JAYHAWK BTDA: Five Decades of Proven Performance
3,3′,4,4′-Benzophenone tetracarboxylic dianhydride (CAS# 2421-28-5)
Since its commercialization in the 1970s, BTDA has been the performance benchmark for demanding applications. Why do formulators continue choosing BTDA? Because BTDA consistently delivers.
In Epoxy Systems: Transform standard resins into high-performance solutions. BTDA-cured epoxies achieve glass-transition temperatures exceeding 200°C while maintaining superior insulation, wear resistance, and corrosion protection. Applications include:
- Magnet wire enamels for electric motors and transformers
- Coating powders for busbars, switchgear, and stators
- Potting compounds protecting sensitive electronics
In Polyimide Systems: Enable continuous operation above 350°C. BTDA-based polyimides maintain exceptional dielectric performance in the most demanding environments:
- Flexible circuits in smartphones, tablets, and wearables
- Lightweight aerospace engine components
- Stealth technology for aircraft and marine vessels
Why JAYHAWK BTDA? We pioneered commercial BTDA production and remain the only supplier offering multiple grades tailored to modern requirements. Made-in-USA with secure supply chains. REACH-registered. Regularly audited by customers and regulatory agencies. When you specify JAYHAWK BTDA, you’re choosing reliability backed by decades of proven performance.
JAYHAWK 6FDA: Performance for Next-Generation Applications
4,4′-(Hexafluoroisopropylidene) diphthalic anhydride (CAS# 1107-00-2)
Advanced aerospace, electronics, and medical applications demand advanced materials. 6FDA delivers fluorinated performance that conventional dianhydrides can’t match, and Jayhawk is the only supplier offering commercial-grade 6FDA with an exclusive made-in-USA supply chain.
Where 6FDA Makes the Difference:
- Aircraft engines requiring maximum fuel efficiency and range
- Solar cell substrates with enhanced UV resistance and dielectric properties
- Colorless films for foldable smartphone and industrial displays
When your application pushes boundaries, 6FDA pushes back.
JAYHAWK PMDA: Time-Tested Reliability
Pyromellitic dianhydride (CAS# 89-32-7)
Some applications don’t need the latest innovation, they need proven reliability. PMDA’s compact, rigid structure has served epoxy coating powders, polyimide molding compounds, and film applications for decades. It also functions as an effective chain extender for polyester thermoplastics.
JAYHAWK Crosslinkers: Versatile Chemistry for Hybrid Systems
JAYHAWK 301 (2-Allylphenol, CAS# 1745-81-9) A compact crosslinker with dual allyl and hydroxyl functionality. Combine acrylic, bismaleimide, epoxy, phenolic, or polyurethane resins to create specialty coatings and laminates with precisely tailored properties.
JAYHAWK 302 (2,2′-Diallyl bisphenol A, CAS# 1745-89-7) The traditional choice for crosslinking 4,4′-bismaleimidodiphenylmethane. Multiple hydroxyl and allyl reactive sites make it ideal for epoxy-phenolic hybrids in advanced composites.
JAYHAWK 303 (1,3-Phenylene-bis-oxazoline, CAS# 34052-90-9) Novel oxazoline ring chemistry that opens thermally or catalytically for free-radical crosslinking. Imparts exceptional thermal resistance and flame retardancy to bismaleimide, epoxy, polyester, and polyimide systems. Also functions as a chain extender for polyamide and polyester thermoplastics.
Ancillary Products
JAYHAWK NBE (n-Butyl ether, CAS# 142-96-1) Non-reactive, low-polarity, slow-evaporating solvent carrier/transport medium for industrial adhesives. Additive carrier for release agents. Flow modifier. Low odor.
