Abstract

Epoxy-polysiloxane based coating and flooring compositions exhibiting improved flexibility, and excellent weatherability and corrosion resistance after curing are described. The epoxy-polysiloxane polymer coating composition may be prepared by combining a polysiloxane, an epoxide resin material and a cure system including a blend of compounds selected from a dialkoxy functional aminosilane, a trialkoxy functional aminosilane, and an amino functional polysiloxane resin, where the blend has an average alkoxy functionality value of 2.0 to 2.8.

Description

— \ — Epoxy siloxane coating compositions FULL DESCRIPTION BACKGROUND The present invention relates to compositions based on epoxy resin /resin / A07M© useful for protective coatings and the like 5” particularly more for epoxy-polysiloxane polymer compositions Epoxy—polysiloxane polymer has the properties of elasticity (uae), 0 weather resistance, reduced shrinkage, corrosion resistance, compressive strength, and chemical resistance, at least comparable to other epoxy polysiloxane coating formulas. Conventional epoxy polysiloxane EPOXY 008109 epoxy coatings are well known and commercially accepted as protective, decorative, galvanizing dds aluminum, wood, and concrete coatings in the marine maintenance, construction, architecture, aircraft, automotive, flooring, and finishing markets. Products The basic raw materials used in the preparation of these coatings generally include the following as basic ingredients (a) epoxy resin 07M “(b) hardener; and (c) pigment; aggregate product; or other components. Epoxide resins are materials that have more than one 0-7 epoxy group per molecule and can be Aide or undoped; aliphatic Cycloaliphatic or heterocyclic Epoxy resins generally contain glycidyl ester or glycidyl ether groups and the weight per epoxide is 8007*108 from 001 to 2.0001. The hardener is typically selected from the general categories of aliphatic amine groups or additional aliphatic amine products; Js Yo polyamides; polyamidoamines cud; Secretary groups

a dala cycloaliphatic amines; aromatic amines ¢ Mannich bases ketimines; and carboxylic derivatives 0015 dyes and agglomerating products include, for example; titanium dioxide and other inorganic and organic color pigments 0; silica 51/168; barium sulfate; magnesium silicate 6; calcium silicate; fumed silica; garnet; feldspar; Carbon black and the like. Epoxy based protective coatings are one of the most widely used methods of corrosion control. They can be used to provide long-term protection to steel and concrete; aluminum” and other structures subjected to a wide range of corrosive conditions from exposure to the atmosphere to complete immersion in strong corrosive solutions. Over lle 01 these coatings have been formulated from either solid or liquid epoxy resin cured with aliphatic polyamine or polycad resin eg Shell Epon 1001 “Jal” or epoxy resin 828 Epon cured with tri-ethylene ( DETA) diethylene triamine cod or Versamid 100 series of polyamides. Vo in two typical beam coating systems; An epoxy resin component is usually a vehicle for a pigment grinding and dispersion of agglomerating products and various additives. Epoxy-based coatings have several properties that make them desirable as coating materials. Coatings are readily available and are applied easily by a variety of Ley methods including spraying, rolling and brushing. It also adheres well to steel, concrete and other substrates.” YS also works and has low levels of Jil Moisture Vapor; They also act as barriers to water, chloride, and sulfate ion ingress. They provide excellent corrosion protection under a variety of weather exposures and have good resistance to many chemicals and solvents. Wal can formulate based materials Epoxy as a material for roofing or flooring primarily Yo to lay over concrete.For example, a flooring material based on

Commercially successful bisphenol A epoxy resin liquid and Jans aliphatic polyamine attached with calibrated silica and agglomerated sand. Some epoxy-based coatings and flooring materials may not show good abrasion resistance in sunlight. While Jie these coatings can maintain their chemical properties© and corrosion resistance; Exposure to the ultraviolet (UV) rays of sunlight can lead to a phenomenon known as chalking, which changes both the color and the sheen of the original paint. when the preservation of color and luster is desirable or required; Protective epoxy coatings are typically with a topcoat that is more resistant to Jie conditions (ull alkyd and vinyl or aliphatic sll polyurethane 00) coatings. The end result is two or three coating systems that provide resistance SSH and weather resistance required; but way too labor intensive and expensive to set up. in addition to; Epoxy-based coatings and flooring materials require resistance to mechanical abuse. For example; Coated materials may be impacted or flexed which may lead to 1 cracking or other defects in the epoxy coating. ERY exposure to atmospheric agents or chemicals can lead to contact with chemicals and underlying surface materials; This may lead (Jia) to oxidation of the substrate and decomposition of the epoxy coating on the underside; and/or release the epoxy coating from the surface. While epoxy-based flooring materials and coatings are gaining acceptance in Lands Glad, the need for epoxy-based materials with JST-improved chemical resistance and resistance to mechanical abuse is still needed (Jie flexing or impact) and color enhancement. or retain luster. Color- and gloss-enhanced epoxy-based coatings and flooring materials are needed anywhere that can be exposed to sunlight. An epoxy coating that does not chalk and does not require a top coat for weather protection is a desirable product. YO chemical, abrasion, impact, bending and abrasion resistant floor coatings optimized for use in both Z and Z containment structures are needed.

A “Although not desiring to be bound by any particular theory; it is believed that the embodiments of the epoxy-polysiloxane coating compositions described in the present application are ripened by: (1) the reaction of the epoxy resin with the curing system to form epoxy polymer chains (Y) hydrolytic polycondensation of a polysiloxane component to produce an alcohol and a polysiloxane polymer, and (©) the copolymerization of epoxy polymer chains with a polysiloxane polymer to form a fully matured epoxy-polysiloxane polymer composition. An aminosilane or an amino-functional polysilane or an amino-functional polysilane is used to form the ripening system; the amine moiety of an aminosilane or an amino-functional polysiloxane undergoes an epoxy-amine addition reaction and the silane moiety of an aminosilane or an amino-functional polysiloxane undergoes polyhydrolytic condensation with Polysiloxane In its mature form, the epoxy-polysiloxane coating composition can exist as a uniformly dispersed composition of linear epoxy chain segments that are cross-linked with a continuous polysiloxane polymer chain, thus forming a polysiloxane chemical structure An interpenetrating polymer network (IPN) has key advantages over conventional epoxy systems. VO when preparing various sample epoxy polysiloxane coating compositions from the present disclosure; The ratio of curing composition to resin component can vary over a wide range. in general; Epoxy resin can be matured using an effective curing system in which amine hydrogen compounds react with the epoxide group of the epoxy resin to form epoxy chain polymers and with polysiloxanes to form polysiloxane polymers; The epoxy chain copolymers and the poly0-siloxane copolymers can be polymerized to form a mature crosslinked epoxypolysiloxane polymer composition. in certain models; The epoxy resin component can be cured using an efficient curing system to provide from 1.7 to 017 eqw of amine per 1 eqw of epoxide. in other models; The epoxy resin component can be cured using an efficient curing system providing from 1.45 to 0.15 eqw amine per 1 eqw epoxide.

vy A- when two or three component system components are combined; The silane crack from the ripening system is believed to condense with a polysiloxane component; The epoxy resin undergoes chain extension by reaction with the related amino groups of the polysiloxane to form a fully matured epoxy-polysiloxane polymer composition. In such a reaction the epoxy resin is believed to act as a cross-link enhancer that adds to the crosslinking density of the formulation without reducing the beneficial properties of the poly©siloxane. Finally; The chemical and physical properties of the epoxy-polysiloxane formulation from the present disclosure can be affected by the careful selection of the epoxy resin; polysiloxane curing system; The ingredients are the ingredients of the dye or the agglomerating substance.
