High Temperature Expanding Microspheres CAS 38742-70-0 Automotive Paint Anti-slip Coating Matting Agent

Product Overview

High Temperature Expanding Microspheres CAS 38742-70-0 are multifunctional coating modifiers professionally developed for automotive paint and industrial anti-slip coating systems. Adapted to high-temperature baking and curing processes of automotive coatings, the microspheres expand uniformly under high-temperature conditions to form microscopic and uniform concave-convex texture on the paint film surface. This product effectively converts high-gloss coating surface into soft matte finish, provides stable anti-slip performance, and significantly improves surface wear resistance and touch feeling. Featuring excellent high-temperature resistance, outstanding compatibility with water-based and solvent-based automotive paint systems, long-lasting texture stability and no yellowing, it is an ideal matting and anti-slip functional additive for high-grade automotive interior and exterior coatings.

Core Features

Dual Functions of Matting & Anti-slip: Forms delicate micro rough structure after thermal expansion, effectively eliminating mirror glare of paint film. It achieves uniform soft matte effect while improving surface friction coefficient to solve slippery surface problems of traditional automotive coatings.

High Temperature Process Resistance: Stable expansion performance under automotive paint high-temperature baking conditions. No shrinkage, rupture or yellowing during curing, perfectly matching standard automotive coating production processes.

Excellent Coating System Compatibility: Ultra-fine powder disperses evenly in various automotive paint formulations without agglomeration, floating powder or pinhole defects. It does not affect paint film adhesion, leveling and hardness performance.

Enhanced Wear & Scratch Resistance: The formed micro-texture structure improves the wear resistance and scratch resistance of the coating surface, effectively resisting daily friction damage and extending the service life of automotive paint layers.

Long-Lasting Surface Effect: Stable microscopic texture will not fade or fail with long-term use. The matte degree and anti-slip performance remain consistent, maintaining stable and high-grade coating appearance for a long time.

Improve Product Grade & Hand Feel: Optimizes the flat and rigid plastic sense of ordinary automotive coatings, creating delicate, uniform and textured surface touch, greatly improving the decorative grade of automotive parts.

Product Specifications

Product Type: Automotive Paint Matting Agent, Anti-slip Coating Functional Additive

Processing Temperature Resistance: High temperature baking resistant for automotive coating curing

Appearance: White Ultra-Fine Powder

Applicable System: Water-based / Solvent-based automotive paints, interior and exterior anti-slip coatings, decorative matte coatings

Core Function: Paint matting, anti-slip modification, wear resistance improvement, surface texture beautification

Recommended Dosage: 1.0%–3.0% (Adjustable according to matte degree and anti-slip requirements)

Application Scope

Widely used in surface modification of various automotive functional coatings. Mainly applicable to automotive interior parts matte paint, exterior anti-slip protective coating, automotive plastic parts finishing paint, automobile decorative coating and other fields. It is also suitable for high-grade industrial matte anti-slip coatings that require high temperature resistance, uniform matte effect and stable anti-slip performance.

Usage Guide

Add high-temperature expanding microspheres into paint slurry under low-speed stirring at room temperature, disperse slowly and uniformly. Avoid high-speed shear stirring to prevent microsphere breakage and premature expansion. After full dispersion, perform conventional painting, spraying and coating construction. Complete stable micro-expansion and surface texture forming during standard high-temperature baking and curing process. Adjust microsphere dosage, coating thickness and curing parameters according to target matte effect and anti-slip standard. Keep sealed and moisture-proof during operation and storage.

Packaging & Storage

Packaging: 25kg sealed moisture-proof composite bag with inner PE liner, dust-proof and leak-proof, suitable for industrial bulk supply and long-distance transportation.

Storage: Store in dry, cool and ventilated indoor warehouse, keep tightly sealed at all times. Avoid direct sunlight, high temperature accumulation and humid environment to prevent caking and spontaneous foaming. The standard shelf life is 12 months under qualified storage conditions.
