Principal Properties & Application:
ALITA 850 resin is an ortho-phthalic unsaturated polyester resin synthesized from phthalic anhydride, maleic anhydride, and standard diols. It is pre-dissolved in crosslinking monomers such as styrene and features low viscosity and low reactivity.
ALITA 850 resin is characterized by low shrinkage, excellent toughness, high whiteness, and minimal water streaks. It has a wide range of applications, suitable for general resin crafts, imitation jade crafts and also for stone repair.

Instruction and attention:
- ALITA 850 resin contains wax and catalysts.
- ALITA 850 resin is suitable for general crafts. For items such as imitation crystal, imitation colored glass, and frosted glass crafts, it is recommended to choose ALITA
853 resin.
Handling and Storage:
This resin contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be avoided and necessary protective equipment and clothing should be worn.
Drums – It is highly recommended that all material is stored at stable temperatures below 25°C (77°F). Avoid exposure to heat sources such as direct sunlight or steam pipes. To avoid contamination of product with water, do not store outdoors. Keep sealed to prevent moisture pick-up and monomer loss. Rotate stock.
We provide small samples free of charge, but you will need to cover the shipping costs.
We have our own technical department. After you test the sample, please provide us with your detailed requirements. We can adjust the resin accordingly to enhance the properties of your finished products.
Honestly, it depends on the quantity. We will do our best to create a production plan based on your estimated time of arrival (ETA).
For the first trial order, we require 100% payment upfront. For subsequent orders, we ask for 30% payment in advance and 70% payment after the buyer receives the B/L copy. We also accept L/C if needed.
