FLAME RETARDANT, POLYESTER RESIN

 

DESCRIPTION:                    HETRON FR620T-20 resin is a low viscosity, prepromoted, thixotropic, flame retardant                                                        polyester resin. Composites made with HETRON FR620T-20 resin have been tested and                                                     achieved a. flame spread of 5.25 (ASTM E-84) without a synergist such as antimony trioxide.

 

PERFORMANCE:               

• Excellent wet-out
• Low drainage
• Class I flame retardancy without antimony.
• Less than 35% styrene

 

SUGGESTED USES:             HETRON FR620T-20 resin can be used in hand lay-up, spray-up and filament winding                                                         flame retardant applications. Markets include the transportation, electrical, mining and                                                        building construction industries.

 

ALTERNATIVE USES:       HETRON FR640T-20 resin is recommended when a synergist is used to achieve a Class I                                    flame spread. For corrosion requirements, call 1-800-327-8720 for specific recommendations.

'HETRON polyester resin will burn if provided with a sufficient amount of heat and oxygen. The degree of flame retardancy of the cured polyester resin composites is characterized by the ASTM £-84 tumid test. This test if performed under strictly controlled conditions where aflame spread rating is assigned according to comparisons with test set-point materials. The behavior of the cured composite under these controlled conditions can vary from an actual fire situation.

Resistance to UV radiation may be improved by adding up to 1.0% maximum CYASORB x6 UV-9 ultraviolet screener to the resin for the exterior exposed surface.

 

For all surfaces that will be exposed to air during fabrication (top-coating patching, exterior surfaces, etc.,) the addition of 0.4% paraffin wax to the final resin layer is recommended. A waxed surface might affect secondary bonding and flame retardance.

HANDLING:   HETRON FR620T-20 resin contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be avoided and necessary protective equipment and clothing should be worn,

 

Ashland Chemical Company maintains Material Safety Data Sheets on all of its products. Material Safety Data Sheets contain health and safety information for your development of appropriate product handling procedures to protect your employees and customers.

 

Our Material Safety Data Sheets should be read and understood by all of your supervisory personnel and employees before using Ashland Chemical Company's products in your facilities.

 

 

RECOMMENDED STORAGE:

Drums - Stare at temperatures below 80°F.  Storage life decreases with increasing storage temperature. Avoid exposure to heat sources such as direct sunlight or steam pipes. Some thixotrope settling may occur with prolonged storage.  Mild agitation will redisperse thixotrope. Keep containers sealed to prevent moisture pickup and monomer loss. Rotate stock.

 

Bulk - Store in stainless steel tanks lined with epoxy or phenolic coatings. Observe precautions against heat and moisture (see above). An inert gas or nitrogen blanket may be desirable.

 

SHELF LIFE: This product has a limited shelf life. When stored in accordance with the above conditions, this product has a minimum shelf life of three months.
