ACRYLIC RESINS

INTRODUCTION

"Elvacite" acrylic resins are polymers or copolymers of methyl methacrylate or other acrylic monomers for use in solvent-applied lacquers, inks, adhesives and specialty coatings*. The "Elvacite " resins offer the distinctive combination of properties associated with high-quality acrylic coating resins:

Outstanding resistance to ultraviolet degradation
Excellent weatherability
Superior abrasion resistance
Excellent resistance to water, alcohol, dilute acids and alkalies, chemical fumes and corrosive and oxidizing environments
High gloss and hardness
Generally low pigment reactivity
Water-white color and transparency
Resistance to discoloration on heating

"Elvacite" resins are available as minute spherical beads in grades that differ widely in such properties as hardness, flexibility, solubility and solution viscosity. Compatibility with a variety lf film formers and plasticizers permits further modification to achieve the exact properties desired.

The "Elvacite" resins are thermoplastic. They are thermally stable up to 177-232°C (351-450°F), will above their softening range. At higher temperatures, i.e., about 260°C (500°F) or above, they undergo smooth depolymerization to monomers, leaving negligible ash.

"Elvacite" acrylic resins have a wide range of molecular weight, flexibility and functionality, and are particularly will suited for protective and decorative coatings for plastics,metals, concrete,wood and paper

TABLE Ⅰ "Elvacite" Acrylic Resins
"Elvacite"Grade Numbers	Polymer Type	Typical inherent Viscosity^a	Molecular Weight	Principal Characteristics and Uses
2008	Methyl methacrylate	0.18	Low	Lowest molecular weight grade. Used in lacquers and gravure inks requiring low viscosity at high solids. Highest tack temperature. Good pigment dispersion.
2009	Methyl methacrylate	0.39	Medium	A more soluble,softer version of "Elvacite" 2010. Shows unusual chip resistance for a hard polymer.
2010	Methyl methacrylate	0.40	Medium	General purpose grade for lacquer coatings such as barrier topcoatings for vinyl fabric. High tensile strength and hardness.
2013	Methyl/n-butyl methacrylate copolymer	0.17	Low	Fast-dissolving. low-viscosity grade with quick solvent release for use in industrial lacquers, aerosols, inks, and coatings for plastics. Softer than the methyl methacrylate polymers.
2014	Methyl methacrylate copolymer	0.40	Medium	Softest and most flexible of the "Elvacite" copolymer resins. Good pigment wetting. Useful for clear, translucent or pigmented metal lacquers, e.g., for aircraft. Also
2016	Methyl/n-butyl methacrylate copolymer	0.25	Low	Fast dissolving, low viscosity general purpose resin for lacquer and toner use.
2021	Methyl methacrylate	0.50	High	A higher molecular weight version of "Elvacite" 2010 for better abrasion resistance in vinyl topcoats.
2028	Methacrylate copolymer	0.24	Low	Unique in its broad solubility and compatibility. Designed for flexographic inks, general purpose lacquers and metal coatings.
2041	Methyl methacrylate	1.25	Very High	The highest molecular weight grade. Used in barrier topcoating of vinyl fabric for dielectric heat sealability,maximum abrasion resistance, block resistance and slip.
2042	Ethyl methacrylate	0.83	Very High	Tough, alcohol-tolerant, broadly compatible grade for use in abrasion-resistant coatings such as high-gloss clear lacquers for decals and outdoor signs. Slightly softer than "Elvacite" 2013.
2043	Ethyl methacrylate	0.21	Low	Fast-dissolving, low-viscosity resin with alcohol solubility for flexographic inks. Most compatible grade. Has excellent pigment wetting ability and broad solubility for use in lacquers for solvent-sensitive substrates. Equal in hardness to "Elvacite" 2042.
2044	n-Butyl methacrylate	0.52	High	Softest, most flexible bead grade. Useful in adhesives for smooth plastic films and aluminum, and in silk screen inks. Will plasticize and improve adhesion of harder butyl grades ("Elvacite" 2045 and 2046) and nitrocellulose. lmproves outdoor durability lf vinyl chloride resins in pigmented lacquers.
2045	lsobutyl methacrylate	0.64	High	Hardest of the weak-solvent-soluble butyl grades. Useful in topcoats for vacuum metallized plastics and in lacquers for other solvent-sensitive substrates. Softer than "Elvacite" 2042 and 2043
2046	n-Butyl/isobutyl methacrylate 50/50 copolymer	0.54	High	Medium-hardness butyl grade. Soluble (like "Elvacite" 2044 and 2045) in mineral spirits. VM ＆ P naphtha, and some alcohols. Useful in aluminum finishes, ceramic coatings. and aerosol snows.
2550	Methyl/n-butyl Methacrylate copolymer	0.32	Medium	Soft, flexible grade with excellent adhesion to metal substrates. Useful in staple cement applications because of flexibility.
2552	Methacrylate copolymer	0.34	Medium	Unique resin designed for general metal finishes where high depth of gloss is important. Resists cracking and glazing in multiple coat systems. Also useful for high gloss coatings on plastic substrates. Excellent resistance to UV degradation and has excellent exterior durability
2614	methyl/n-butyl Methacrylate copolymer	0.21	Low	Low odor version of 2013 without sulfur containing compounds. Fast dissolving grade with quick solvent release useful in industrial lacquers, inks, and coatings for plastics.
