Epovion BPA-SOL 13 is a solvent-based bisphenol-A epoxy resin solution supplied as an 80% solution in xylene, obtained from an intermediate-molecular-weight bisphenol-A and epichlorohydrin resin dissolved to a workable application viscosity. Epovion BPA-SOL 13 is characterized by excellent miscibility with pigments and fillers, good adhesion, and water resistance once cured, and can also be used as a modifier for other epoxy resins to improve elasticity, impact strength, and adhesion.
Epovion BPA-SOL 13 Overview
Epovion BPA-SOL 13 is manufactured by first reacting bisphenol-A with epichlorohydrin to build an intermediate-molecular-weight epoxy resin, then dissolving that resin in xylene to a fixed 80% solids content. This intermediate epoxy equivalent weight, higher than that of standard liquid bisphenol-A resins, gives cured films from Epovion BPA-SOL 13 a different balance of flexibility and hardness, while the xylene carrier keeps the solution at a workable viscosity for brush, roller, or spray application.
Because it is supplied pre-dissolved in solvent, it is easy to incorporate into coating and adhesive formulations without the need for high-shear mixing or heating equipment often required to dissolve solid epoxy resin flakes or pellets. This makes it a convenient choice for formulators seeking the mechanical and chemical resistance benefits of an intermediate-weight epoxy resin without the added handling complexity of solid resin forms.
Key Features
- Ready-to-Use Solvent Solution: Supplied as an 80% solution in xylene, Epovion BPA-SOL 13 eliminates the need for on-site dissolution of solid epoxy resin.
- Excellent Pigment and Filler Miscibility: Epovion BPA-SOL 13 disperses readily with pigments and fillers, supporting smooth, well-formulated coating systems.
- Good Adhesion and Water Resistance: Cured films based on this resin solution provide good adhesion to common substrates along with solid water resistance for protective coating use.
- Modifier for Other Epoxy Systems: Epovion BPA-SOL 13 can be blended into other epoxy resin formulations to improve elasticity, impact strength, and adhesion.
- Low Color for Clear and Light-Colored Finishes: A Gardner color below 1 supports clear or lightly tinted coating and laminate finishes.
Typical Applications
Epovion BPA-SOL 13 is used in insulating and protective coatings, laminate coatings, and adhesives, where its solvent-solution form simplifies formulation and application compared with solid epoxy resin grades. Its intermediate epoxy equivalent weight makes it a useful complement to standard liquid bisphenol-A resins in formulations that require additional flexibility, impact resistance, or improved adhesion to challenging substrates.
As a modifier, it is often blended into standard liquid epoxy systems at varying ratios to fine-tune cured film properties, particularly where a formulator needs to improve impact strength or flexibility without switching to an entirely different resin chemistry. In laminate coatings and electrical insulation applications, the resin’s good adhesion and water resistance support long-term protective performance in humid or outdoor-exposed environments.

Blending ratios between a solvent-solution modifier resin and a standard liquid epoxy base often require small-scale trial formulation to confirm the resulting film properties meet target flexibility, hardness, and adhesion goals, since the interaction between two different epoxy equivalent weights can shift cure behavior in ways that are not always linear or fully predictable from the individual resin specifications alone.
Storage Recommendations
Epovion BPA-SOL 13 should be stored in tightly sealed drums at ambient temperature, away from open flame and ignition sources given its xylene solvent content, and protected from moisture ingress that could affect resin clarity and reactivity. Because this product contains a flammable aromatic solvent, storage areas should follow standard flammable-liquid warehousing practices, including adequate ventilation and separation from oxidizing materials.
Formulators should periodically check solvent content and viscosity of stored material, since solvent loss through container leakage or repeated opening can gradually raise the effective solids content and viscosity of the remaining material, affecting application properties. Containers should be resealed promptly after each use, and partially used drums should be used within a reasonable timeframe to avoid solvent evaporation issues.
Coating and laminate formulators qualifying a new lot of solvent-based epoxy resin solution typically verify solids content, viscosity, and color against the certificate of analysis before large-scale use, particularly when the resin will be blended with other epoxy components at defined ratios. Confirming these parameters upfront helps avoid unexpected shifts in coating film build, cure time, or appearance that can otherwise only be detected after a full production batch has already been formulated and applied.
Solvent-based epoxy resin solutions are widely used in industrial coating and laminate operations where equipment for melting and dissolving solid resin flakes is unavailable or impractical, particularly in smaller formulation shops or field-applied coating work. The trade-off for this convenience is the need to manage solvent emissions and flammability throughout storage, transfer, and application, which typically requires updated safety data documentation and, in some regions, specific volatile organic compound reporting depending on local air quality regulations.
Packaging & Transport
Epovion BPA-SOL 13 is supplied in 220 kg drums as standard packaging, with bulk options available for larger-volume customers. As a flammable solvent-based product, Epovion BPA-SOL 13 is classified and transported in accordance with applicable hazardous goods regulations, and customers should ensure receiving facilities are equipped to handle and store flammable liquid shipments appropriately. Customers with specific pack-size or bulk logistics requirements are encouraged to contact our sales team to discuss the most suitable supply arrangement.
Epovion BPA-SOL 13: Safety & Handling
Given its xylene solvent content, Epovion BPA-SOL 13 requires standard flammable-liquid handling precautions, including elimination of ignition sources, adequate ventilation, and the use of chemical-resistant gloves and eye protection to minimize skin and eye contact with both the epoxy resin and solvent components. Facilities using Epovion BPA-SOL 13 should maintain appropriate spill-containment measures and ensure operators are trained on safe solvent-handling procedures.
Formulators comparing solvent-based options such as Epovion BPA-SOL 13 against solvent-free liquid resins like Epovion BPA-L 12E should weigh the application convenience of a ready-to-use solution against considerations such as solvent emissions, flammability, and VOC regulations applicable to their specific coating or laminate application. Operators should always review the current Safety Data Sheet before handling Epovion BPA-SOL 13 for the first time.
