Dry Expanded Hollow Microspheres CAS 38742-70-0 Paint Matting Agent Surface Texture Modifier
Dry Expanded Hollow Microspheres CAS 38742-70-0 are pre-expanded hollow polymer microspheres used as paint matting agent and surface texture modifier. With stable spherical structure, they form tiny uneven microstructures on coating surface to deliver matte effect and delicate texture. Meanwhile, they serve as lightweight filler to reduce coating density and improve thermal insulation property. The microspheres exhibit good dispersibility and compatibility with various paint systems, and impose
Dry Expanded Hollow Microspheres CAS 38742-70-0 Paint Matting Agent Surface Texture Modifier
Product Overview
Dry Expanded Hollow Microspheres CAS 38742-70-0 are pre-expanded hollow polymer microspheres, developed as multifunctional additive for paints and coatings. With stable spherical particle structure, they form fine micro unevenness on coating surface to realize matte effect and create delicate surface texture.
Besides matting and texture adjustment, the microspheres act as lightweight filler to lower coating density and enhance thermal insulation performance. They feature excellent dispersibility and wide compatibility with solvent-based, water-based and solvent-free coating systems. Reasonable dosage will not severely damage coating adhesion, hardness and weather resistance. It is an ideal multifunctional additive for matte coatings, textured paints and industrial surface finishes.
Core Features
- Pre-expanded dry powder, easy to disperseDirectly added into paint formula without heating treatment.
- Excellent matting & texture forming performanceForm micro bump structure on coating surface to obtain uniform matte effect and tactile texture.
- Lightweight hollow structureReduce coating density and provide certain thermal insulation function.
- Good compatibility with various resinsAdaptable to acrylic, polyurethane, epoxy and other common coating resin systems.
- Stable film performanceLess likely to trigger pinholes and bubbles under proper formulation.
- Adjustable surface touchDifferent addition amounts can achieve diversified matte and texture effects.
Product Specifications
Product Name: Dry Expanded Hollow MicrospheresCAS No: 38742-70-0Appearance: White free-flowing dry powderCore Function: Matting modification, surface texture adjustment, lightweight fillingApplicable Systems: Water-based paint, solvent paint, matte coating, textured coating, industrial finishRecommended Dosage: 1%–7% based on total formula weight, adjust according to target matte degree and texture requirement
Application Scope
Suitable for interior and exterior matte architectural coatings, textured wall paints, furniture matte coatings, plastic surface coatings, equipment anti-glare finishes, decorative texture coatings and other products. Widely used in architectural decoration, furniture manufacturing, plastic hardware and industrial coating industries.
Usage Guide
Add microspheres in later dispersion stage of paint production. Low-speed stirring is recommended to avoid high shear breaking microsphere shells. Control stirring speed and duration to guarantee uniform dispersion. Optimize dosage to balance matte effect, surface texture and mechanical properties of coating film. Keep package tightly sealed to prevent moisture absorption.
Packaging & Storage
Packaging: Moisture-proof composite bags or fiber drums with inner plastic liner.Storage: Store in cool, dry and ventilated warehouse. Keep away from moisture, heavy extrusion and direct sunlight.Shelf Life: 12 months under dry storage conditions.
Our Advantages
Our dry expanded hollow microspheres have complete spherical structure, narrow particle size distribution and stable batch performance. It integrates matting, texture modification and lightweight filling into one material, reducing usage of multiple additives. Factory direct supply, sufficient stock, free sample testing and coating formulation technical support are available.
