Butyl Methacrylate (BMA) Suppliers, Dealers in Mumbai, India

Butyl Methacrylate

Butyl Methacrylate (BMA) is a vital methacrylate monomer. It is renowned for its versatility in industrial applications. It appears as a clear & colorless liquid with a faint fruity or acrylic scent. With its reactive methacrylate functional group as well as butyl ester chain, BMA copolymerizes easily with other monomers & also imparts excellent durability, flexibility & transparency to polymers & coatings. It is favored in adhesives, sealants, coatings, inks & concrete additives. BMA increases performance properties while having low volatility along with improved safety profiles.

What is Butyl Methacrylate?

Butyl Methacrylate, chemically known as butyl 2 methylprop 2 enoate (CAS 97 88 1), is an unsaturated ester derived from methacrylic acid. Its molecular formula is C₈H₁₄O₂, with a molar mass of 142.20 g/mol. Structurally, it features the methacrylate vinyl group (–C=C–) adjacent to a carbonyl ester linked to a four carbon butyl chain.

As a monomer, BMA undergoes free radical polymerization to form poly(butyl methacrylate) (PBMA) or copolymers used in various formulations . It is clear & colorless, slightly volatile. It has a vapour heavier than air. BMA is miscible with many organic solvents as well as only slightly soluble in water (≈ 0.36 g/L at 20 °C).

This monomer brings various benefits:

Durability & toughness – The ester as well as vinyl groups provide high impact resistance & also mechanical strength.

Flexibility – The butyl side chain offers elasticity and weather resilience.

Low volatility & odor – Minimizes emissions and improves handling safety.

Opacity – Best choice for optical clarity in coatings & films.

Reactivity – This copolymerizes with acrylates, isocyanates, epoxies, etc., offering versatility.

Many common applications include paints, coatings, adhesives, sealants, inks, concrete additives as well as modifiers in plastics.

Handling and Storage

Flammability safety: Flash point ~50–54 °C; vapour forms explosive mixtures (LEL: 2 %, UEL: 8 %).

Ignition sources: Keep away from sparks, open flames, and hot surfaces. Use explosion-proof equipment.

Ventilation: Ensure good airflow; avoid vapor accumulation in low areas.

Protective equipment: Use gloves, glares & if needed, appropriate respirators as well as full-face protection.

Spill management: Try to absorb with inert materials (sand, vermiculite), collect as well as seal in proper containers.

Storage conditions: Store in tightly sealed containers, in a cool (ideally 2–8 °C or < 30 °C), dry, well ventilated area. Diminish exposure to heat and light.

Polymerization alert: Avoid heat, moisture, oxidizers. Materials like acids as well as bases can cause polymerization.
