They are specially developed as foaming additives for water-based coatings.
Low Temperature Expandable Microspheres CAS 38742-70-0 Thermoplastic Foaming Agent for Water-based Coatings 80-110℃
Product Overview
CAS 38742-70-0 Low Temperature Expandable Microspheres are high-performance thermoplastic foaming agents specially designed for water-based coating systems. Featuring a low foaming temperature range of 80℃–110℃, the microspheres can achieve uniform and stable expansion under mild heating conditions. With excellent water compatibility, low activation temperature and stable foaming efficiency, this product effectively solves the high-temperature damage problem of water-based coatings, perfectly balancing lightweight performance, flat coating texture and production applicability. It is an ideal eco-friendly foaming additive for water-based industrial coatings.
Core Features
Low Temperature Foaming & Wide Adaptability: Special low-temperature activation design, complete uniform expansion at 80–110℃, adapts to low-temperature curing process of water-based coatings, no coating yellowing or substrate damage.
Stable & Controllable Foaming Effect: Consistent microsphere particle size, controllable expansion ratio, form fine and closed-cell foam structure, endow coating with delicate matte texture and lightweight performance.
Eco-friendly & Low Odor: Thermoplastic microsphere structure, no harmful volatile substances during foaming, low odor, compliant with environmental protection standards for water-based coating applications.
Improve Coating Performance: Effectively reduce coating density, enhance scratch resistance, heat insulation and anti-slip properties, optimize surface hand feel and appearance of finished coatings.
Product Specifications
Product Name: Low Temperature Expandable Microspheres
CAS No: 38742-70-0
Product Type: Thermoplastic Foaming Agent
Foaming Temperature Range: 80℃–110℃
Appearance: White Fine Powder
Applicable System: Water-based Coatings & Water-based Slurries
Core Function: Low-temperature foaming, lightweight, matte texture modification
Recommended Dosage: 0.5%–3.0% (Adjustable according to foaming requirements)
Application Scope
Widely used in all kinds of water-based coating products requiring low-temperature foaming and lightweight modification. Mainly applicable to water-based matte coatings, water-based texture coatings, architectural water-based paints, textile coating slurries, leather finishing coatings, anti-slip water-based coatings and other fields. It is the preferred additive for water-based coating manufacturers to upgrade product texture and reduce material cost.
Usage Guide
Add the expandable microspheres into water-based coating slurry at low-speed stirring state, stir evenly to avoid high-speed shear damage to microsphere structure. Complete dispersion at room temperature, and foaming molding can be realized during subsequent low-temperature drying and curing process. Adjust the addition amount and curing temperature appropriately according to the required foaming height, texture fineness and lightweight degree. Seal and isolate moisture during operation.
Packaging & Storage
Packaging: 25kg sealed moisture-proof packaging, safe and dust-proof, suitable for industrial bulk transportation.
Storage: Store in dry, cool and ventilated warehouse, keep tightly sealed. Avoid high temperature, direct sunlight and humid environment to prevent spontaneous foaming and agglomeration. The shelf life is 12 months under standard storage conditions.
