Abstract
Methods, compositions and boat hulls are disclosed using and forming a wood replacement surface. The wood replacement surface is used as a replacement or substitute for wood surfaces. The wood replacement surface of the present invention has improved characteristics, such as strength and water resistance, compared to conventional wood surfaces. The wood replacement surface is resistant to environmental conditions such as water, heat and sunlight. The wood replacement surface is easier to apply than conventional wood surfaces.
Claims20
A method of repairing a wood surface with a wood replacement surface comprising:
- removing a wood surface from a structure to form an area with a removed surface and a remaining surface;
- spraying or pouring a wood replacement composition and a catalyst onto the remaining surface of said area with the removed surface, to form a wood replacement surface, said wood replacement composition comprising:
- vinyl ester resin in combination with polyester resin;
- a monomer;
- a thickening agent;
- accelerators;
- and
- fillers,
- wherein the resin, the monomer, the thickening agent, the accelerators, and the fillers are thoroughly mixed together prior to being used as a wood replacement composition.
A method of making a sprayable, pourable composition comprising:
- providing a vinyl ester resin of 10-20 weight percent of the composition;
- providing a polyester resin of 40-60 weight percent of the composition;
- providing a monomer of 0-20 weight percent of the composition;
- providing 1-15% thickening agent;
- mixing for about 15 minutes;
- providing 0.1-5 weight percent accelerators selected from the group consisting of DMPT, DMA, DMAA, cobalt octoate, potassium octoate, copper naphthanate, quaternary ammonium salts and mixtures thereof and 0-3 weight percent fumed silica;
- mixing for about 5 minutes;
- providing filler of 1-25 weight percent of the composition;
- and
- mixing for about 20 minutes.
A sprayable, pourable composition useful as a substitute for wood comprising:
- 10-20% by weight vinyl ester resin;
- 40-60% by weight polyester resin;
- a monomer;
- a thickening agent;
- accelerators;
- and
- fillers;
- wherein the resin, the monomer, thickening agent;
- the accelerators, and the fillers are thoroughly mixed together and added to a catalyst prior to being used as a wood substitute.
A boat hull comprising:
- at least one fiber reinforced synthetic plastic layer,
- an intermediate layer of a desired thickness formed from mixing 40-60% by weight polyester resin and 10-20% by weight vinyl ester resin, a monomer, thickening agent, accelerators, filler, and a catalyst, and
- an outer layer.
