800cst Epoxy Modified Polysiloxane (CAS 67762-96-3) is reactive epoxy grafted polysiloxane. It can participate in crosslinking reaction with epoxy resin matrix. The flexible siloxane chain buffers internal stress generated during curing, lowering shrinkage rate of epoxy floor coating. It avoids floor cracking, edge warping and peeling issues, meanwhile optimizes coating leveling and wear resistance. Widely used anti-shrinkage modifier for industrial self-leveling epoxy floor coatings.

Product Detail

Product Overview

800cst Epoxy Modified Polysiloxane (CAS 67762-96-3) is tailor-made reactive silicone anti-shrinkage agent for epoxy floor coating industry. Combined reactive epoxy groups and soft siloxane backbone, it overcomes the defect of high shrinkage of pure epoxy materials. Uniformly dispersed in epoxy system, it acts as stress buffer phase during curing, minimizing volume shrinkage and greatly improving long-term stability of epoxy flooring.

Key Features

Reactive epoxy structure, good compatibility with various two-component epoxy systems
Effectively reduce curing shrinkage, prevent coating crack, curling and delamination
Improve coating leveling, eliminate surface shrinkage cavities and brush traces
Enhance surface smoothness, abrasion resistance and substrate adhesion
No negative influence on hardness, gloss and curing speed of epoxy floor

Main Applications

Anti-shrinkage & leveling agent for self-leveling industrial epoxy floor coating
Stress relief additive for epoxy anti-static floor paint
Modifier for epoxy waterproof terrace and parking lot flooring coatings
Surface conditioning auxiliary for indoor workshop epoxy decorative flooring

Usage Guidance

Recommended dosage: 1%–5% based on total epoxy resin weight. Mix fully with component A before adding curing agent. Conduct construction simulation test for shrinkage, hardness and surface appearance before mass production. Adjust dosage according to floor thickness and construction environment.

Storage & Package

Seal drums tightly. Store in cool, dry and ventilated warehouse, avoid high temperature and direct sunlight. Standard package: 200kg iron drum. Shelf life: 12 months under proper storage conditions.

Service Support

Test samples are available for coating laboratory evaluation. Stable bulk supply and epoxy floor formulation technical support. Welcome to inquire TDS, COA and factory quotation.
