HK Research R0229 - Thermoset Polyester - Casting

Knowde Enhanced TDS

Identification & Functionality

Chemical Family: Isophthalics,
Peroxides,
Polyesters,
Unsaturated Polyester (UPE)
Polymer Name: Thermoset Polyester
Plastics & Elastomers Functions: Resin
Technologies: Plastics
Product Families: Plastics — Thermoset Resins
Polyesters

Features & Benefits

Materials Features: Excellent Retention,
Fast Curing,
Good Color Stability,
Good Stain Resistance,
Medium Viscosity,
Superior Clarity,
UV Stabilized
Features: R0229 is supplied at a medium-low viscosity to facilitate good filler wet-out as well as promote more rapid air release. R0229 is UV Light-Stabilized to further enhance the color stability of the densified castings made from this resin. R0229 has been further modified with a blend of Styrene and acrylic monomers to improve durability of the finished part.

Applications & Uses

Markets: Building & Construction,
Industrial
Applications: Building & Construction — Building Materials
Interior Fixtures,
Other Building Materials
Industrial — Chemical & Industrial Manufacturing
Tooling & Moldmaking
Cure Method: Chemical Cure
Plastics & Elastomers Processing Methods: Casting
Applications: The Table that follows illustrates some suggested formulas using various fillers along with R0229 resin and the catalysts we have recommended. The gel and cure times seen with the RJ
Marshall fillers are very similar to those you might obtain with the same fillers in a BPO-Cured resin system. The gel and cure times using this resin and the Durastone filler are significantly faster than those we have obtained with either the BPO-Cured or regular MEKP-cured 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.

Properties

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.
