  • Mix the two components thoroughly in the ratio indicated.
  • If fine details are to be reproduced, a thin layer of mixed resin and hardener should be applied to the mould surface using a short bristle brush before casting.
  • Evacuated material will improve properties. Post-curing will improve final properties.

Safety & Health

Safety Information
  • It is generally quite harmless to handle provided that certain precautions normally taken when handling chemicals are observed.
  • The uncured materials must not, for instance, be allowed to come into contact with foodstuffs or food utensils, and measures should be taken to prevent the uncured materials from coming in contact with the skin, since people with particularly sensitive skin may be affected.
  • The wearing of impervious rubber or plastic gloves will normally be necessary; likewise the use of eye protection.
  • The skin should be thoroughly cleansed at the end of each working period by washing with soap and warm water.
  • The use of solvents is to be avoided. Disposable paper - not cloth towels - should be used to dry the skin.
  • Adequate ventilation of the working area is recommended.
  • These precautions are described in greater detail in the Material Safety Data sheets for the individual products and should be referred to for fuller information.
