TASK™ 13

Description

This fast-setting two-component urethane cures quickly to a black semi-rigid plastic.

TASK™ 13 has a working time of 3 minutes and a demold time of 20 minutes.

With a Shore value of 50D, this semi-rigid plastics is used for industrial applications such as fast mold making, model duplication, prototyping, durable miniatures, black props, and special effects.

Fully cured castings are tough, durable, and chemical-resistant.

For best results, do not cast into platinum cure (addition cure) silicone molds.

Instructions

Materials should be stored and used in a warm environment (23°C). These products have a limited shelf life and should be used as soon as possible.

All liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Mixing tools and containers should be clean and made of metal, glass, or plastic.

Mixing should be done in a well-ventilated area. Wear safety glasses, long sleeves, and rubber gloves to minimize contamination risk.

Applying A Release Agent

If unsure about surface compatibility, a trial casting on a similar surface finish should be made to avoid damage. Polyurethane, latex, or metal molds should be dry and require a coat of suitable release agent.

A liberal coat of release agent should be applied onto all surfaces that will contact the plastic. To ensure thorough coverage, lightly brush the release agent with a soft brush over all surfaces.

Follow with a light spay and let the release agent dry for 30 minutes.

Before Measuring & Mixing

Part B (blue label) must be stirred well before use.

Measuring

The proper mixing ratio is 100 Parts A to 120 Parts B by weight.

Use an accurate scale to weigh these components properly. Dispense the required amount of Part A into a mixing container.

Weigh out the appropriate amount of Part B and combine with Part A.

Mixing

Shake or stir Part A & Part B before using. Add Part A to Part B and mix thoroughly.

Stir slowly and deliberately, making sure to scrape the sides and bottom of the mixing container several times.

Be careful not to splash low viscosity material out of the container. The higher the mass concentration, the faster the material gels and cures. Do not delay between mixing and pouring.

IMPORTANT: Shelf life of product is reduced after opening. Remaining product should be used as soon as possible. Immediately replacing the lids on both containers after dispensing product will help prolong the shelf life of the unused product.

Using a dry gas blanket will significantly prolong the shelf life of unused liquid urethane products.

Pouring

Pour mixture in a single spot at the lowest point of the mold. If encapsulating an object, do not pour the mixture directly over the object. Let the mixture seek its level. A uniform flow will help minimize entrapped air.

For Best Results

Best results are obtained using a pressure casting technique. After pouring the mixed compound, the entire casting assembly is placed in a pressure chamber and subjected to 4.2 kg/cm² air pressure for the full cure time of the material.

Curing

Use this product with at least room size ventilation or in proximity to a forced outlet air vent and do not inhale fumes. Fumes will quickly dissipate with adequate ventilation.

Castings with significant mass may be hot to the touch and irritate skin immediately following cure. Let casting cool to room temperature before handling.

Demold time of the finished casting depends on mass and mold configuration. Low mass or thin-walled castings will take longer to cure than castings with higher mass concentration.

If making rotational or hollow castings, backfilling with a rigid foam will provide lightweight reinforcement. Foam backfilling is recommended if castings will be subjected to temperatures above 30°C.

Performance

Cured castings are semirigid, durable, and exhibit negligible shrinkage.

They also resist moisture, moderate heat, solvents, and dilute acids.

Mold release must be removed prior to painting or bonding the cured piece.
