MK-605 Silicon Dioxide Powder

1) Relationship between MK-605 silica dioxide and plastic coating

MK-605 silica dioxide belongs to an agent which is suitable to use in plastic coating to reduce surface glossy. It is mainly made by

silicon dioxide's tiny particles. It is added into coatings to create a rough surface texture. This texture can scatter the light that is shining

on the coatings' surface which can reduce surface's reflection and create matte effect.

MK-605 silica dioxide is commonly used into plastic coatings in various applications like auto parts, furnitures and electrical equipments.

This type silica dioxide can not only be used in solvent coatings but  also in water based coatings. Adjusting silica dioxide's using content

can help coatings arrive the expected glossy. Comparing with other types silica Matting Agent, MK-605 silica matting agent has many

advantages. It has stable chemical properties and is effective in reducing coatings' glossy. Besides, MK-605 silica matting agent is

compatible with different coatings. Cause it has low influences on coatings' adhesive property.

Overall, silica matting agents are important additives in plastic coatings, providing a cost-effective way to achieve matte effects on a

variety of surfaces.

2) What can silica matting agent change the plastic coatings?

The main silicon dioxdie that is used in plastic coating is nano size silica or micro size silica. These two types of silica can be used as filler,

enhancer or functional additive. They can give plastic products a variety of properties.

Below are the common advantages that using silica matting agent in plastic coatings.

1. Enhancing mechanical properties: adding silica particles can enhance plastics hardeness, roughness and scratches resistance obviously.

This is because silica dioxide has super high hardeness and heating resistance which can enhance plastics based structure.

2. Enhancing surface properties: silica matting agent can change plastic coatings' surface physical properties like hydrophilic or hydrophobic. 

3.Enhancing UV radiation resisting properties: silica particles has excellent resisting function for UV radiation. So we can add silica matting agent

into plastics that are resisting to UV light which can extend products using life.

4. Improving heating stability: silica matting agent's high melting point and low coefficient of thermal expansion make it being effective

component for improving plastics heating stability.
