Fiberglass statue reinforced plastic sculpture coloring is to process the surface of the sculpture made of fiberglass reinforced plastic, which is generally divided into color painting, monochrome paint, and imitation stone metal effect. Each effect has different technology to achieve, and the precision and professionalism of the process directly affect the quality and final effect of the sculpture.
The most important thing before coloring Fiberglass statue sculpture in wax removal. If it is washed before waxing for the first time, it is mainly for the non-sticky wax of the back polished sandpaper. It can be laundry powder (which can be polished with soap and water without wax on sandpaper), acetone and Tiannashui.
The wax produced by polishing after water milling is also wiped with acetone.
The waxy dirt of the mold on the production line before coloring of Fiberglass sculpture, including wax, resin, and other attachments, is usually wax dirt caused by the micro-hole, uneven, unclean, cracked slit of the mold. The general shape of the wax dirt is rough protuberance. If it is a crack, it is the protuberance on this line.
In fact, these wax scales can not be removed with detergents. These so-called wax scales are not simple wax layers, but also attached to resin coatings and other things.
Mold maintenance, regular water grinding, polishing, waxing treatment, crack grinding repair treatment. Wax scale found before regular maintenance can be treated with sandpaper and local waxing.
Some Fiberglass sculptures are painted in a single tone, so they can be directly sprayed with paint (nitro paint). Alkyd paint. Cold baking paint is OK)
Nitro lacquer Fiberglass statue sculpture coloring:
Nitro paint is a common wood and decoration paint. The main film-forming substance of nitrocellulose paint is nitrocellulose, which is composed of alkyd resin, modified rosin resin, acrylic resin, amino resin, and other hard and soft resins.
In general, plasticizers such as dibutyl phthalate, dioctyl ester, and oxidized castor oil need to be added. The main solvents are esters, ketones, alcohol ethers, and other real solvents, alcohols, and other cosolvents, as well as benzene and other diluents.
Nitro paint is mainly used in wood and furniture painting, home decoration, general decoration painting, metal painting, general cement painting and so on.
If the budget is limited, choosing nitro lacquer to color Fiberglass sculptures is also one of the cheaper ways.
Alkyd lacquer Fiberglass statue sculpture color:
Alkyds Coatings, alias alkyd resin paint or alkyd resin paint, mainly composed of alkyd resin, is the largest class of paint in China. It has the advantages of low price, simple construction, low requirement for construction environment, full and hard coating, good durability and weatherability, good decoration and protection.
The disadvantage is that the drying is slower, the film is not easy to meet higher requirements, and it is not suitable for high decorative occasions.
Alkyd paint is mainly used in general wood, furniture and home decoration painting, general metal decoration painting, less demanding metal anti-corrosion coating, general agricultural machinery, automobiles, instruments, industrial equipment painting and so on.
Alkyd paint is usually used for coloring large Fiberglass sculptures, which has good durability and weatherability.
Cold-baked Fiberglass sculpture coloring:
Cold-baked Fiberglass sculpture coloring is generally used in small Fiberglass sculpture manufacturers without professional lacquer room and drying equipment. This process will cause serious dust spots and uneven paint surface of Fiberglass sculpture. It is mostly used in low-end beautiful sculpture, such as high-end artworks can not use this method.
High-end painted Fiberglass statue sculpture coloring:
Let’s take a look at the differences between high-end baked Fiberglass sculpture coloring and ordinary spray painting.
1. Technological identification
The baking varnish is to primer three times and finishes four times on Fiberglass sculpture. Every time it is painted, it is sent to the dustless barn for baking. Spraying varnish polishes cloth on Fiberglass sculpture and sprays paint on it to dry naturally.
2. Identification from the paint film
Touch the surface of the painted Fiberglass sculpture with your hand to see if it is smooth and voucher, and observe whether the color of the edge is the same as that of the whole sculpture. If the edge is smooth, the same color paint film uniform, full color is high-end baking paint.
The edge of the spray paint is rough, the color is lighter than the whole, and the paint film is not uniform, the color is not full.
Composite color Fiberglass sculpture is divided into color painting and imitation of copper, imitation of stone, imitation of stainless steel and other surface effects, most of which are nitro paint and alkyd paint. Oil and propylene can also be used but not durable.
One of the most common coloring methods for Fiberglass sculpture is spraying plastic coat on the mold, hand coloring, casting, molding, water milling, and polishing, and the other is pouring, demolding, hand pasting paper, spraying resin commodity polishing or spraying high-gloss varnish, which usually does not use oil, but also waxing.
Fiberglass statue sculpture manufacturing technology is characterized by simple one-time forming. Although there are many advantages of Fiberglass sculpture, the quality of the sculpture will be different due to the different materials used. For example, if the finished Fiberglass sculpture products are placed outdoors in the sun and rain for a long time, it will appear cracking, dim color, unable to show its due role.
