who has solutions that really stick? we do
Ashland's synthetics, cellulosic and guar-based polymers are typically employed as binders, rheology modifiers and tack enhancers in latex-based and water-soluble adhesives.
In these systems, Ashland's natrosol™ hydroxyethyl cellulose and aquaflow™ water soluble polymers deliver superior performance in thickening, improving sag resistance, increased cohesion and adhesion, as well as in achieving the required viscosity.
Aqualon™ & blanose™ carboxymethyl cellulose are an excellent choice for non-staining wallpaper adhesives, delivering a thick, smooth, and clear paste with superior adhesion properties.
Polyvinylpyrrolidone, pvp/va™ and gantrez™ products are commonly used as binders in glue sticks, providing safe and superior adhesive performance.
Polyvinylpyrrolidone, PVP/VA, klucel™ hydroxypropyl cellulose and aqualon™ ethylcellulose are also used in solvent borne, hot melt, pressure sensitive, re-moistenable and re-pulpable adhesives.
In addition, dextrol™/strodex™, easy-wet™ and surfadone™ surfactants are excellent wetting agents. Drewplus™ foam control agents are great defoamers in water-based adhesive formulations.
V-Pyrol™ (N-vinyl-2-pyrrolidone) and V-Cap™ (N-vinyl-caprolactam) are versatile reactive diluents for free radical radiation-curable adhesives, with use on a wide variety of substrates. Both monomers provide unique benefits as reactive diluents, such as increased curing speed, improved adhesion, enhanced hardness and tensile strength.

natrosol™ hydroxyethylcellulose (HEC)
Natrosol™ hydrdoxyethylcellulose (HEC), a nonionic, water-soluble polymer, is a white, free-flowing granular powder. Solutions of Natrosol™ HEC are pseudoplastic or shear-thinning. Natrosol™ HEC is easily dissolved in cold or hot water to give crystal-clear solutions of varying viscosities. Furthermore, low to medium molecular weight types are fully soluble in glycerol and have good solubility in hydro-alcoholic systems containi...
aquaflow™ hydrophobically modified polyacetal-polyetthers
Aquaflow™ rheology modifiers are nonionic synthetic associative thickeners. Thickening results from self-association and association with the latex particles. They are surface active, stable over a broad pH range (4-12), and more salt tolerant than commercial HEURs (hydrophobe-modified ethoxylated urethanes). The aquaflow™ product line contains both high-shear and low-shear nonionic thickeners.
pvp va polymers and co-polymers
Polyvinylpyrrolidone/vinyl acetate (pvp/va) resins are linear, random copolymers produced by the free-radical polymerization of the monomers in ratios varying from 70/30 to 30/70 vinyl acetate to vinylpyrrolidone. Pvp/va copolymers are available as white powders or clear solutions in ethanol, isopropanol and water. Polymers in the four ranges of vinylpyrrolidone content (30, 50, 60 and 70 percent), are produced in ethanol or isopropanol. The pvp/...
gantrez™ polymers
Gantrez™ polymers (a-425, es-225, es-335, es-425, es-435, sp-215) are a series of copolymers of monoalkyl esters of poly (methyl vinyl ether/maleic acid) with varying ester groups, supplied as clear, viscous solutions. The gantrez™ polymers form tough, clear glossy films. Films exhibit tack-free adhesion, have excellent substantivity, and moisture resistance. Film properties and solubility can be modified by the type and degree...
gantrez™ polymers
Gantrez™ polymers (a-425, es-225, es-335, es-425, es-435, sp-215) are a series of copolymers of monoalkyl esters of poly (methyl vinyl ether/maleic acid) with varying ester groups, supplied as clear, viscous solutions. Gantrez™ polymers are soluble in alcohols, esters, ketones and glycol ethers and have good compatibility with aerosol propellants. They can also be used in both low and high VOC formulations.
dextrol™ and strodex™ phosphate esters and specialty surfactants
Dextrol™ and strodex™ phosphate ester surfactants are leading technologies within our ever-expanding portfolio of high-performance additives. Dextrol™ and strodex™ surfactants have been developed for high performance in a variety of end-use applications by engineering specific chemistries under precisely controlled reaction conditiions. Dextrol™ and strodex™ are unique mono- and diester phosphates as well as sp...

surfadone™ wetting agent
Surfadone LP-100 wetting agent is a low-foaming, nonionic rapid wetting agent with an HLB of 6 and having no critical micelle concentration (CMC). Due to the electron delocalized lactam ring, Surfadone LP-100 wetting agent interacts with anionic surfactant micelles. This greatly enhances its water solubility, resulting in a synergistic surface tension reduction and wetting enhancement at low concentrations.
drewplus* foam control agents
Take control of your foam with Drewplus* foam control agents Drewplus* foam control agents (FCA) from Ashland are leading technologies within an ever-expanding portfolio of additives that improve the performance of decorative paints and industrial coatings, as well as water-based adhesives, graphic art systems, polymers and polymer dispersions Drewplus* foam control agents are formulated without the use of alkylphenolethoxylates (APEO) and are av...
klucel™ hydroxypropylcellulose (HPC)
Klucel™ hydroxypropylcellulose (HPC) is a nonionic cellulose ether that is soluble in both cold water and polar organic solvents. Available in a wide range of molecular weights and particle sizes, klucel™ can be used in a variety of solvents or solvent combinations, and is particularly fomulated in solvent based and hot melt adhesives.
natrosol™ plus hydrophobically modified
Natrosol™ Plus hydrophobically modified hydroxyethylcellulose (HMHEC) delivers all the benefits of Natrosol B HEC along with outstanding spatter resistance and improved high-shear viscosity. Natrosol Plus HMHEC is an associative thickener and thickens through multiple mechanisms. In addition to the hydrogen-bonding and chain entanglement, typical of standard HEC, Natrosol Plus is hydrophobically modified and readily forms weak, three-dimens...
natrosol™ b hydroxyethylcellulose
Natrosol™ B hydroxyethylcellulose (HEC) delivers all the benefits of standard Natrosol HEC, but in addition, offers enzyme resistance (biostability). This best-in-class, bio-resistant HEC will maintain stability even in the presence of cellulose enzyme produced by microbial activity.
