• High adhesion ability

Cold Mounting



Cold mounting systems developed toobtain best resultsThe purpose of mounting is to protect fragile or coated materials during preparation and to obtain

perfect edge-retention. Mounting also allows for a safer, more convenient handling of e.g. small,sharp or irregularly shaped specimens or when the protection of layers is imperative.

EpoDye, fluorescent dye to be mixed with the resin toallow for easy identification of pores and cracks whenexamining the specimen in fluorescent light.

Epoxy for no shrinkage – Acrylics for fast curingStruers offers two different types of cold mounting resins, epoxy andacrylic – and your choice of resin is determined by a number offactors such as type of material, specimen characteristics, quantityof specimens, and your quality requirements.

Epoxy resinsEpoxies are ideal for vacuum impregnation of porous specimens,and for high edge-retention requirements. They have the lowestshrinkage of all cold mounting resins. Curing time is relatively long,but the adhesion to most materials is excellent.

Acrylic resinsAcrylics are easy-to-use resins with short curing times, very limitedshrinkage and excellent mounting properties. They are well-suited forboth serial mounting of irregularly shaped specimens and for routinework or single specimens. Available with and without mineral filler.

Vacuum impregnationCertain materials like ceramics, plasma sprayed coatings and speci-mens for failure analysis require special care during preparation.Porosity, gaps, cracks and loose particles can easily be altered oreven removed during preparation if the specimens are not mountedproperly.

In these cases, vacuum impregnation is used to reinforce andprotect the materials. With Struers CitoVac, impregnation is carriedout quickly and efficiently. After curing, the resin reinforces thefragile materials and artefacts like pull-outs and unopened or

smeared pores can be avoided.

CitoVac - for easy impregnation of fragile materials.

AcryDye adds colour to your mounts for easyidentification.

ACCESSORIESAccessories and Drybox, please see separate brochuresfor further details.

Struers’ products are subject to constant product development. Therefore, we reserve ourselves the right to

introduce changes in our products without notice.

Struers offers a large variety of mounting cups and other accessories to provideeasy handling and more accurate specimen preparation.

• Mounting cups in different types and sizes

• Metal spring clips or plastic clips to hold or support small specimens

• Taper section angles for measuring of layer thickness

• Fluorescent dye for microscopic examination under fluorescent light

• Dye for acrylic resins for easy identification of specimens

• Measuring syringes for quick measurement of liquids

• Cups and stirrers

• Electric mixer for optimal mixing of epoxy components

• Wupty tool for pressing mounts out of FixiForm

Drybox – specimen drier and curing ovenTo achieve more uniform mounting results, Drybox can be used to control thetemperature during the curing process. Drybox acts both as a specimen drier anda curing oven.

Accessories

Taper section angles make it much easier tomeasure the thickness of thin layers.

The MultiClips can support up to 5small thin specimens.

Wupty makes it easy to press out themount out of FixiForm.

FixiForm is one of Struers manymounting cups.
