500cst Epoxy Silicone Oil (CAS 67762-96-3) is epoxy graft modified polysiloxane. It works as efficient adhesion promoter for condensation silicone sealants. The epoxy functional groups form stable bonding links between silicone polymer and various base materials, remarkably improving adhesive strength. It will not damage storage stability of sealant, widely used additive for construction, electronic silicone sealant formulations.

Product Detail

Product Overview

500cst Epoxy Silicone Oil (CAS 67762-96-3) is professional epoxy modified silicone adhesion promoter tailored for condensation curable silicone sealant. Unique molecular structure combines siloxane main chain and reactive epoxy groups. It migrates to bonding interface evenly during curing, eliminates poor adhesion defects of silicone sealant on many polar substrates without influencing curing speed and shelf life of finished sealant.

Key Features

Greatly improve adhesion of silicone sealant on metal, glass, epoxy, plastic substrates
Good compatibility with neutral condensation silicone rubber systems
No negative impact on sealant storage stability and curing property
Enhance long-term bonding durability under humidity and temperature variation
Low volatility, stable performance during compounding process

Main Applications

Adhesion promoter for neutral silicone construction sealant
Bonding additive for electronic component silicone potting sealant
Modifier for silicone adhesive used in glass assembly
Auxiliary agent for industrial equipment silicone sealing compound

Usage Guidance

Recommended dosage: 0.5%–3.0% based on total silicone sealant formula. Add during planetary mixing stage under moisture-isolated environment. Complete adhesion test on target substrates before mass production. Prevent moisture contamination during operation.

Storage & Package

Seal drums tightly. Store in cool, dry and ventilated warehouse, strictly keep away from moisture. Standard package: 200kg iron drum. Shelf life: 12 months under proper storage conditions.

Service Support

Test samples are available for silicone sealant formulation testing. Stable bulk supply and silicone formulation technical support. Welcome to inquire TDS, COA and factory quotation.
