CAS 38742-70-0 Wet Cake Expandable Microspheres serve as dedicated 3D embossing additives for aqueous coating systems. Presented in wet cake form, the microspheres disperse smoothly in water-based formulations without agglomeration. Upon heating, they expand evenly to form fine closed-cell structures, generating distinct three-dimensional embossing texture on coating surfaces. This product delivers stable stereo tactile effect, improves decorative performance, and maintains good compatibility wi

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

Product Overview

Wet Cake Expandable Microspheres CAS 38742-70-0 is a professional thermoexpandable functional additive specially developed for water-based 3D embossing and texture coating. Different from traditional slurry and dry powder microspheres, it adopts high-purity wet cake form with higher effective content and lower moisture interference. It disperses perfectly in all aqueous systems without agglomeration or precipitation.

Remaining stable at room temperature without premature expansion, the microspheres expand uniformly during heating and curing, forming fine closed-cell microstructures on the coating surface. It creates vivid 3D stereo embossing texture, soft matte tactile effect and uniform bump patterns. Widely used for water-based wall coatings, textile printing paste, wallpaper embossing and decorative waterborne materials, this product is a high-efficiency, stable and cost-effective 3D embossing agent for aqueous coating industries.

Core Features

High-Purity Wet Cake StructureAdopts filter cake molding with higher microsphere content than ordinary wet slurry. Low impurity and low water content, effectively avoiding formula dilution and coating defects.

Excellent 3D Embossing PerformanceControllable thermal expansion forms consistent micro-bump texture. Delivers clear stereo effect, uniform matte finish and comfortable tactile feeling for coating surfaces.

Super Water-Based CompatibilityFully compatible with water-based acrylic emulsion, polyurethane resin, printing paste and other aqueous materials. No pinholes, no cracking, no floating particles after film formation.

Stable Anti-Premature Expansion PerformanceKeeps intact during normal temperature stirring and mixing. No early foaming, ensuring ultra-stable batch production and repeatable embossing effect.

Upgrade Coating Decoration & PerformanceEffectively improve coating three-dimensional sense, scrub resistance and thermal insulation, greatly enhance product grade and market competitiveness.

Eco-Friendly Physical FoamingPure physical expansion, low VOC, odorless and non-toxic. Complies with international environmental protection standards for architectural decoration and textile materials.

Product Specifications

Product Name: Wet Cake Expandable Microspheres

CAS Number: 38742-70-0

Appearance: White uniform wet cake

Core Function: 3D embossing, stereo texture forming, matte bump finishing, lightweight foaming

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

Processing Technology: Room temperature dispersion + thermal curing expansion

Recommended Dosage: 1.0%–4.0% (adjustable by embossing depth and texture requirements)

Application Scope

This wet cake microsphere is specially designed for water-based 3D embossing scenarios. It is widely applied in embossed wall texture coatings, textile 3D printing paste, wallpaper foamed embossing layers, water-based leather finishing agents, matte anti-glare decorative coatings and other aqueous functional coating fields. It replaces traditional chemical foaming agents to achieve finer, more uniform and softer stereo embossing effects.

Usage Guide

Disperse the wet cake microspheres into water-based raw materials via low-speed stirring at room temperature. Avoid high-speed shearing and overheating to prevent particle damage and premature expansion. Complete thermal expansion and 3D embossing molding during heating and curing process. Adjust dosage, curing temperature and time according to target stereo effect. Keep sealed and stored in cool environment for long-term activity.

Packaging & Storage

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

Storage: Store in cool, dry and ventilated warehouse. Keep tightly sealed, avoid direct sunlight, high temperature and freezing environment. Standard shelf life is 12 months under proper conditions.

Our Advantages

Our wet cake expandable microspheres feature high effective content, uniform particle size and stable expansion performance. Compared with ordinary wet slurry products, it provides stronger embossing stereoscopic effect and better formula stability. We support factory direct sales, stable bulk supply, free sample testing and professional formulation technical guidance, helping customers upgrade coating texture and reduce production costs.
