META-ACRYL-SL

SLOW CURING ACRYLIC SYSTEM

META-ACRYL-SL Crystal clear transparency slow cure 30-45min cure time. Also unlike epoxy resins, the ratio of the various acrylic parts (powder to liquid) can be altered by up to 25% with no adverse effect to the final properties of the mount. This is because both the liquid and powder are acrylics with various additives and curing agents. The advantages of mounting with acrylics resins include: - Rapid mounting - Very repeatable and consistent mounts - Moderate shrinkage - Good hardness - Semi-transparent - High odor

Mixing Ratios Thoroughly Tested For Best Results.

The mixing ratios were done with a scale or scoops:

Cold Mounting systems are recommended for mounting specimens that are sensitive to high pressures and temperatures. Epoxy products provide good physical adherence, low shrinkage, and excellent infiltration into pores.

Acrylics are easy-to-use resins with short curing times, minimal shrinkage, and excellent mounting properties. They are well-suited for both serial mountings of irregularly shaped specimens and for routine work or single specimens. Acrylics are available with and without a mineral filler. The dye can be used if color coding is needed. When mixing acrylic resins, it is recommended to add powder to the liquid (hardener) – this will result in the most uniform resin mixture. - Castable acrylics are easy to use and are very robust. The main advantage of mounting with castable acrylics is the fast curing time. Depending upon the mixing ratio, castable acrylic mounts are typically ready to use within 8-15 minutes. Also unlike epoxy resins, the ratio of the various acrylic parts (powder to liquid) can be altered by up to 25% with no adverse effect to the final properties of the mount. This is because both the liquid and powder are acrylics with various additives and curing agents. By varying the ratio of the liquid to powder, the curing time and viscosity can be altered. The powder contains a catalyst that reacts with the liquid hardener to start the curing process. Fillers are added to increase hardness and to reduce shrinkage.
