The product is a very soft elastic polyurea casting compound. ebalta GM 951-1 is suitable as a flexible casting system in the field of mold- and tooling for parts which require low shore hardness and high tear propagation resistance due to deep under cuts. Mold temperatures of about 60 °C lead and/or curing at 60°C, to faster curing and therefore short demoulding time. Demoulding can be reduced to 30-45 min. To achieve final properties as fast as possible, postcuring can be made at 60°C for 6-8 hrs. and after curing at room temperature. For complete curing of the parts, any non-postcured molds should only be employed after 2-3 days. Any non-observance may lead to shorter pot life. The potlife of GM 915-1 can be shortened by mixing hardener GM 951-1 with hardener GM 900-1 (see mixing table) For individuell formulation of the shore hardness, GM 900-1 can be mixed with GM 951-1 (see mixing table). With the A-component GM 951-1 Thix a spreadable surface resin can be obtained.
