Hollow glass microspheres H42, H35, H20 as an additive in thermal insulation paints


Description of hollow glass microspheres:

Hollow glass microspheres are hollow, small and round spherical powders containing inert gas. As a new type of filler, it has the advantages of light weight, high strength, good fluidity, heat insulation and corrosion resistance, etc. It is used in lightweight composite materials, coatings, aerospace, deep sea cementing, electrical insulation materials, thermal insulation materials, military explosives It has a wide range of application prospects in such fields as "space materials".

Application of hollow glass microspheres


Hollow glass microspheres are often used as additives in paints and coatings to change and improve the performance of traditional coatings and reduce costs.

Because hollow glass beads have the characteristics of insulation, flame retardant, high and low temperature resistance, anti-corrosion, fire prevention, heat preservation, self-lubrication and good fluidity, large specific surface area and small particle size.

Therefore, it is widely used in various high-temperature insulating paints, high wear-resistant anti-corrosion paints, advanced furniture paints, ship rust anti-corrosion paints, automotive advanced paints, exterior paints for various machinery and equipment, interior and exterior wall coatings for buildings and various thermal insulation coatings. Marine anti-corrosion coatings and fire retardant coatings. 


Why choose hollow glass microspheres for coating and paints?


1) Reduce the weight of the coatings and paints

Hollow Glass Microspheres density is only 0.10-0.62g/cm3.

2) Low thermal conductivity

Coating/Painting added 10% Hollow glass microspheres, it can create 25-40°C temperature difference.

3) Good economy

Compared with other fillers, hollow glass microspheres have the smallest surface area to volume ratio and low oil absorption rate, which can reduce the amount of matrix resin and reduce costs. At the same time, hollow glass beads of the same weight occupy more volume, further reducing the cost. It also reduces VOC.

Improve the thermal insulation properties of the coating and paints

Hollow glass microspheres have low thermal conductivity and high thermal reflectivity due to

their hollowness, which can effectively reduce radiative heat transfer and transfer heat, and

play the role of thermal insulation.

4) Reduce the shrinkage, warpage and impact of the product.

Because of its hollow structure, the hollow glass microspheres will absorb and digest the

impact strength when it is impacted, so that the impact resistance of the paint film is

improved. At the same time, it is isotropic, reducing the shrinkage of the paint film,

improving the crack resistance and heat insulation performance, and also protecting the

paint film from thermal shock caused by the alternation of rapid heating and rapid cooling.

5) Adjust the viscosity of the coating system

Hollow glass microspheres has a smooth surface, low porosity between different particle sizes, low viscosity and good fluidity, which can adjust the viscosity of the coating and improve the fluidity of the coating.
