HT 45 Transparent (45 ShA)

Instructions for use

Take the two bi-component products supplied by Zhermack (base and catalyst) and shake before use. Weigh an equal amount of catalyst and base (ex. 100 grams of catalyst and 100 grams of base; within a 5% error range the end result is not altered. Once the product is weighed and it is assured that the base and catalyst are equal, the two components are inserted in a recipient and mixed thoroughly. It is important to check while mixing that no residue remains on the base and sides of the recipient. Mix energetically until the colour of the product is homogeneous. Once the product is mixed it is poured, preferably 30cm above the recipient into the mould. The working time is approximately WT (see table below) from the beginning of the mixing at 23°C. It is advised to vacuum the mixture to prevent air pockets. If the quantity used is less than what is needed to complete the duplication, complete the hardening of the silicone and than proceed with the addition of the remaining silicone needed. The material attaches to the silicone without altering the final result.

The setting time (time the silicone needs to vulcanize) is about ST at 23°C (see table below). After the ST is complete, from the start of the mixing, we can separate the model from the mould. If necessary use compress air to facilitate this separation. It is important not to force this separation with sharp objects that can deform the final stamp. The silicon rubber is compatible with all gypsums, coatings, polyurethane resins and acrylic resins

Note: The working time and thus the setting time are reduced if the temperature exceeds 23°C (ex. If the temperature is 40°C, the working time is halved and the setting time is approximately halved). If the temperature is less than 23°C both the working time and setting time increase considerably. (ex. If the temperature is 4°C, the working time doubles and the Setting time increases three times the minutes indicated at 23°C ).
