Patent ID: 7611654

Claim:
A process for preparing a cement thread repairing composition comprising: combining within a rotating mixer: drinking water, ammoniac solution, dispersant, tripolyphosphate solution, precipitated calcium carbonate, calcium carbonate, and titanium dioxide to form a first solution; mixing the first solution at room temperature within the rotating mixer for approximately 40 minutes; after mixing the first solution, adding styrenated acrylic resin to the first solution within the mixer while the mixer is turned off; adding coalescent, fungicide, and bactericide to first solution and styrenated acrylic resin within the mixer while rotating the mixer and maintaining the contents of the mixer at room temperature for approximately 10 minutes to create the cement thread repairing composition; adding pigmentation to the thread repair composition while rotating the mixer to obtain homogenous distribution of the pigmentation throughout the thread repair composition; and wherein the thread repair composition includes components having the following concentration ranges: drinking water 27-32% ammoniac solution 0.5-0.10% dispersant 0.28-0.38% tripolyphosphate solution 0.3-0.6% precipitate calcium carbonate 16-18% calcium carbonate 16-17.5% titanium dioxide 10-20% styrenated acrylic resin coalescent 2-4% fungicide 0.1-0.2% bactericide 0.1-0.2%.
