Abstract
A natural strip or strip-based weaving or weave fabric product or a natural strip or strip-based woven product is coated and protected with a crosslinking polyvinyl acetate (XPVAc or x-PVAc) adhesive. Said adhesive is applied and cured on the exterior surfaces of said product as a first coating layer or a primer in combination with a coating layer of acrylic, alkyd, asphalt, epoxy, latex, polyurethane, silicone coatings, urethane, vinyl ester, etc. coated over the cured adhesive as a second coating layer or a topcoat. Said product is woven or fabricated with stalks, stakes, staves, stems, sticks, strands, shoots, splints, straws, strings, twigs, bark, branches, laths, leaves, rods, roots, whicker, etc. of a fiber plant, a tree, or a crop, or the combination thereof.
Claims22
A waterproofing composition of a crosslinking polyvinyl acetate adhesive for application to the exterior surfaces of a natural strip or strip-based weaving or weave fabric product or a natural strip or strip-based woven product, comprising:
- a) a polyvinyl acetate-based adhesive resin;
- b) a copolymer;
- c) a crosslinking agent;
- and
- d) a catalyst;
- wherein said crosslinking polyvinyl acetate adhesive is a Type I or Type II adhesive and applied and cured on at least one portion of the exterior surfaces of said product, such that said adhesive forms into a protective coating film and is on the exterior surfaces of said product;
- wherein said product is woven or fabricated from strip or strip-like weave elements or units, including strands, stakes, stalks, staves, sticks, stems, straws, strings, splints, shoots, laths, leaves, bark, branches, rods, roots, twigs, or wickers of a fiber plant, a tree, a crop, or the combination thereof;
- and
- wherein said adhesive improves the water resistance, dimensional stability, and durability of said product.
A natural strip or strip-based weaving or weave fabric product or a natural strip or strip-based woven product being coated with a crosslinking polyvinyl acetate adhesive;
- said product comprising strip or strip-like weave elements or units, including strands, stalks, sticks, stakes, staves, stems, straws, strings, splints, shoots, bark, branches, laths, leaves, rods, roots, twigs, or wickers of a fiber plant, a tree, a crop, or the combination thereof;
- said strips working as wefts, warps, or both in the formed weave structure or pattern of said product;
- wherein the crosslinking polyvinyl acetate adhesive is a Type I or Type II adhesive and at least includes a polyvinyl acetate-based adhesive resin, a crosslinking agent, and a catalyst;
- wherein said adhesive is applied and cured on at least a part of the exterior surfaces of said product, such that said adhesive forms into a protective coating film and is on the exposed exterior surfaces of said product;
- and
- wherein said adhesive improves the water resistance, dimensional stability, and durability of said product.
