Storage

Store in a dry place at room temperature. RECKLI PUR-Elastomer A_x001d_40 amp; is storable for _x001e_6 months from delivery when kept in the closed original packaging at about 18°C. Opened drums must be closed airtight right after use.

Processing

Each contact with moisture must strictly be avoided. Before processing, the base component has to be stirred up thoroughly. Add the hardener (B) to the base component (A) and mix them homogenously. Transfer the mixture into a second receptacle and stir it up again. Thereby the incorporation of larger amounts of air should be avoided. Once mixed the processing of the material must be completed within the pot life (15 - 20 minutes). The shortest demoulding time is 24 hours.

Surface Preparation

The model surface must be dry and clean. Absorbing surfaces should be sealed to facilitate the subsequent demoulding and to avoid inaccurate curing. For this, RECKLI PUR-Sealant can be used if the surface is solvent-resistant. Otherwise, especially if the surface has to be recovered in the original state, RECKLI Si- Stripping Lacquer can be applied and removed with water along with all residues after completing the molding works. Afterwards, 2– 3 layers of RECKLI Mold Wax are applied. Each layer has to dry completely.. When applying several layers of elastomer, the preceding layer should be still slightly sticky but sufficiently cured to bear the load of the following application. If the surface is completely cured, it must be roughened by grinding before further material can be applied.
