Technical Indicators Of Vinyl Resin (1)

How to choose Vinyl Resin? This is a concern of many downstream companies of chloroacetate resins. Compared with other products, chloroacetic resin can still be tested and tested to ensure the product is feasible.

As a Vinyl Resin Factory, Pan Gao Chemical has a view on this piece of nature:

1. Solid content:

Most of them are produced in 50%-70%, 40% and 80%, and can be made into different solid contents according to user requirements. Under normal circumstances, high solid content is used for varnish and varnish. Solid solid paint, top coat. The low solid content is mostly on the silver paint and primer.

2. Viscosity:

The size of the viscosity reflects the size of the molecular weight. In order to ensure the performance of the resin after painting, the viscosity of the thermoplastic resin should be larger (because it is volatilized and dry), and the control of the viscosity depends entirely on the application and performance requirements of the resin, such as: resin for ink, especially screen ink, The viscosity of the resin should be small, the drying rate is slow, and it is prevented from plugging into the wire mesh; the requirement for making a transparent putty is larger and the viscosity is higher. Because it is thickly coated, it prevents precipitation of pigments and fillers.

Under normal conditions, low viscosity is used for varnish and varnish. Medium viscosity paint and topcoat. High viscosity is used in silver paint and primer.

Many users only seek immediate benefits. They hope that the viscosity of the resin will be as large as possible, and more solvents can be added to reduce the cost of the paint. However, doing so may sacrifice gloss, leveling, workability and miscibility.
