ACRYSOL DR-130

ACRYSOL DR-130 is a synthetic, liquid thickener that provides a low cost/high performance alternative to cellulosic thickeners in interior flat latex paints. The rheology modifier provides application and feel properties very similar to high molecular weight grades of cellulosic thickeners. It is easy to handle and incorporate into paint and is highly resistant to microbial attack.

ACRYSOL RM-5000

ACRYSOL RM-5000 is a non-ionic urethane rheology modifier, based on a new solvent-free technology with improved binder reactivity. It provides excellent flow and leveling, high film build, combined with excellent water and alkali resistance. It is recommended in a wide range of matte through high gloss paints and lacquers. It can be used either alone or in combination with thickeners effective in the low shear range to reach the desired balance of flow and sag resistance. It can be used as a sole thickener in high gloss paints to achieve optimum flow properties.

GBL Gamma Butyrolactone LAB GRADE 99%

Gamma-Butyrolactone (γ-butyrolactone or GBL) is a hygroscopic colorless liquid with a weak characteristic odor which is soluble in water. GBL is a common solvent and reagent in chemistry as well as being used as a flavouring, as a cleaning solvent, as a superglue remover, and as a solvent in some wet aluminium electrolytic capacitors. In humans it acts as a prodrug for GHB, and it is used as a recreational intoxicant with effects similar to alcohol.

 

GBL has been found in extracts from samples of unadulterated wines. This finding indicates that GBL is a naturally occurring component in some wines and may be present in similar products. The concentration detected was approximately 5 μg/mL and was easily observed using a simple extraction technique followed by GC/MS analysis. GBL can be found in cheese flavourings but typically results in a content of 0.0002% GBL in the final foodstuff.

 

GBL is a lactone. It is hydrolyzed under basic conditions, for example in a sodium hydroxide solution into sodium gamma-hydroxybutyrate, the sodium salt of gamma-hydroxybutyric acid. Under acidic conditions it forms an equilibrium mixture of both compounds. These compounds then may go on to form a polymer. When treated with a non-nucleophilic base, like lithium diisopropylamide, GBL can become an alpha-carbon nucleophile. The related compound caprolactone can be used to make a polyester in this manner.

GBL is not active in its own right; its mechanism of action stems from its identity as a prodrug of GHB. The hypnotic effect of GHB is enhanced by combination with alcohol. A 2003 rat study showed that GBL in combination with ethanol showed a potentiated hypnotic effect, as the sleep-timing measure was longer than both of the individual components combined
