CAS 38742-70-0 Wet Cake Expandable Microspheres act as high-efficiency 3D embossing agents specially designed for aqueous coating systems. Supplied in wet cake form, the microspheres disperse easily in water-based formulas without agglomeration. Upon heating, microspheres expand controllably and form uniform closed-cell structure, creating distinct stereo embossing texture on coating surface. This product delivers stable embossing performance, enhances coating tactility and decorative effect, an

CAS 38742-70-0 Wet Cake Expandable Microspheres Aqueous Coating 3D Embossing Agent

Product Overview

Wet Cake Expandable Microspheres CAS 38742-70-0 are professional thermoexpandable functional agents specially developed for water-based coatings and printing paste 3D embossing. Different from dry powder and wet slurry types, this wet cake grade features high microsphere content, low water residue and excellent dispersion performance in aqueous systems.

With stable unexpanded state at room temperature, the microspheres will not expand prematurely during mixing. After heating and curing, they expand uniformly to form dense closed-cell structures, creating vivid three-dimensional embossing texture, matte bump effect and excellent stereo tactile feeling on coating surfaces. Widely used for water-based architectural embossing coatings, textile 3D printing paste, wallpaper embossing layers and decorative waterborne coatings, it is a high-efficiency 3D embossing and texture-forming additive.

Core Features

Special Wet Cake FormHigh-purity microsphere filter cake with low moisture content, higher effective content than ordinary wet slurry. No settling, no floating, easy to mix into water-based systems.

Perfect for 3D Embossing EffectControllable thermal expansion produces uniform micro-bulges on coating surface, delivering stable stereo embossing, matte texture and soft touch feeling.

Excellent Water-based CompatibilityFully compatible with all aqueous resins, emulsions and waterborne pastes. No agglomeration, no pinholes, no surface defects after film forming.

Stable Processing PerformanceNo premature expansion during low-speed stirring and normal-temperature mixing. Consistent embossing effect in mass production with high repeatability.

Improve Coating Decoration & DurabilityOptimize surface texture, enhance scrub resistance and heat insulation performance, upgrade coating grade and added value.

Eco-friendly & Low VOCPhysical foaming principle, odorless, non-toxic and environmentally friendly, meeting global environmental standards for decorative coatings and textile printing materials.

Product Specifications

Product Name: Wet Cake Expandable Microspheres

CAS No: 38742-70-0

Appearance: White uniform wet cake

Product Function: 3D embossing, texture forming, matte bump, lightweight foaming

Applicable System: All water-based coatings, waterborne printing pastes, aqueous decorative slurries

Processing Method: Room temperature mixing + heating curing expansion

Recommended Dosage: 1%–4% (Based on embossing depth and texture requirements)

Application Scope

This wet cake microsphere grade is mainly used for 3D stereo embossing and texture modification of water-based systems. Typical applications include architectural embossing wall coatings, textile 3D printing paste, wallpaper foamed embossing layers, leather water-based finishing agents, decorative matte bump coatings and other waterborne functional coating fields. It significantly improves surface stereo effect, replaces traditional chemical foaming agents, and achieves finer and more uniform embossing texture.

Usage Guide

Disperse wet cake microspheres evenly into water-based materials through low-speed stirring at room temperature. Avoid high-speed shearing and overheating to prevent early expansion. Complete thermal expansion and 3D embossing molding during coating heating and curing process. Adjust dosage, curing temperature and time according to target embossing effect. Keep sealed and avoid high temperature storage.

Packaging & Storage

Packaging: Professional sealed packaging for wet cake materials, moisture-proof and leak-proof, suitable for industrial bulk transportation.

Storage: Store in cool, dry and ventilated environment, keep tightly sealed. Avoid sunlight, high temperature and freezing. Shelf life: 12 months under standard storage conditions.

Our Advantages

We supply high-stability wet cake expandable microspheres with high effective content and uniform particle size. Compared with ordinary wet slurry products, our wet cake grade provides stronger embossing effect, less water interference and more stable formula compatibility. Factory direct supply, stable batch consistency, free sample test and professional technical support are available to help customers upgrade coating texture and reduce formulation costs.
