Abstract
A joint compound which remains flexible upon curing and therefore tailored for manufactured housing processes, comprising an acrylate, a biocide, a reinforcing agent, a latex, a first surfactant, a plasticizer, a coalescent agent, a fungicide, a filler, and a second coalescent, all materials being present in predetermined weight percents. A method for producing flexible joints is also provided whereby joints formed by abutting panels are sealed with a joint compound, said joint compound having the characteristic of remaining flexible upon curing or setting.
Claims15
A joint compound which remains flexible upon curing and which is overlaid with wet film while still wet comprising:
- a.) an acrylate resin in a weight percent selected from a range of between approximately 40 percent and 60 percent;
- b.) an incan preservative in a weight percent selected from a range of between approximately 0.10 percent and 0.15 percent;
- c.) a polyamide fiber in a weight percent selected from a range of between approximately 0.5 percent and 3.0 percent;
- d.) a latex in an amount of approximately 20 percent by weight of said acrylate resin:
- e.) a surfactant in a weight percent of between 0.1 and 0.2;
- f.) a plasticizer in a weight percent selected from between approximately 0 and 8 percent;
- g.) a filler in a weight percent selected from a range of between approximately 0 and 35 percent;
- h.) a pyrithione in a weight percent selected from a range of between approximately 0.18 and 0.20 percent;
- and
- i.) an ester alcohol in a weight percent selected from a range of between approximately 0.5 and 2.0.
A method for producing flexible joints comprising:
- a.) supplying a first planar substrate having a first edge;
- b.) abutting a second edge of a second planar substrate against said first edge of the first planar substrate, thereby forming a joint;
- c.) applying a predetermined amount of a joint compound to the joint to provide a seamless surface, said joint compound having the characteristic of remaining flexible upon curing and consisting essentially of an acrylate resin in a weight percent of between approximately 40 and 60 percent, an incan preservative in a weight percent of 0.10 and 0.15, a polyamide fiber in a weight percent of 0.5 and 3.0, a latex in an amount of approximately 20 percent by weight of said acrylate resin, a surfactant in a weight percent of between 0.1 and 0.2, a plasticizer in a weight percent of between 0 and 8, a filler in a weight percent of between approximately 0-35, a pyrithione in a weight percent of 0.18 to 0.20, and a coalescent in a weight percent of between approximately 0.5 and 2 percent;
- and
- d.) finishing the seamless surface by applying a wet coating to the seamless surface 15 minutes after the said seamless surface is created.
A joint compound which remains flexible upon curing comprising:
- a.) an acrylate resin in a weight ratio of acrylate resin to compound of 47.2 percent;
- b.) an incan preservative in a weight ratio of incan preservative to compound of 0.11 percent.;
- c.) polyamide fiber in a weight ratio of fiber to compound of 1.5 percent;
- d.) a latex in a weight ratio of latex to compound of 9.4 percent;
- e.) a surfactant in a weight ratio of surfactant to compound selected from a range of between approximately 0.18 and 0.19 percent;
- f.) a plasticizer in a weight ratio of plasticizer to compound of 6.2 percent;
- g.) calcium carbonate in a weight ratio of calcium carbonate to compound of 32.1 percent;
- h.) a pyrithione in a pyrithione to compound weight ratio selected from a range of between approximately 0.18 and 0.20 percent;
- and
- i.) polyacrylate microspheres in a microsphere to compound weight ratio of 2.9 percent.
