DECAR BUTYL is a colourless, slightly hygroscopic high boiling liquid with a mild odour. It is completely miscible with water and most organic solvents. In addition, it has good solvent power for nitrocellulose and can be diluted to a considerable extent with organic solvents. It forms binary azeotropic mixtures with some organic substances.

DECAR BUTYL is an excellent solvent for nitrocellulose, celluloid, Colophony, Manila copal, benzoin resin, chlorinated rubber, polyvinyl ethyl ether, polycarylates; for phenol formaldehyde, urea formaldehyde, melamine formaldehyde and malelic resins and for Uresin B (carbamate resin). It readily dissolves essential oils and a number of dyestuffs. The only vegetable oils dissolved are castor oil and oiticica oil.

DECAR BUTYL effectively dissolves the common plasticizers.

Dammer, rubber, bitumen, polystyrene and polyvinyl chloride (for lacquers), polyvinyl carbazole, fats and most vegetable oils are insoluble in DECAR BUTYL while polyvinyl acetate, polyvinyl butyrals, and coumarone resins dissolve in it only with difficulty. DECAR BUTYL swells shellac, cellulose, acetate, vinyl acetate, vinyl chloride, dicarboxylic acid, copolymers, polymethacrylates and cellulose acetobutylrate.


DECAR BUTYL has an extremely slow rate of evaporation and thus, it a marked increase in drying time is to be avoided, the amounts permissible in fast drying nitrocellulose and cellulose ether lacquers are very small. The additional of DECAR BUTYL to such lacquers improves their flow and gloss.

When mixed with other solvents of low volatility, DECAR BUTYL is eminently suitable for inclusion in paints and printing inks as these should remain moist and soft over a long period.

Additions of up to 5% of DECAR BUTYL may be made to stoving lacquers as phenol formaldehyde and urea formaldehyde lacquers without notably increasing their drying time. Even if appreciably smaller amounts are added, the flow properties and gloss of such lacquers are much improved.

DECAR BUTYL may be added to air-drying lacquers to produce good brushing out properties. In this way very satisfactory lacquers with a particularly high gloss may be obtained. It should be remembered that DECAR BUTYL can considerably retard the thickening of lacquers containing hardening agents (i.e. improve the pot life).
