as has been indicated , the formulations of the present invention employ an internally plasticized vinyl acetate - ethylene copolymer . these copolymers are commercially available , and their preparation disclosed in u . s . pat . nos . 3 , 708 , 388 and 3 , 844 , 990 . the internally plasticized feature is provided by the utilization of crosslinking elements in the polymer which are chemically integrated into the polymer , but yet offer flexibility because of their composition . these materials are distinguishable from externally plasticized systems which utilize a material which may become fugitive to the polymer after extended periods of exposure to ambient . in addition to internally plasticized vinyl acetate - ethylene copolymers , it has been found that vinyl acetate - ethylene - vinyl chloride interpolymers may also be employed . such interpolymers as well as the method of preparation are disclosed in u . s . pat . no . 3 , 830 , 761 . in addition to the binder material , fillers in the form of calcium carbonate , mica , perlite , or other inert finely - divided solids may be employed . it has been found that the utilization of an internally plasticized material permits the utilization of larger quantities of fillers , thereby enhancing the overall and ultimate stability of the material upon drying or curing . suspension agents , defoamers , as well as thickeners may be utilized if desired . as has been indicated , the formulations provide a working mixture or working suspension which may be applied to the surfaces of dry wall panels , either as a finish material or as a filler - jointing material . the strength and flexibility of the cured product is sufficient so as to eliminate cracking or crazing , and yet is capable of being sanded with conventional sandpaper . for a more complete comprehension of the invention , the following formulations are given as typical and illustrative . in order to prepare a formulation which is adapted for use a jointing - filler material , the following formulation is given : ______________________________________ingredient amount______________________________________internally plasticized vinyl - acetate - ethylene copolymer ; 110 gallonslatex emulsion ( 55 % solids in ( 1001 lbs . ) aqueous solution ) sodium salt of polymericcarboxylic acid 20 lbs . defoamer 10 lbs . calcium carbonate powder 4050 lbs . mica , pulverized powder 375 lbs . cmp acetate 1 lb . cellulose 24 . 5 lbs . water 115 gallons______________________________________ in the above formulation , the suspension agent may be selected from any of a variety of commercial materials , although the sodium salt of polymeric carboxylic acid available under the designation &# 34 ; tamol 850 &# 34 ; of rohm and haas company of philadelphia , pennsylvania has been found useful . as a defoamer , &# 34 ; troykyd powder defoamer 262 &# 34 ; available from troy chemical corp . of newark , new jersey may be utilized , although other conventional defoamers may be found useful . other defoamers which are formed by the addition of propylene oxide to ethylene diamine followed by the addition of ethylene oxide may also be used , such materials being available under the code name &# 34 ; tetronic &# 34 ; from basf wyandotte chemicals corporation of wyandotte , michigan may be utilized . the cmp acetate is utilized to retard growth of organisms which may otherwise thrive in the cellulose product utilized . the cellulose employed may be that formulation sold under the designation &# 34 ; 250 hhxr natrosol &# 34 ;, available from hercules inc . of wilmington , delaware . as has been indicated , the formulation of example 1 may be applied directly to dry wall panels as a jointing and filling material . upon drying , the material may be sanded with conventional sandpaper and only one additional application is normally required . inasmuch as internally plasticized binders are employed , the material remains flexible and thus neither cracks nor crazes upon extended periods of exposure to the ambient . tests have indicated that the material will bend , without cracking , and will further stretch up to 1 / 16th inch in modest thicknesses without fracturing . use of fibrous fillers is not required , and accordingly the presence of undesirable quantities of fiberglass , asbestos , or the like which pose potential hazards to users are avoided . the following formulation has been found desirable as a smooth wall texture coating , particularly adapted for coating on dry wall surfaces : ______________________________________ingredient amountinternally plasticized vinyl - acetate - ethylene copolymer ; latex emulsion ( 55 % solids inaqueous solution ) 90 gallonssodium salt of polymericcarboxylic acid 20 lbs . defoamer 10 lbs . calcium carbonate powder ( 12 micron mean particle size ) 4200 lbs . ground mica particles ( mean size15 microns ) 200 lbs . cmp acetate 1 lb . cellulose 20 lbs . water 110 gallons______________________________________ this material has been found to have excellent film - forming properties , and forms an excellent coating for dry wall surfaces . colors and other pigments may be employed as desired . the following material has been found desirable as a ceiling texture : ______________________________________ingredient amount______________________________________internally plasticized vinyl - acetate - ethylene copolymer ; latex emulsion ( 55 % solids inaqueous solution ) 55 gallonssodium salt of polymericcarboxylic acid 20 lbs . defoamer 10 lbs . calcium carbonate powder ( mean particle size 12 microns ) 3200 lbs . ground mica ( mean particle size15 microns ) 200 lbs . cmp acetate 1 lb . perlite ( 50 % through 12 mesh screen ) 87 lbs . cellulose 22 lbs . water 160 gallons______________________________________ the above material has desirable properties as a ceiling texture , and provides good adhesion and cohesion for such application . the following material has been found desirable as a texture material to be applied to plastic foam ( foamed polystyrene ) panels and also may be used as a crack cover : ______________________________________ingredient amount______________________________________internally plasticized vinyl - acetate - ethylene copolymer ; latex emulsion ( 55 % solids inaqueous solution ) 360 gallonssodium salt of polymericcarboxylic acid 10 lbs . defoamer 10 lbs . cmp acetate 1 lb . titanium dioxide ( 2 micronmean particle size ) 160 lbs .&# 34 ; attagel 50 &# 34 ; attapulgus clay ( average particle size 14 micron )( available from engelhard mineralsand chemicals of edison , new jersey ) 270 lbs . ______________________________________ this material is desirable for use as a texture product to be applied to surfaces of foamed polystyrene , with such material being utilized more widely in the building industry . as has been indicated , interpolymers of vinyl acetate - ethylene - vinyl chloride may be employed . these materials , when utilized , will be substituted on a 1 : 1 basis for the vinyl acetate - ethylene copolymers described above . they are internally plasticized by virtue of the ethylene moiety , and thereby retain flexibility over extended periods of time . it is this ethylene moiety which provides the internal plasticization for both the vinyl acetate - ethylene copolymers and vinyl acetate - ethylene - vinyl chloride interpolymers . the primary purpose of the present invention is to provide a jointing and filling compound for dry wall panels , the invention including the recognition that internally plasticized binders may be employed for this purpose , and with the vinyl acetate - ethylene copolymers providing a surface which is flexible and durable , and also sandable with conventional sandpaper materials . the internally plasticized vinyl acetate - ethylene copolymer emulsions may be employed in an amount ranging from between about 5 %- 25 %, and are normally coupled with water in an amount representing between about 15 % and 40 %, based upon the total product weight . the suspension agent is desirable for maintaining the suspension over extended periods of time . defoamers are conventionally used for avoiding bubbling or frothing of the material upon use . the fillers , as previously indicated , may be utilized in rather heavy quantities , thereby contributing to desirable economic advantages , as well as resistance to crazing and cracking .
