EP1150 Flexible Urethane Rubber

GENERAL DESCRIPTION:  EP1150 is a two-component, urethane elastomer (rubber) suitable for making molds for concrete and plaster casting.  It has also been used to make rubber parts such as gaskets and squeegees.  EP1150 provides the following outstanding features:

                (1)           Extremely low viscosity

                (2)           Convenient volumetric mix ratio

                (3)           Rapid set time for high productivity

                (4)           No odor

                (5)           Excellent reproduction of even the finest detail

                (6)           Pleasing translucent waxy color (can be pigmented or dyed)     

                (7)           Tough, tear-resistant  character  

Recommended mix ratio is 50 parts of A with 50 parts of B by volume or weight. This provides a 6 minute pot life, and a 16 hour demold time. Pot life and demold time will vary depending on temperature and casting thickness. Full cure is 24 hours.

The resultant room temperature cured elastomer has these properties:

                                Specific Gravity                    1.04

                                Hardness                               50 A

                                Tensile Strength                   320 psi

                                Elongation                             400%

                                Shrinkage                              Negligible

                                Max. Use Temp.                   140°F

                                Viscosity, mixed                   700 cps

EP1150 is available in the following sizes:

                                2 Pint Kit                2 lb

                                2 Quart Kit             4 lb
