Uses: R0217 casting resin is designed for use in the fabrication of flat stock, such as countertops, table tops and vanities for use with drop-in bowls. The high reactivity, which gives this resinits 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.

R0217 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.

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.
