- Uses
- R0213 casting resin is designed for use in the fabrication of flat stock, such as countertops, tabletops and vanities for use with drop-in bowls. The high reactivity, which gives this resin its toughness and chemical resistance, can cause stress cracking if it is cast in bowl molds. Some manufacturers have found that they can successfully cast bowls with this resin if they remove the "hat" very early in the cure cycle and demold the part shortly after it reaches peak exotherm. Both of these steps require extra precautions on the part of the molder.
- R0213 resin will produce castings of excellent color when used with ATH filters such as R. J. Marshall's DF-40 at a filler concentration of 65 - 70% by weight.
- R0213 is supplied at a monomer level and viscosity that would permit the addition of up to 5% by weight of additional monomer such as Methyl Methacrylate. This addition will reduce the viscosity to about 1000-1200 cps and will offer the molder the option of adding an acrylic modification to his system if so desired.
- Filled Resin
- Filled resin tests have not been run on this resin using the 1.75% HiPoint 90 catalyst system specified. We expect to be running these tests in the near future. Meanwhile, we would anticipate, based on our experience with other catalyst systems, that the matrix gel at 77°F will be about 25-30 minutes and the demold time would be approximately 60 minutes from the point of catalyzation.
- R0212 Casting Resin is identical to the R0213 product described in this bulletin except that it is supplied as an unpromoted version of R0213. In order to obtain a reasonable gel and cure of this product it must be suitably promoted prior to catalyzation.R0212 Unpromoted Resin can also be used to blend with the R0213 to lengthen the gel time of the R0213 if required.

Safety & Health
- Safety Considerations
- HK Series Isophthalic Casting Systems are based on a resin, which contains styrene monomer, which is a flammable liquid. Keep away from sparks, heat and open flame (including pilot lights). Electrical equipment should be vapor-proof and protected from breakage.
- Styrene vapors are heavier than air and will tend to concentrate in the low areas of molds and in pockets immediately above the floor area. To keep vapors within a safe limit in all areas, adequate ventilation or suction fans should be used that will remove these styrene monomer vapors.
All equipment must be grounded - including spray guns and molds.
Both the polyester resin and the catalyst may cause burns to eyes and skin. Do not get in the eyes! Avoid breathing vapors! Gel coat applicators should wear a NIOSH approved respirator effective for vapors, spray mist and dust. In case of accidental contact, remove the contaminated clothing and wash affected skin areas with soap and copious quantities of water. Contact a physician if persistent skin irritation occurs. For eyes, immediately flush with plenty of water for at least 15 minutes; call a physician immediately. Wash contaminated clothing before reusing.
