
Crystic RTR 4000PA: A rapid tooling resin with low profile and thixotropic properties, designed for quick tool making with improved shrinkage control.
Crystic 474PA: A heat and chemical-resistant laminating resin suitable for producing dimensionally stable molds.

2. Application Procedures:

Begin with plug preparation and apply release agents.
Apply Crystic Gelcoat 14PA for a high-gloss finish.
Use Crystic VE 679PA Skin Coat to enhance surface quality.
Construct the mold using either Crystic RTR 4000PA for rapid tooling or Crystic 474PA for conventional construction.
Finish the surface with Crystic Primecoat and Glosscoat for optimal results.

3. Typical Properties:

Crystic VE 679PA: Red/Brown appearance, viscosity of 3.5 Poise at 37.35 sec-1, specific gravity of 1.065, and a gel time of 18-23 minutes depending on the catalyst used.
Crystic 474PA: Cloudy/Mauvish appearance, viscosity of 5.3 Poise at 37.35 sec-1, specific gravity of 1.10, and a gel time of 12 minutes with 2% Catalyst M.
Crystic RTR 4000PA: Light Brown appearance, viscosity of 5 Poise, specific gravity of 1.35, and a gel time of 35-40 minutes with 1% Catalyst M50.

4. Mechanical Properties:

Crystic 474PA: Barcol hardness of 48, deflection temperature under load of 112°C, tensile strength of 57 MPa, and elongation at break of 1.8%.
Crystic RTR 4000PA: HDT of 63°C, tensile strength of 114 MPa, and elongation at break of 2.0%.

5. Recommendations:

Crystic 14PA is highly recommended for its superior performance in tooling applications, offering reduced water marking and enhanced gloss retention.
For rapid mold production, Crystic RTR 4000PA is suggested due to its fast curing and handling properties.
