PACKING AND STORAGE
• The product should be packed into clean, dry, safe and sealed container, net weight 220 Kg.
• Shelf life: 6 months below 25℃, stored in cool and well
ventilated place.
• Any special packing requirement, please contact our support team
NOTE
• All information in this catalog is based on GB/T8237-2005 standard tests, only for reference; maybe differ from the actual test data.
• In the production process of using resin products, because the performance of user products is affected by multiple factors, it is necessary for users to test themselves before selecting and using resin products.
• Unsaturated polyester resins are unstable and should be stored below 25°C in a cool shade, conveyance in refrigeration car or in nighttime, averting from sunshine.
•Any unsuitable condition of storage and conveyance will cause the shortening of shelf life.
INSTRUCTION
• 9952L resin does not contain wax, accelerators and thixotropic additives.
• . The 9952L resin has high reaction activity, and its walking speed is generally 5-7m/min. In order to ensure the performance of the product, the setting of the board travel speed should be determined in conjunction with the actual state of the equipment and process conditions.
• 9952L resin is suitable for light-transmitting tiles with higher weather resistance; it is recommended to choose 4803-1 resin for flame retardant requirements.
• When selecting glass fiber, the refractive index of glass fiber and resin should be matched to ensure the light transmittance of the board.
