BDMA (Benzyldimethylamine) Epoxy Accelerator
CAS: 103-83-3
Benzyldimethylamine (BDMA) is a tertiary amine accelerator used to speed up the cure of epoxy resin systems cured with anhydrides, polyamides, or other amine hardeners. Even at low loadings (0.5–2 phr), BDMA dramatically reduces cure time and temperature, enabling faster production cycles. It is particularly effective in anhydride-cured epoxy systems for electrical laminates, potting compounds, and transformer coatings.

Bisphenol F Epoxy Resin (DGEBF)
CAS: 28064-14-4
Bisphenol F Epoxy Resin (DGEBF) is a diglycidyl ether of bisphenol F with significantly lower viscosity than bisphenol A analogues, making it ideal for solvent-free, high-solids formulations. Its lower viscosity enables superior filler loading and improved wetting in adhesives, coatings, and composites. Cured DGEBF systems exhibit improved chemical resistance to solvents and acids compared to BPA-based resins.

Butyl Glycidyl Ether (BGE) Reactive Diluent
CAS: 2426-08-6
Butyl Glycidyl Ether (BGE) is a monofunctional reactive diluent for epoxy resins that reduces viscosity while participating in the crosslinking reaction upon cure, thus avoiding the plasticizing effect of non-reactive diluents. It is widely used to reduce the viscosity of high-MW epoxy resins for solvent-free coatings, adhesives, and composites without significantly compromising mechanical or chemical resistance. BGE exhibits moderate reactivity and is miscible with most epoxy resins and curing agents.

C12–C14 Alkyl Glycidyl Ether Reactive Diluent
CAS: 68609-97-2
C12–C14 Alkyl Glycidyl Ether is a monofunctional reactive diluent derived from natural C12–C14 fatty alcohols, offering very low skin sensitization potential compared to short-chain glycidyl ethers while still effectively reducing epoxy resin viscosity. It participates in the cure reaction to build a flexible, resilient network, improving the impact resistance and peel strength of cured adhesives. Its bio-based origin and improved toxicological profile make it a preferred choice for safety-conscious formulators.

C5 Aliphatic Hydrocarbon Tackifier Resin
CAS: 68131-77-1
C5 Aliphatic Hydrocarbon Resin is a thermoplastic tackifier polymerized from C5 piperylene and isoprene fractions obtained from steam cracking of naphtha. It provides excellent compatibility with natural rubber, SIS, and SBS block copolymers, significantly boosting tack and peel adhesion in hot-melt and solvent-based PSA formulations. Its light color, good thermal stability, and low odor make it preferred for labeling, packaging, and hygiene product adhesives.

C9 Aromatic Hydrocarbon Tackifier Resin
CAS: 64742-16-1
C9 Aromatic Hydrocarbon Resin is a thermoplastic tackifier produced by cationic polymerization of vinyl aromatic monomers (styrene, vinyltoluene, indene) from the C9 fraction of naphtha cracking. It imparts high tack, excellent adhesion to polar substrates, and good compatibility with SBS, SBR, and neoprene rubbers. C9 resins are widely used in solvent-based adhesives, printing inks, and rubber compounding where higher aromatic content and amber color are acceptable.

CTBN (Carboxy-Terminated Butadiene-Acrylonitrile) Liquid Rubber
CAS: 68891-46-3
CTBN Liquid Rubber is a carboxy-terminated butadiene-acrylonitrile copolymer used as a reactive toughening agent for epoxy adhesives and structural composites. When reacted with epoxy resins, CTBN phase-separates to form rubber domains that arrest crack propagation, leading to dramatic improvements in fracture toughness (KIc), peel strength, and impact resistance with minimal sacrifice of stiffness or heat resistance. It is widely employed in aerospace structural adhesives, automotive body adhesives, and electronic underfills.

Calcium Carbonate Filler for Adhesives (Coated GCC/PCC)
CAS: 471-34-1
Coated Calcium Carbonate (GCC/PCC) is the most widely used extender filler in adhesive and sealant formulations, providing volume extension, viscosity adjustment, and improved dimensional stability at low cost. Surface coating with stearic acid or other fatty acids improves compatibility with polymer matrices and reduces moisture uptake. In silicone, polyurethane, and MS polymer sealants, fine-particle coated CaCO3 contributes to smooth extrusion, good surface finish, and balanced mechanical properties.

Calcium Oxide (Quicklime) Moisture Scavenger
CAS: 1305-78-8
Calcium Oxide (CaO, quicklime) is a high-capacity inorganic moisture scavenger used in moisture-sensitive adhesive, sealant, and encapsulant formulations to extend shelf life and prevent premature cure. It reacts irreversibly with water to form calcium hydroxide, making it highly effective even at very low moisture levels. Fine-grade CaO is used in organic electronics encapsulants (OLED), one-component epoxy films, and polyurethane formulations where residual moisture must be minimized.

Cationic UV-Curing Epoxy Oligomer
CAS: 25068-38-6
Cationic UV-Curing Epoxy Oligomer is an epoxy-functional resin designed for cationic photopolymerization initiated by diaryliodonium or triarylsulfonium salts. Unlike acrylate UV systems, cationic epoxy cure continues after UV exposure (dark cure), resulting in very low shrinkage, excellent adhesion to metals and glass, and outstanding chemical resistance. These systems are used in high-performance optical, electronic, and industrial UV adhesive applications requiring dimensional precision and chemical durability.
