What you should know about tert-Butyl Acrylate (TBA)?

tert-Butyl Acrylate (TBA) with the molecular formula of C7H12O2 is an acrylate monomer [1]. It imparts hydrophobicity, chemical stability, hardness, scratch resistance, weatherability, hardness and crosslinking properties to polymers. It forms homopolymers and copolymers. Its copolymers can be prepared with acrylic acid and its salts, amides and esters, and with methacrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, unsaturated polyesters and drying oils, etc. It is also a very useful feedstock for chemical syntheses, because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds. It is listed on REACH, TSCA, DSL, CHEMINV, IECSC, AICS, ENCS, ISHL, ECL, NZIOC, PICCS and NECSI inventory[2].

Applications

Features & Benefits

tert-Butyl Acrylate (TBA) is a monofunctional monomer with a characteristic high reactivity of acrylates and a bulky hydrophobic moiety. tert-Butyl Acrylate (TBA) can be used to impart the following properties to polymers:

•  Chemical resistance
•  Hydrophobicity
• Hardness
• Scratch resistance
• Adhesion
• Heat resistance
• High solids
• Weatherability
   

Storage & Handling

In order to prevent polymerization, tert-Butyl Acrylate (TBA) must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. It has to contain a stabilizer and the storage temperature must not exceed 35 °C. Under these conditions, a storage stability of one year can be expected upon delivery. In order to minimize the likelihood of overstorage, the storage procedure should strictly follow the “first-in-first-out” principle. For extended storage periods over 4 weeks it is advisable to replenish the dissolved oxygen content.

The preferred construction material for tanks and pipes is stainless steel. Carbon steel is also acceptable, although the formation of rust may be a problem with product quality (color). Iron(III)-ions have been shown to be a weak polymerization initiator. If carbon steel is to be used, special procedures should be used to prepare the tank for use. Storage tanks, pumps and pipes should be earthed.
