Description

SILIMER 5140 is a polyester modified silicone additive with excellent thermal stability. It is used in thermoplastic products such as PE, PP, PVC, PMMA, PC, PBT, PA, PC/ABS, etc. It could Obviously improve the scratch-resistant and wear-resistant surface properties of products, improve the lubricity and mold release of the material processing process so that the product property is better. At the same time, SILIMER 5140 has a special structure with good compatibility with the matrix resin, no precipitation, no effect on the appearance and surface treatment of products.

How to use

Addition levels between 0.3~1.0% are suggested. It can be used in classical melt blending process like Single /Twin screw extruders, injection molding and side feed. A physical blend with virgin polymer pellets is recommended.

Transportation & Storage

This product could be transported as non-hazardous chemical. It is recommended to be stored in a dry and cool area with temperature below 40 ° C to avoid agglomeration. The package must be well sealed after opening to prevent products from being affected by moisture.

Package & Shelf life

The standard packaging is a PE inner bag and outer carton with net weight of 25kg. Original characteristics remain intact for 12 months from the date of production if kept with recommended storage method.It occurs that the surface defects during and after the application of a coating and painting. Meanwhile, these defects have a negative influence on both the optical properties and its protecting quality. There are some typical defects, such as poor substrate wetting, crater formation, and non-optimal flow (orange peel). One of the most significant parameters for all these defects is the surface tension of the materials involved.

Some special additives, It is widely used in many coating and painting makers, preventing surface tension defects. However, most of them will influence the surface tension and minimize the surface tension differences.

Our silicone additives can be widely used in coating and paint formulations. From a microscopic point of view, since polysiloxane can strongly reduce the surface tension of liquid paint according to its chemical structure, the surface pressure of coating and paint can be stabilized at a relatively low value. In addition, silicone additives improve the surface slip of dried paint or coating films while increasing scratch resistance and reducing the tendency to clog.
