Bomar™ BR-641D is a Polybutadiene (PBD) urethane acrylate, which was designed to meet rigorous electronic coating applications. This oligomer has exceptional adhesion to various metals, glass,and polycarbonate substrates. BR-641D has many desirable properties that are typical to PBD resins, combined with radiation curability. In applications requiring thermal cycling resistance, BR-641D withstands the extremes of temperature typical of such tests, without undue degradation of properties. In addition to the adhesion properties listed in the table below, BR-641D showed excellent adhesion to PMMA, ABS, PVC, Nylon-6, Polystyrene,and Polypropylene.

BR-5541M is a flexible polyether urethane methacrylate oligomer diluted in 20% IBOA with a low modulus, good adhesion to a variety of substrates, and excellent elasticity. The high molecular weight of the backbone structure offers improved elasticity and rebound versus similar high elongation materials. The low modulus of the material allows for a high degree of flexibility comparable to silicone-based materials such as BRS-14320S, but with improved compatibility and surface cure. The compressibility of the material also offers potential usage in gasket and sealing applications.

BOMAR™ BR-970BT is a low molecular weight, difunctional, aliphatic urethane acrylate. BR-970BT can be blended with other oligomers to achieve a balance of toughness and flexibility. BR-970BT offers rapid cure and low yellowing properties where premium performance is required. This material has low skin sensitivity for dental and cosmetic applications.

Bomar™ BR-345 is a difunctional polyether urethane acrylate that provides unique properties for 3D printing resins. This soft material is ideal for use in applications where high elongation is desired, and can be used as an additive for impact resistance. Resins with less than 1000 cps can be formulated with this material when monomer levels are above 50%.

Bomar™ BR-742S is a difunctional, polyester Urethane Acrylate Oligomer that offers good weatherability. High-impact-strength coatings and inks can be formulated that are non-yellowing and have high gloss. This material offers low shrinkage, which is excellent for 3D printing applications. Furthermore, BR-742S is registered with INCI for cosmetic applications.

BR-771F is a low molecular weight oligomer with a good balance of high tensile strength and moderate elongation with an excellent cure speed. BR-771F exhibits excellent adhesion to plastic substrates, particularly polycarbonate. Formulations made with BR-771F can exhibit superior toughness properties with a high Tg. Its inherently low color and aliphatic backbone make BR-771F an excellent candidate for polycarbonate coatings and adhesives

Bomar® BR-744BT is an aliphatic difunctional polyester urethane acrylate offering excellent adhesion, and flexibility. While not limited to the applications, BR-744BT is an effective choice in optical coating for plastics and UV pressure-sensitive adhesives. Provides solvent resistance, is durable, and has high gloss in ink and coating applications. This material has low skin sensitivity for dental and cosmetic applications, and is INCI listed.

Bomar BR-3641AA is an aliphatic polyether urethane acrylate with a high molecular weight and theoretical 1.3 functionality. Films formulated with BR- 3641AA are highly flexible, elastomeric, and tacky. When formulated as an adhesive, this oligomer is excellent as an adhesion promoter or reactive tackifier. This oligomer offers improved adhesion to a variety of substrates.

Bomar BR-202, an aromatic polyether urethane dimethacrylate, finds use in a diverse number of UV coating applications. BR-202 is valued for its strong bond strength, its affinity for glass, steel, and a variety of plastic substrates, and for its excellent elongation. BR-202 is also of value for its low initial color (despite its aromatic nature).

Bomar®BR-742MS is an oligomer that provides excellent acetone removability when used in gel polish hybrid applications. Low heat generation occurs during cure without lamps. The resultant coating also has high gloss, and has low APHA color impact. Furthermore, this oligomer was designed to meet regulatory expectations for retail applicationsin Europe

BR-990S2 is a dual-functional urethane acrylate with isocyanate functional groups. While products formulated with BR-990S2 can be cured with a UV light source, a free isocyanate can also react with ambient moisture to complete the curing process. This UV+moisture curing process will benefit applications where shadow areas are present. BR—990S2 can also be used as a component in a 2K UV+Heat curable product, the other component being a polyol, glycol, or other compound with OH functional groups. A diol, or compound with two OH groups, will exhibit the best properties because it enables chain growth rather than chain termination. BR-990S2 exhibits good flexibility and develops good tensile strength when cured using both UV light and moisture. More flexible products can also be formulated with BR-990S2, different polyols, and UV+heat curing processes.

Bomar BR-3042 is an aromatic polyether urethane diacrylate designed for UV adhesive applications. Cured films of BR-3042 and monofunctional monomers result in soft, highly elongative, tacky systems ideal for use in UV pressure sensitive adhesives (PSA), or UV-curable laminating adhesives.

BOMAR BR-204, an aromatic polyether urethane dimethacrylate, finds use in a diverse number of UV adhesives applications. BR-204 is valued for its strong bond strength, its affinity for glass, steel, and a variety of plastic substrates, and for its excellent elongation. BR-204 is also of value for its low initial viscosity and low color (despite its aromatic nature). It is mainly used in Primer Coatings and Glass Coatings.
