Accu-Cast™ BucketGel™ 390 /2,2 kg

Accu-Cast™ BucketGel™ 390 Alginat ist ein schnell aushärtendes, festes Alginat-Formmaterial, das sich ideal zum Einpressen von Objekten eignet, um einen detaillierten Negativabdruck zu erstellen.

BucketGel™ 390 hat eine Aushärtezeit von ca. 3 Minuten, wenn es mit Wasser mit einer Temperatur von 32°C gemischt wird. Sie können LiquiStone™-Gips in die Form gießen, um eine Reproduktion herzustellen.

Mischungsverhältnis nach Gewicht: 1 Teil Pulver zu 4 Teilen Wasser nach Gewicht
Mischungsverhältnis nach Volumen: 2 Teile Pulver zu 3 Teilen Wasser nach Volumen

Spezifisches Volumen: 26 cu. in./lb Topfzeit: 2 Minuten* Aushärtezeit: 3 Minuten* Farbe: Gelb

*Abhängig von der Wasserqualität (siehe Abschnitt "Wasserqualität" unten) und einer Wassertemperatur von 32°C

Instructions

PROCESSING RECOMMENDATIONS

Keep Out of Reach Of Children.

Safety - Wear safety glasses to minimize contamination risk. Use only in a well-ventilated area. Wear a NIOSH-approved N95 dust mask when processing powdered material.

WARNING: IRRITANT TO EYES & MUCOUS MEMBRANES. Do not get in eyes, or in mucous membranes. Do not take internally. Do not breathe particulates. Use only with adequate ventilation.

PROCESSING RECOMMENDATIONS

Preparation - These products have a limited shelf life and should be used as soon as possible. Materials should be stored and used in a warm environment 23°C. Mixing containers should have straight sides and a
flat bottom. Mixing sticks should be flat and stiff with defined edges for scraping the sides and bottom of your mixing container. BucketGel™ 390 powder may get warm in storage/shipping during the summer months
which may cause the powder/water mixture to set too fast. To remedy, store BucketGel™ 390 alginate in a cool area (16°C - 21°C) for 24 hours before using. Do not allow moisture to come into contact with
unused BucketGel™ 390 alginate powder.

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

MEASURING,WATER QUALITY AND WATER TEMPERATURE

Measuring - BucketGel™ 390 is mixed 1 part powder to 4 parts water by weight or 2 parts powder to 3 parts water by volume. If measuring by volume, fill measuring cup with powder, and level off the top. If measuring by weight, use an accurate gram scale. You can vary the water level somewhat to change the consistency of the mixture. Less water will make the alginate thicker. More water will make the mixture thinner and easier to pour.

Be Careful... too much water may result in the mixture not curing! Since powder is a compressible material, by weight mix ratio is recommended.

Water Quality - If water quality is in question, use distilled water heated to the correct temperature using a stove top or microwave oven if needed. Check water temperature using a thermometer. Water that has a high mineral content (calcium, phosphate, etc.) may cause any alginate to become “lumpy” or not set properly. If you have a water softener, the water will delay the pot life and cure time of the alginate. You can compensate for this by increasing the temperature of the water. A small-scale test is recommended prior to mixing large amounts.

Water Temperature - At 32° C, BucketGel™ 390 will have a working time of approximately 2 minutes and a demold time of about 3 minutes. Warmer water will cause the material to cure faster (less working time). Colder water will give a longer working time and slower demold time.

MIXING ALGINATE

Mixing - Alginate can be mixed by hand in a mixing container using a flat mixing stick with defined edges for scraping the sides and bottom of your mixing container as you mix Alginate materialcan also be mixed in the bag it comes in. Remove all jewelry and watches from hands before attempting to mix the material in the bag to prevent puncture to the bag. Alternatively, you can mix the material using a turbine mixer (mechanical
mixer) and portable drill

PRESSING A MODEL INTO THE ALGINATE

Once mixed, BucketGel™ 390 can be poured into a container for making a mold. Gently press an object or model into the mold to make an impression in the mold.

For Best Results: Do not fully submerge the model into the alginate. Keep your model still until the BucketGel™ 390 sets up. You will know the alginate has set when it is firm and no longer gel-like

CURING AND PERFORMANCE

Curing - Cure time is approximately 3 minutes when mixed withwater at 32°C. Thinner molds made with more water in the mix may set up longer. Performance - Cured alginate molds exhibit moderate tear strength and are firm but flexible. Alginate molds are easy to cut into with a dull knife to demold castings. Mold is temporary and must be used immediately.

CASTING INTO THE MOLD

All alginate molds will deteriorate quickly. It is recommended that you cast into the mold within 4hours following demold. Materials commonly cast into alginates include LiquiStone™ Gypsum Cement,duoMatrix™ NEO (polymer modified gypsum, available from Smooth-On), wax, clay and very fast urethane resins (such as Smooth-Cast® 300Q). For Soft “Skin-Like” Castings you can cast FUN Silicone™ soft silicone
rubber into BucketGel™ 390 molds to make realistic hands or other body parts.
