EV-B303 Resin Specification (English Version)
Basic Information
Product Description: Silicone Resin Curing Agent

Production Code: EV-B303

Appearance: Colorless Transparent Liquid

Product Overview

EV-B303 resin is an amine-functional, solvent-free liquid silicone resin. It can chemically react with organic resins containing epoxy, carboxyl, isocyanate or acrylate functional groups to form silicone-organic copolymers, which is able to improve the physical properties and long-term performance of paints and coatings.

Product Performance

Parameters (Component A)

Solid Content (%): 100

Specific Gravity: 1.11~1.13

Viscosity (mm²/s): 100~300

Amine Equivalent (g/NH): 240~250

Application Characteristics

- Solvent-free liquid silicone resin

- Excellent compatibility with organic resins

- Reduces water absorption, and improves initial gloss, flexibility, heat resistance and weather resistance

Scope of Application

EV-B303 resin can be used alone or mixed with aliphatic amine crosslinkers to endow different coating systems with polysiloxane properties. It is especially suitable for epoxy resin systems. By adding EV-B303 resin (24% resin content), the acid resistance of bisphenol A-type, bisphenol F-type and cycloaliphatic epoxy resins is improved. The addition of a minimum of 6% EV-B303 resin can enhance the wet adhesion and mandrel bend performance of bisphenol A-type and bisphenol F-type epoxy resins.

Storage Conditions

Storage Requirements: Seal tightly, store in a cool and well-ventilated place, avoid direct sunlight, and keep at room temperature. The shelf life is 12 months in unopened original packaging.

Precautions: This product will cure upon contact with moisture. Please use it as soon as possible after opening. If it cannot be used up completely, it is recommended to reseal the container immediately for airtight storage.
