Does WPC products need to be painted?

Recently , there are many customer lettered us to inquire thatdoes WPC products need to be painted? Why would someone sell the oil paint for Wood Plastic Composite products? LeadWPC here to solve the problems for you.

WPC is divided into PVC material and PE material. Generally, the PVC products used in outdoor need to be painted, and usually applied to exterior building facades and cladding cases. The main purpose of painting is to prevent and protect the surface from the water and moisture of the air, and to avoid the color fading problem by oxidation of the PVC material by UV irradiation, thus the product’s life span can be prolonged. People often chooseclear varnish or UV paint to paint it.  The outdoor application WPC PE products and outdoor furniture WPC PE products donot require any painting.

So, how is the painting effect of PVC types of WPC materials?

WPC is a kind of wood-plastic composite material, which combined by wood flour, calcium and other additives, so the surface isglossy and smooth due to the resin, but is also a bit of matte,the surface friction is relatively large. LeadWPC had did some experiments to compare the adhesion of varnish, uv paint and regular paints, the corresponding results show that PVC WPC paint adhesion is very good, and the material stability of PVC is high, so theadverse reaction will not be occurred.

The effect of painting WPC material and anticorrosive wood products aredifferent, WPC material often paint for enhancing the brightness and to protect the products. It do not need to repaint or keep regular maintenance.And for painting anticorrosive wood applied in outdoor pavilion, decking and fence etc., the main purposes areas follows: the first is waterproof, the waterproof effect of anticorrosion wood is bad,so the painted surfaces can prevent the penetration of watereffectively, andslow down its rotten. The second is to prevent discoloration, traditional wood will be carbonized and go dark after using around 2 years in the outdoor space, that’s inaesthetic, so, generally the real wood projects should be painted every year, to isolate the air to slow down the speed of carbonization of wood .

In short, WPC PVC products need to be painted, and the adhesion is pretty well, the decoration effect will be better after painting.
