- Applications
The Table that follows illustrates some suggested formulas using various fillers along with R-0228 resin and the catalysts we have recommended. The gel and cure times seen with the Marshall fillers are very similar to those you might obtain with the same fillers in a BPO-Cured resin system.
The suggested starting formulas that follow have been tested in our laboratories and all exhibit the following outstanding features:
- Excellent air release without vacuum processing.
- Outstanding stain resistance - Low ANSI stain ratings.
- Rapid cure and fast Barcol hardness development - no post-cure required.
- Excellent initial clarity and color retention.

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.
