If you see a chemical compound with the "ol" as a suffix its an alcohol. You can have a low molecular weight alcohol like methanol (CH₃OH) or a high molecular weight alcohol like glycerol (CH₂OH·CHOH·CH₂OH). What they all have in common is what chemists call a functional group - in this case it's the OH group - called a hydroxyl group. The number of hydroxyl groups determine whether it's an alcohol or a polyol (containing more than one hydroxyl groups). The most common ones are what chemists call the lower alcohols. In order of increasing molecular weight they are: - Methanol. ... Ethanol. ... Pure, (undenatured) alcohol .... SDA [which] is the most important commercial from of ethanol. ... Industrial alcohol. ... CDA [which] is completely denatured alcohol .... Propanol. ... Butanol.  4, record 3, English, - lower%20alcohol

Kraton G series 1657 rubber is used as an additive to low molecular weight resins such as Regalrez 1094. When using Kraton rubber always be sure to use Tinuvin 292. The rubber improves the flexibility of a final varnish, improves scratch resistance and increases the varnishes viscosity which yields a better feeling varnish when applying by brush (low molecular weight resins tend to feel very thin). Kraton G 1657 can be added in the range of 1-3% by weight of resin. One helpful hint, Kraton rubber does not dissolve well in low aromatic solvents, try pre-dissolving the Kraton rubber in a small amount of high aromatic solvent such as xylene.  3, record 5, English, - high%20aromatic%20solvent
