BR-1041MB is a biobased polyether urethane methacrylate oligomer with a substantial amount of biobased content and is tin-free. This is a harder version of BR-1043MB. This oligomer has a good balnce of toughness and flexibility. It has the ability to adhere to a variety of plastic substrates. The biobased backbone, methacrylate functionality and tin-free nature make this an excellent choice for consumer applications with low irritancy.

Tack-free gel polish top coats are highly desired in the nail coating industry because they provide a durable, high-gloss finish to a manicure without an IPA wipe step. Removing this step from the process saves time and allows the coating to exhibit its natural gloss. Like all nail coatings, tack-free top coats require a gloss finish, superior hardness, and most importantly, low yellowing properties. Bomar has developed a model formula using a new oligomer which provides exceptionally low colop in a tack-free top coat. The model formula requires this new oligomer, a trifunctional methacrylate monomer, a difunctional methacrylate monomer, and photoinitiatop. The formula performed exceptionally well when compared to competitor top coats in areas of yellowness, viscosity, and hardness.

BRC-843SD1 is a difunctional, hydrophobic urethane acrylate which can be formulated to be used in heavy-duty industrial and commercial applications. The resulting tough film makes a functional, nonyellowing, protective single-coating that extends the substrates use-life. BRC-843SD1 is a softer and more flexible version of BRC-843. This oligomer is also tougher then BRC-843. The low water absorption and alkaline resistance make this oligomer perfect for specialty applications in the following industries: aerospace, appliance, automotive, electronic, and medical device.

BR-146, a high molecular weight, trifunctional, aliphatic polyether urethane methacrylate, provides low formulation viscosity and moderate elongation with nonyellowing properties appropriate to soft touch glass coatings and impact resistant coatings. BR-146 shows adhesion to a variety of substrates, making it a candidate for consideration in mixed surface adhesion applications.

BR-741D is a low-molecular—weight, difunctional, aliphatic polyester urethane acrylate that can be effectively formulated for adhesion to cold rolled steel, glass, PMMA, PET, PC, and stainless steel. The resulting hard and tough film makes an effective protective glossy coating which will be nonyellowing, abrasion resistant, and have good weatherability. This is the low-viscosity version of BR-741.

BR-3741AB is a 1.3 functional aliphatic polyether urethane acrylate. The extremely flexible nature of BR-3741AB makes it an excellent candidate for consideration in UV light-curable PSAs as a reactive tackifier. It is also used as a co-oligomer for adhesion promotion in coatings.

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.

BR-582 is a 2.4 average functional aliphatic polyether urethane acrylate. As with other BR-500 series materials, BR-582 is designed to offer a balance of benefits between toughness and flexibility. While only slightly lower in tensile strength and hardness than BR-571, BR-582 has almost double the total elongation at break. BR-582 responds quickly to UV cure, owing to its elevated functionality.

BR-5413MB is a difunctional aliphatic polyether urethane methacrylate with a good balance of high tensile strength and impact resistance. Formulating with linear monofunctional monomers can yield improved flexibility. This oligomer is an excellent candidate to consider for use in impact resistant coatings, and provides low color and excellent non-yellowing performance.

BR-581MT is an oligomer blend that provides a low color, tack-free cure under low-intensity LED cure conditions. BR-581MT provides a balance of hardness and flexibility for abrasion resistance on flexible substrates, while also yielding a high-gloss, non-yellowing finish. This product is a resin blend containing 25% DEGDMA, is tin-free, is fully INCI listed, and can be formulated into a tack-free top coat for nail gel applications.

BRC-842MB is a difunctional, hydrophobic urethane methacrylate that can be formulated into chemical and temperature resistant coatings and resins. The material has low color and excellent adhesion to a wide variety of plastics. The material can be formulated into tough, impact resistant 3D printing resins with excellent flexibility. Its ultra-low water absorption makes this an excellent choice for moisture sensitive or hydrophobic applications.

BRC-8430E is a reduced-functionality version of BRC-843S that provides improved flexiblity and reduced modulus compared with BRC-843S. The hydrophobic and temperature resistant backbone of BRC-8430E combined with the low modulus make BRC-8430E an excellent candidate for moisture resistant adhesives, coatings, and resins, as well as formulations that need to pass autoclave or 85/85 testing.

BR-542MB is a difunctional, aliphatic polyether urethane methacrylate. BR-542MB is used for its desirable balance of toughness and flexibility and its ability to adhere to a variety of substrates. As a primary oligomer, BR-542MB offers excellent properties of adhesion and optical clarity. As a co-oligomer, BR-542MB can be used to improve an existing formulation's glass adhesion.

BRC-441D is a difunctional, hydrophobic urethane acrylate that can be formulated into chemical and temperature resistant coatings and resins. The material has low color and excellent adhesion to a wide variety of plastics. The material can be formulated into tough, impact resistant 3D printing resins with excellent flexibility. Ifs ultra-low water absorption makes this an excellent choice for moisture sensitive or hydrophobic applications.
