Technical Data Sheet MPC-195
Product Description
MPC-195 is a 100% solids, low exotherm two component epoxy casting system. It is ideal for deep pour casting for river tables, jewelry and embedding applications. Its long work time and low mixed viscosity helps avoid excess air entrapment and allows for excellent flow in tight crevices and around complex shapes. This product contains no VOC and when mixed/cured properly meets the requirements for direct food contact by the Canadian Food Inspection Agency.

Areas of application
- Casting tables
- Embedding and encapsulation
- Casting jewelry and arts & crafts
Packaging
MPC- 195 is offered in the following kit sizes:
- 3-gallon kit (7.56L resin (A) and 3.78L hardener (B))
- Bulk and special packaging also available upon request
Metallic pigments are offered in 6 oz containers (1 pigment pod per 3-gallon kit)
Surface Preparation
Remove dust, dirt, grease, oil and all other contaminants with proper cleaner/degreaser. A seal coat is recommended on porous material to help prevent air bubble release during the curing process.
Mixing and Product Application
Warm up the resin and hardener to 24 – 27 °C. This will improve the flow characteristics and bubble release. In a dry, clean container mix 2 parts of resin with 1 part of hardener. Be sure to scrape the sides and bottom of the mixing container while mixing. Mix for 3-4 minutes using a paint paddle. After mixing, transfer the mix into a similar mixing container and mix again for another 1-2 minutes.
Pour material into the mold. Wait 15 – 20 minutes then lightly pass a lit propane torch over the surface at a 45°-degree angle with the tip of the torch being at least 6 inches from the surface until all bubbles are gone. The carbon dioxide at the end of the flame helps facilitate bubble release and popping the bubbles. This will help ensure a glass like finish. If latent bubbles exit, a similar torching at 30 minutes may be needed. Drips may be sanded off after the item has cured.
Pour the epoxy to a maximum of 3” thick per layer. For large volume pours, maximum thickness should be reduced, and multiple pours are recommended. Mix only the amount that you need at one time and pour the mixture within 15 minutes. Unused resin and hardener should be left in original containers. Mix exact amounts of both resin and hardener in separate mixing cups. Do not add more hardener than resin, as this will cause the finished coating to remain sticky. Inaccurate measuring will cause epoxy surface to remain soft or sticky spots on the epoxy surface.
Clean equipment with xylene. Once the product has hardened, it may only be removed mechanically.
Product Restrictions
- MPC-195 should be stored in a dry place between 24° C and 27° C
- Keep out of the sun and out of reach of children.
- Resin and hardener should not be left in an open container.
- Application should be used where humidity is under 60% and temperature is between 21°- 29°C.
- Use a de-humidifier if needed.
- MPC-195 should be used within one year of purchase.
- Surfaces may discolor in areas exposed to regular ultraviolet light.
- When properly mixed and cured, this epoxy system is safe for direct food contact. However, because the customer is mixing/pouring, each mixture/application would have to be assessed individually to say if it is 100% food safe.
