Poliya Zero 321 Unsaturated Polyester Resin<\/h3>\n

321-ZERO<\/strong> is a non-shrinkage unsaturated polyester resin<\/strong> designed for rapid mold making. This resin is thixotropic and contains accelerators and fillers. Polya Zero 321 Unsaturated Polyester Resin<\/strong> hardens quickly and completes the curing process due to its special formulation. As a result, problems such as shrinkage, rotation or deformation do not occur in the molds. This resin also eliminates the effect of fiber traces behind the gelcoat and creates a glossy and glassy surface.<\/p>\n

Highlights<\/strong>:<\/strong><\/p>\n

    \n
  1. No shrinkage<\/strong>: Due to the lack of shrinkage, it completely maintains the dimensions of the models.<\/li>\n
  2. High speed<\/strong>: Unlike conventional polyester resins, there is no need to wait between layers, saving up to 80% in time and labor costs.<\/li>\n
  3. Low emission<\/strong>: Due to the low styrene content and LSE structure (low styrene emission), it significantly reduces the emission of gases.<\/li>\n
  4. Glossy surfaces<\/strong>: Ideal for producing glossy and mirror-like molds.<\/li>\n
  5. High mechanical and thermal resistance<\/strong>: Molds produced with Polya Zero 321 unsaturated polyester resin have high mechanical and thermal resistance and have a long service life.<\/li>\n
  6. Can be used for manual and spray methods<\/strong>: Suitable for manual and spray gun use.<\/li>\n<\/ol>\n

      \n
    • Color<\/strong>: Tan<\/li>\n
    • Density<\/strong>: 1.38 g\/cm3 (according to ISO 1675 standard)<\/li>\n
    • Viscosity<\/strong>: 800-900 centipoise (according to ISO 2555 standard)<\/li>\n
    • Monomer percentage<\/strong>: 31-35%<\/li>\n
    • Gel time (in winter)<\/strong>: 25-35 minutes at 23\u00b0C with 2 ml MEK-P<\/li>\n
    • Gel time (in summer)<\/strong>: 40-45 minutes<\/li>\n<\/ul>\n

      Steps of use (for making molds) Standard)<\/strong>:<\/strong><\/p>\n

        \n
      1. Gelcoat application<\/strong>: Use Polijel F\/P 220 gelcoat 600-800 microns thick in at least two coats with 1-2% MEK-P.<\/li>\n
      2. Surface mesh<\/strong> and Polipol 321-ZERO<\/strong> are applied over the gelcoat.<\/li>\n
      3. Fiber layering<\/strong>: 5-6 layers of 300 g\/m2 glass fiber or 4-5 layers of 450 g\/m2 with Polya Zero 321 unsaturated polyester resin (in a “wet-on-wet” manner).<\/li>\n
      4. Repetition<\/strong>: After cooling, the previous steps are repeated again.<\/li>\n<\/ol>\n

        For high-performance molds<\/strong> (such as RTM molds and Thermoform), Polijel F\/P 272 gelcoat and products such as Polives 701-TA are used.<\/p>\n

        Important notes<\/strong>:<\/strong><\/p>\n

          \n
        • To maintain the non-shrinkage properties of Polya Zero 321 unsaturated polyester resin, at least 3-4 layers of 450 g\/m2 or 4-5 layers of 300 g\/m2 of glass fiber should be applied “wet on wet” in one step.<\/li>\n
        • At temperatures below 15 \u00b0 C, satisfactory results will not be achieved.<\/li>\n<\/ul>\n
