PRODUCT OVERVIEW

LH-Silicones RTV M 20 are tin-cured silicone rubber two components that have exceptional tear strength and working properties and library life which cured overnight at room temperature with low shrinkage to a strong,flexible silicone rubber. Also,reproduce the finest detail and are suitable for a variety of industrial and art related.

 Applications

 making molds for reproducing prototypes, furniture, sculpture and architectural elements with a variety of materials including wax, gypsum, low melt alloys/metals and urethane, polyester resins:

After addition of a catalyst

RTV M 20                                                      100Parts

Catalyst CA-22                                             2.5Part

Pot life of the catalyed mix(23°C, approx)   25minutes

Demould time           (23°C, approx)   4 hours

After addition of a catalyst CA-35

TV M 20                                                         100Parts

Catalyst CA-35                                             4-5Part

Pot life of the catalyed mix(23°C, approx)    60minutes

Demould time           (23°C, approx)    8hours

IMPORTANT: .If there is any question about the effectiveness of products agent combination, a small-scale test should be made on an identical surface for trial. Increase catalyst will caused cured rubber become crispy.
