Product Detail

Expanded Thermoplastic Microspheres CAS 38742-70-0 DE Type Anti-slip Coating Additive

Product Overview

DE Type Expanded Thermoplastic Microspheres CAS 38742-70-0 are pre-expanded hollow polymer microspheres developed for anti-slip coating systems. Featuring intact closed-cell hollow structure and suitable particle rigidity, the microspheres form micro uneven texture on coating surfaces to enhance friction coefficient and deliver stable anti-slip performance.

Apart from anti-slip function, it acts as ultra-lightweight filler to lower coating density, reduce raw material consumption and improve thermal insulation performance. The product exhibits great dispersibility and can be compatible with solvent-based, solvent-free and two-component coating systems. It will not cause obvious damage to coating hardness, adhesion and weather resistance, serving as an ideal multifunctional additive for various industrial anti-slip coatings.

Core Features

Pre-expanded dry powder, ready to use
No secondary heating expansion required; directly added into coatings to simplify production workflow.
Excellent anti-slip effect
Form micro bump structure on coating surface, effectively improve surface friction and anti-slip property.
Ultra-lightweight closed-cell structure
Realize lightweight modification of coatings while providing thermal insulation and sound absorption performance.
Good dispersion performance
Free-flowing powder, easy to mix evenly with coating raw materials under moderate stirring.
Wide formula compatibility
Compatible with epoxy, polyurethane, acrylic and other common anti-slip coating resins.
Stable coating appearance
Less likely to produce pinholes and bubbles, maintain flat coating surface under reasonable formulation.

Product Specifications

Product Name: DE Type Expanded Thermoplastic Microspheres

CAS No: 38742-70-0

Appearance: White free-flowing dry powder

Core Function: Anti-slip modification, lightweight filling, density reduction, thermal insulation

Applicable Systems: Epoxy anti-slip coating, pavement coating, floor coating, industrial anti-slip finish

Recommended Dosage: 2%–10% based on total formula weight, adjust according to target anti-slip demand

Application Scope

Widely used in all kinds of anti-slip coating projects: workshop floor anti-slip coatings, pedestrian pavement coatings, ship deck anti-slip finishes, stair anti-slip coatings, parking lot floor materials, machinery equipment anti-slip protective coatings and so on. Suitable for construction, shipping, machinery manufacturing and transportation industries.

Usage Guide

Add DE type expanded microspheres at the later stirring stage of coating preparation. Adopt low-speed stirring to avoid microsphere shell breakage caused by high shear force. Control stirring time properly to guarantee uniform dispersion. Adjust addition amount to balance anti-slip performance and coating surface effect. Seal packaging tightly to prevent moisture absorption during storage.

Packaging & Storage

Packaging: Moisture-proof composite bags or lined fiber drums.

Storage: Store in cool, dry and ventilated warehouse. Keep away from moisture, heavy extrusion and direct sunlight.

Shelf Life: 12 months under standard dry storage environment.

Our Advantages

Our DE Type expanded thermoplastic microspheres have complete spherical structure, uniform particle size and stable performance. Compared with traditional quartz sand anti-slip aggregates, it can realize lightweight anti-slip coatings and reduce overall coating weight. Factory direct supply, stable batch quality, free sample testing and professional formulation technical support are available.
