VISTA - transparent, UV stable molding resin

is  water  clear polymer  compound made specifically for applications that require clarity.

Low viscosity ensures easy mixing and pouring. VISTA cures at room temperature with negligible shrinkage. Cured castings are UV Resistant and are not brittle. Vibrant colors and color effects are achieved by adding pigments and dyes.

Ventilation .. . good ventilation is essential. You must wear an approved respirator to minimize inhalation of residual fumes. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Make sure mixing tools &containers are dry. Product has a limited shelf life. Use as soon as possible.

Selecting amold rubber . . . VISTA should be cast into Samson Silicones (e.g.Modrin)or polyurethane elastomeres (e.g. Elastopur). Do not use other silicone or urethane rubber products. If you are unsure about surface compatibility, a trial casting should be made. To prevent cure inhibition, post-cure Samson silicones for 8 hours at 60° C and let cool prior to casting resin.

Polyurethane rubber molds should be dry and require a coat of a suitable

release agent (Universal Mold Release V-1 available from Samson Kamnik) before casting.

For best results . . . Pre-heat the rubber mold
100°C for 4 hours before mixing & pouring Vista

This will minimize the chances that cured castings will exhibit casting phenomenon such as fish-eyeing, suck back,corner rounding, large bubbles, etc.

Measuring . . . VISTA  should be stored and used in a warm environment (22° C). These products have a limited shelf life and should beused as soon as possible. The proper mixing ratio is 115 A:100 B by weight. You must use an accurate scale (gram 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.

Important: Shelf life of product is drastically reduced after opening. Immediately replace container lids after dispensing. Use remaining product as soon as possible.

Mix thoroughly for 2 -3 minutes making sure that you scrape thesides and bottom of your container several times. If coloring or filling VISTA,add filler or pigment dispersion to Part A and mix thoroughly before adding Part B. After mixing,empty contents into a new, clean mixing container and mixa gain thoroughly.

To Minimize Air Bubbles - Vacuum de-gas prior to pouring..Subject mixture to 29 h.i.g. mercury in a suitable vacuum chamber for 2 -3minutes or until mixture rises, breaks and falls. Allow for 3 to 4 times volume expansion in container.

Pouring- pour mixture in a single spot at the lowestpoint of the mold and let the mixture seek its level.

For Best Results . . . Best results are obtained using a pressure casting technique. After pouring the mixed compound, the entire casting assembly (mold,dam structure, etc.) is placed in a pressure chamber and subjected to 4.2 kg/cm2air pressure for at

least one hour.

Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

Post Curing .. . Castings will achieve maximum physical properties and better heat resistance if VISTA is post cured.

Post curing is recommended if castings are thin or of low mass concentration. Castings should be post cured in a mold or support structure.

Post Cure Schedule: Allow the material to cure for 6-8 hours at room temperature followed by 6 hours at 65 - 72 C. Allow casting or part to cool to room temperature before demolding.

Materials should be stored and used in a warm environment (22° C). Castings will reach ultimate physical properties at room temperature in 5 - 7 days. Castings removed from mold before recommended cure may exhibit a tacky surface that can be eliminated by exposing casting to 65 C for 6 hours.

CastingThickness & Cure Time - The cure time and ultimate shrinkage of VISTA will vary depending on mass concentration, thickness of the casting, mold configuration,etc. For example, a 200 gram mass of VISTA will cure faster if left to cure ina conical vessel (cup) versus a casting dispersed as a thin sheet measuring 3centimeters square by 1 mm thick. This is due to the heat generated by the concentration of material in the cup versus heat that is dissipated from the sheet casting. Castings will resist yellowing when exposed to UV, but may darken over time.

SOME EXPERIMENTATION MAY BE NECESSARY – these products are used for hundreds of applications and we cannot warrant product suitability for any one application. Shrinkage will vary depending on mass and mold configuration.

If there is a question as to whether or not VISTA meets your needs, atest casting is recommended. You can also call our technical help line forassistance.

The Material Safety Data Sheet (MSDS) for this or other SAMSON KAMNIK product should be read prior to use and is available upon request from Samson Kamnik.

Our products are safe to use if directions are read and followed carefully.

Be careful. VISTA Part B is a modified aliphaticdiisocyanate. Vapors, which can be significant if heated or sprayed, cause lunge damage and sensitization. Use only with adequate ventilation. Contact with skin and eyes may cause severe irritation. Flush eyes with water for 15 minutes andseek immediate medical attention.

Remove from skin with waterless hand cleaner followed by soap and water.Refer to MSDS. Use only with adequate ventilation
