Applications & Uses

Intended Uses

Designed and formulated to be incorporated within both thermoset and thermoplastic composites that require fire protection and smoke suppression.

Maximum Processing Temperature

425°F Recommended 450°F Max (Discoloration may occur above this temperature depending upon exposure time.)

Methods of Application

MultiTech Flame Retardant B can be incorporated into a medium by a number of methods:

• Addition of MultiTech Flame Retardant B directly in the polymer resin en masse prior to process fabrication.
• Spraying a filled slurry.
• Applying a highly filled pre-impregnated reinforcement.
• May be blended with a variety of commercially available paints, resins and surface coatings for application onto wood, metal, and plastic.

Features & Benefits

Product Features

• Superior Performance: Extremely effective at the proper loading against open flame and high radiant heat, even in severe fires with high velocity combustion fronts.
• Climate Survivability: Resistant to water, weather, sea spray, chemical attack and protects over a wide range of operational temperatures.
• Versatile: Effective for use in a wide range of ambient fabrication methods and elevated temperature curing; thermoforming; and molding processes as high as 450o F.
• Heat Barrier: This thermally non-conductive and infrared reflective insulating material can extend substrate time to failure by as much as 470% verses unprotected substrates.
• Environmentally Friendly: Non-toxic and may be recycled with thermoplastics. Suppresses smoke normally generated by polymeric resins. Contains no bromine, antimony or magnesium. No PBDEs, PBDDs, PBDFs or other toxins can be formed from this product.
• Ease of Application: Easily incorporates with sheer into a wide variety of thermoset resins. Is easily compounded; heat pressed molded; or thermoformed in pre-produced cast film into a wide range of thermoplastics. Forms an excellent mechanical bond with finished thermoset substrates and thermoplastic mediums.

Cautionary Notes

PEROXIDE INITIATOR USE WITH MultiTech Flame Retardant B

Unsaturated resins are cured using a variety of initiators, depending upon temperature, used for the process. The reactivity of the resin and the use of modifiers, promoters, accelerators, as well as additives, greatly influence the choice of the proper and most correct initiator. Fire Retardants and Smoke Suppressants may each affect the type and concentration of initiator, or initiators required. The selection of initiator, or initiator system, is based upon the rate of cure desired, the extent of working time required (pre-gel time), and the necessary storage time of the resin/initiator-additive mix (pot-life).

When fabricating with MultiTech Flame Retardant B™ at ambient temperature (i.e. room temperature) with polyester, or vinyl ester resin [NOTE: this might include-Open Molding; Closed/clamshell molding; Resin Transfer Molding; Casting; Filament winding; Vacuum Bagging; etc.]:

• MultiTech Flame Retardant B™ is not affected by MEKP (Methyl Ethyl Ketone Peroxide)/Metal Carboxylate (i.e. Cobalt Napthanate) initiator/accelerator systems.

Cautionary Notes

When fabricating with MultiTech Flame Retardant B at elevated tempratures with polyester, or vinyl ester resin: [NOTE: This could include: Pultrusion; Filament Winding; Compression / Bulk Molding; Elevated Sheet Molding; Pre-Preg; etc.

• MultiTech Flame Retardant B is not recommended for use with Diacyl Peroxides (Molding temperatures of 200-270°F / Ex.: BPO.
• AVTEC recommends the use of Peroxyesters. Specifically TAmyl-Peroctoate (Molding temperatures of 210-280°F), 75% liquid concentration in a Plastisizer Solution as an alternative to Benzoyl Peroxide initiation.
• Other Peresters, such as T-Butly-Perbenzoate (Molding temperatures 275-325°F), used to “finish” the part for a complete, hard cure are also recommended with MultiTech Flame Retardant B. This TBPB peroxide is the favored Perester for good surface characteristics.
• Peroxyketals, such as Peroxy-Cyclohexanes (Molding temperatures 265-310F), have very low sensitivity to compounding ingredients and are recommended for use in the intermediate phase of the thermal initiation process to optimize a thorough cure.
