T-Prime 130-1 EPOXY TOOLING INFUSION SYSTEM ¬ Thermally stable up to 130°C (266°F) when fully postcured ¬ Resistant to thermal cycling damage ¬ Low initial mixed viscosity for easier infusion; 247 cP at 25°C (77°F) ¬ Long pot-life and gel time; capable of infusing large or complex moulds ¬ Ambient curing and low shrinkage for accurate mould manufacture INTRODUCTION T-Prime 130-1 is an epoxy tooling system for manufacturing glass or carbon moulds from liquid infusion processes. T-Prime 130-1 is compatible with Gurit’s range of 130°C tooling gelcoat, laminating and repair systems. T-Prime 130-1 is a low shrinkage ambient curing system, which provides a simple way to produce high accuracy moulds. Designed for infusion and cure at ambient temperatures, it should then be mid-cured at 40°C (104°F) for 4 hours to guarantee the strength needed for demoulding. It can then be postcured off the plug to give a material that is thermally stable to 130°C (266°F). Exceeding this temperature will cause a rapid loss in stiffness and a safety margin is required for the maximum tool operating temperature to prevent distortion or tool damage. T-Prime 130-1 is a further improvement on T-Prime 130 giving improved storage stability and an extended pot-life.

MIX RATIO T-Prime 130-1 should be mixed at the following mix ratio: T-Prime 130-1 Resin T-Prime 130-1 Hardener 100 : 27 (by weight) 100 : 33.3 (by volume) Any deviation from the prescribed mix ratio may degrade the thermal capability and physical properties of the material. The mix ratio of the newer T-Prime 130-1 is different to the older version of the product, T-Prime 130. * Pot life in larger volumes can be reduced. Material approaching its pot life is typically 40-50°C (104 - 122°F) in the centre of the pot and it will then thicken as it cools in the laminate and feed pipes. This...

T-Prime 130-1 Viscosity Isothermal CAP 2000 Time (minutes) T-Prme 130-1 Temperature vs Time at Centre of 500g Pot Life Test Large volumes of T-Prime 130-1 left in bulk > 50mm deep can exotherm strongly and the excess will need to be dispensed into a shallower vessel. Ideally this should be less than 30mm deep or the pot placed into water to cool.

APPLICATION NOTES ■ A good level of understanding of the infusion process is required to achieve a high quality mould. Contact SP-High Modulus for further advice or refer to SP-High Modulus process notes for further information. ■ Any deviation from the prescribed mix ratio may degrade the thermal capability and physical properties of the material ■ Recommended workshop temperature is between 18°C and 25°C (64°F and 77°F) ■ If "drill" style mixing is used, this must be on the lowest setting to reduce the air introduced. Particular attention is needed to mix the sides and bottom of the...

POST CURE To achieve full postcure ramp at 0.2°C /min to 120°C (8.5 hours) and dwell for 2 hours (0.36°F /min to 248°F). Faster postcure risks thermal softening of the tool. Contact SP for advice when in doubt. Net Resin Figures - No waste allowance

Net Resin Figures - No waste allowance A general 10 to 15% waste value is then recommended for purchase estimation. Additional resin is also required for infusion consumables. Resin waste in feed meshes and pipework depends on the component geometry and infusion design. As approx guide resin allow; ■ Small Infusion (Up to 2m2) Approx 2 Kg/m2 (Generally have a higher % waste) ■ Large Infusion (20m2 and above) Approx 1 Kg/m2 For the first components, and when new to infusion, allow extra resin for feed pots.

HEALTH AND SAFETY The T-Prime 130-1 system has been designed for use in closed mould processes. Users should ensure that some elevated temperature cure is applied to the component before trying to machine it. In a component made from T-Prime 130-1, which has seen no heat, there will only be a partial cure. Therefore the sanding dust will be more irritating than dust from a laminate cured at elevated temperature, in which there will be more thorough cross linking. Particular care should also be taken when removing peel plies from part cured material as this can also product a dust like...

TRANSPORT & STORAGE The resin and hardener should be kept in securely closed containers during transport and storage. Any accidental spillage should be soaked up with sand, sawdust, cotton waste or any other absorbent material. The area should then be washed clean (see appropriate Safety Data Sheet). Adequate long term storage conditions will result in a shelf life of 12 months for both the resin and hardener. Storage should be in a warm dry place out of direct sunlight and protected from frost. The temperature should be between 10°C and 25°C. Containers should be firmly closed. Hardeners,...
