The problem of using Vinyl ChlorideVinyl Acetate Terpolymers on oil based wood paint

When we said problem, we should to know more information about oil based wood paint.

Firstly understand the resin system of the wood paint requirement

Ther are four system of wood paint,

A: PU system (alkyd resin, Vinyl Chloride Vinyl Acetate Terpolymers)

B: nitrocellulose system

C: acrylic system

D: water-based system

2. Understand the type of wood paint, light type or matte type?

Primer : Wood paint primer is the undercoat of preparatory coating put on wood, specifically, before you use paint on it. Using a wood primer increases the durability of your paint job, ensures better adhesion of the paint to the surface, and helps protect the wood that's being painted.

When should you use wood primer?

It all depends on the kinds of wood you'll be painting. According to Lowe's, when you're painting new wood that isn't stained, you should be using high-quality latex primer or an oil-based primer. If your new wood is painted or stained, you'll want to use a stain-blocking primer. Older, more weathered wood needs a high-quality latex or oil-based primer.

 Topcoat (usually matte paint)

Top coating is a transparent or translucent coat of paint applied over the underlying material as a sealer. In a paint system, the topcoat provides a resinous seal over the intermediate coats and the primer

3.what is the application formula of Vinyl Chloride Vinyl Acetate Terpolymers?

Used for primer (what's the function?  increases the durability of your paint job, ensures better adhesion of the paint to the surface, and helps protect the wood that's being painted.)

Used for top coat make it more shiny

4. what is the dissolving solvent of Vinyl ChlorideVinyl Acetate Terpolymers?

Wood paint must be ester solvent,  Ketone solvent can be used also

5. What is the requirement for resin fineness and the dissolution of resin?

How many particle or The number of micrometers that the resin fineness should reach is based on the customer's specific application requirements.

Disperse with a high-speed disperser, with a solid content of about XX%. Or use a reactor to raise the temperature to the required temperature, and the dissolution time is also based on the specific requirements of the application.

6. What is the amount of Vinyl Chloride Vinyl Acetate Terpolymers added in the formula?

Answer: Wood paint has a wide range of applications. It is used for high-end woodware or general furniture. The customer's formula is different, and the addition amount is based on the specific test.

7. What is the compatibility of Vinyl ChlorideVinyl Acetate Terpolymers with alkyd resin?

It depends on the customer's application. Some businesses will not pay attention. Concerned wood paint merchants mainly look at whether it will cause the paint to appear flocculent, fineness and paint delamination. These data are generally under the condition that the test conditions are placed at room temperature for 7 to 30 days.

8. What is the main function of vinyl acetate resinVinyl ChlorideVinyl Acetate Terpolymers in wood paint to improve the performance of the paint?

It is Mainly to improve the leveling property, the alignment of the matte powder, the abrasion resistance, flexibility, weather resistance and solvent release of the paint film.

Unfinished wood should always be primed prior to painting. Primer, having high-solids content, helps fill in the wood grain and creates a smooth surface for the finish coat. Like the raw drywall, unfinished woods tend to really soak up paint, and primer helps seal the surface to prevent this from happening

Despite all of the hype surrounding “Paint and Primer in One” products, there are many situations where a coat of primer on its own is crucial to properly preparing a surface (interior or exterior!) for a paint job.  While “Paint and Primer in One” products are often an excellent choice for previously painted interior surfaces that are in good condition, we find that most other situations, especially on exterior projects, require a separate coat of primer.

Primer creates a layer that paint can better adhere to.  While applying primer may seem like an “extra” step, you may find that it actually saves you time and money, since primer tends to be less expensive than paint and by using it, you are saving yourself from buying that extra paint.  

Unfinished wood should always be primed prior to painting. Primer, having high-solids content, helps fill in the wood grain and creates a smooth surface for the finish coat. Like the raw drywall, unfinished woods tend to really soak up paint, and primer helps seal the surface to prevent this from happening. Either latex primer or oil-based primer is suitable for raw wood, depending on the type of paint you will use. However, keep in mind that for wood such as cedar or redwood, oil-based primer is actually necessary as it penetrates deeper into the wood, helping to prevent tannin stains
