Butyl acrylate is a liquid (5 hPa at ∼ 20 °C) under normal environmental conditions.
At equilibrium in the environment, butyl acrylate will partition primarily to air (95%) with the balance to water (5%).
In air, butyl acrylate will be removed by reaction with photochemically produced hydroxyl radicals (28 h half-life) and ozone (6.5 days half-life).
In water, butyl acrylate is relatively stable to hydrolysis at acidic and neutral pHs (half-life ≥ 1100 days) but will slowly volatilize to air (Henry’s law constant of 21.9 Pa m–3 mol−1 at 25 °C) or be biodegraded (58–90% removal in 28 days).

For over 45 years, Gantrade has built lasting relationships worldwide, based on our ability to deliver quality products like BA consistently and cost-effectively.
Let's take a look at why BA holds a special place in the market for acrylate esters.
Other major acrylate esters include methyl acrylate (MA), ethyl acrylate (EA), and 2-ethylhexyl acrylate (2-EHA).
Butyl acrylate is used as a “soft-monomer” to improve low temperature properties and toughness.
The major markets for BA are in paint & coatings, such as architectural and automotive coatings, followed by adhesives and sealants market.
Other application areas include inks, textile, paper and leather finishes, and caulks.
With a low homopolymer glass transition temperature of -45°C, BA is used in copolymers to improve flexibility, softness, and low temperature properties.
BA exhibits superior photostability and is a preferred monomer where weatherability and sunlight resistance are required.
Another significant and growing segment for BA is in thermoplastic ethylene acrylate copolymers (EAC), at BA levels up to 35 % in copolymers.
EBA copolymers are used as a impact modifier and processing aid in thermoplastics improving properties such as toughness, flexibility, molding characteristics and part appearances.
End use applications include packaging, multilayer films and adhesives.
The molecular structure of BA is shown below:
Combinations of butyl acrylate with other polymerizable monomers such as methyl methacrylate, styrene, vinyl acetate, acrylic acid, and other acrylate ester monomers allow the design of thousands of copolymer compositions.
BA copolymer formulations often contain four or more different co-monomers.
In this manner, the performance profiles of copolymers can be tailored to meet a broad range of end-use requirements.
As a cost-effective, low Tg “soft” monomer, BA is the co-monomer of choice to balance the hardness and softness, tackiness and block resistance, low temperature flexibility, strength and durability, and other key properties to facilitate end-use goals in the marketplace.
For polymers, the Tg is one of the most important parameters in controlling performance.
The Tg is the temperature at which the polymer transitions from a hard and glassy state to an elastomeric, soft and viscous state, when increasing the temperature.
This transition is reversible, in that the material will return to its hard and glassy state when cooled below the Tg. So the location of the Tg influences many attributes, including surface properties, flexibility, hardness, strength, and the minimum film-forming temperatures.
The minimum film-forming temperature of an acrylic latex is the lowest temperature at which the emulsion system uniformly coalesces to form a continuous film.
But even with a fixed Tg, copolymers with different monomer combinations vary significantly in the properties of the final system.
Butyl acrylate is the principle acrylic ester monomer polymerized with methyl methacrylate, styrene, and vinyl acetate monomer to obtain the requisite degrees of hardness, flexibility and toughness in a copolymer system. MMA (Tg 105°C) and styrene (Tg 100°C) increase hardness and cohesive strength and reduce tack. In the copolymer composition, BA (Tg -45°C) increases flexibility, toughness, elongation, tack, and low-temperature properties.
Increasing the BA content will also reduce the minimum film forming temperature to below room temperature.
The copolymerizations are easily carried out using free radical polymerization techniques in an emulsion, solution or suspension process.
Low amounts of functional comonomers, such as acrylic, methacrylic or itaconic acids and hydroxyethyl acrylate/methacrylate are incorporated in the final composition to increase adhesion, facilitate crosslinking and in the case of emulsion systems, increase the latex stability.
Self-crosslinking chemistry based on diacetone acrylamide (DAAM) and adipic acid dihydrazide (ADH), known as keto-hydrazide crosslinking, represents the most advanced technology for controlled crosslinking of acrylic latex polymers.
It begins with copolymerizing low levels of DAAM into a copolymer followed by crosslinking through the pendant ketone moieties with ADH. To learn more about the advantages of DAAM and ADH from the team at Gantrade, see our article on technology of DAAM and ADH crosslinking in acrylic polymers.

The reaction is conducted with deferred introduction of part of the butanol at the top of the distillation column (2) or to the decanter (3) or to the reactor (1), the butanol/acrylic acid molar ratio being initially between 0.5 and 1 before rising to between 1 and 1.5 following the completion of the deferred introduction of the butanol.

Butyl acrylate is of low acute toxicity with an LD50 (rat) of 3730 mg/kg.
In rodent models, butyl acrylate is metabolized by carboxylesterase or reactions with glutathione; this detoxification produces acrylic acid, butanol, and mercapturic acid waste, which is excreted.
A Material Safety Data Sheet has been compiled for butyl acrylate that contains up-to-date information on all questions relevant to safety.
